**TYRE WEAR UPDATE** The rear and the front tyres have now been swapped over for an even baseline to the test - I'll update the below measurements as time goes by: (Front tyre wear vs km since steering knuckles were installed) 0KM: Outside: 8.5mm / Inside: 8.5mm 5000km: Outside: 8.05mm / Inside: 8.0mm 10000km: Outside: 7.6mm / Inside 7.5mm 15000km: Outside: 7.2mm / Inside 7.2mm 20000km: Outside: 6.8mm / Inside: 6.7mm (The above numbers are the end of the test as tyres have now been rotated, but I believe this is conclusive!)
I’ve already got mine booked in. The upper control arms definitely made a difference but still not good enough. I agree with the other comments. Isuzu should be fixing this as a recall
You've answered a lot of questions I've had. I have a mate with a MUX (he calls it Elon) who wore out his factory tyres in not much over 20,000 kms. Because he was new to 4wd ownership, I thought he'd inadvertently run it in H4 on bitumen for an extended period. For what it's worth, the Bridgestone AT tyre deal on my stock Ranger gives me a rotate and balance check every 10,000 kms which I've done. At 30,000 kms they're wearing evenly and have plenty of tread left. Great information, thanks. I think I owe my Mux mate a beer for misjudging him!
This is an issue that Isuzu Australia should be putting right. Make sure you let the relevant authority (ACCC) know this is occurring. Have you tried getting a remedy from Izuzu?
Pretty hard to nail Isuzu if the vehicle has an aftermarket 2 - 3" lift installed (correct toe setting @ static ride height = toe out every time the front suspension compresses / bump steer) @ 9:30 bang on! A decent wheel aligner is hard to find & should cost you somewhat more than the usual toe n go! WELL worth the money though!
Yeah it's quite a hot topic on the FB groups with no confirmed solution from Isuzu (although they have recently acknowledged the issue and provided alternative wheel alignment specs to help, but can't say what impact this will have on the tyre wear at this stage). This is happening to stock vehicles too, although I imagine the effects are definitely magnified by suspension lift etc.
@@explorebound To be honest I didn’t even know that this was a problem with other Dmax owners, I do a lot of towing so I thought that this was only my Dmax issue… I have one 4x4 and one 4x2, I’ve done approximately 90,000 kilometres on both. I’ve replaced 2 sets (all 4) of tyres on each.
I believe people are trying to claim or getting something sorted through the manufacturer, but no luck so far I believe as it probably falls within a technically 'acceptable range' or something along those lines
I had the same issue in 2022 MUX. My AT tyre was worn very badly. Mentioned the issue while doing my third service and dealer took it up to Isuzu and got both the front tyres changed under warranty. Changed the wheel alignment in process as well.

Thanks for the update. As somebody who went from an ifs dual cab, to an older wagon for solid axles, I'm really wanting an ifs again for the sole reason that newer cars are quieter. On long trips that really makes a big difference, I took for granted things like having a conversation with a passenger or being able to hear music lol.

I think Izuzu trades too much of its reliability reputation on their proper trucks. The D Max and Mux tend to get a free ride and owners tend to get the sort straw when warranty issues arise. Also missleading advertising comments suggesting the Mux can tow 3500kg. It can only do that if the vehicle has no accessories, luggage or passengers. To late if you paid the money to tow your new 3500kg van only to find the dealer was lying in regard to everyday situations.

I bought the ISUZU D-Max X Terrain last year (2023) with a 50mm lift, Fuel Rims and MONSTA Tyres. The front tyres have chewed out in less than 12,000kms. The wear is on the outside edges of the front tyres. The feedback I have had from Gardner Autos in WA was that ISUZU gave the wrong settings to the installer when the wheel alignment was done... I work overseas and am home again in May and organized my car to go in for service and to rectify the faulty alignment. I also want two new front tyres as they are close to outside of road legal.

Would love to follow this up. 21 SX Single Cab. Dealership brought the issue up with me after 15,000km. This is definitely an issue from stock and something has to be done. Dealership tried fixing the issue with wheel alignments every service, which I was still wasn’t overly happy with. By 45,000 they were completely bald.
We are in exactly the same boat. Front tyres feathered on inside edges and rotated to the back and wheel alignment done twice on front. Now at 43,000 and the front two tyres are absolutely shot after 28,000km on the front! No warranty claim available according to Isuzu as the tyres have done more than 40,000km. Have had the ute since new and had BF AT's fitted by the dealer from new, not the shit soft things they put on it!
rubber will wear quicker at start as its softer and starting to harden up alot later n wear will slow down the wear rate basically like driving with concrete tires as they get older but we wear less in the latter stages
Awesome Video, it was great to see this as I was researching this issue before buying a D-MAX. Looking back now have you also fitted UCAs or have found they are not needed, with addition to the steering knuckles?
Mate! I've got to say your explanation is the best! You've nailed it. I was considering getting a D-Max and I plan to travel with it up north to Shark Bay, Karijini, see the canyon in Exmouth ...etc. I now wonder if I should still consider the D-Max or look at other utes? Cheers mate.
Thanks mate, glad the info was helpful! In my experience, nothing is perfect when it comes to cars and all models have some sort of drawback. All things considered I’m really happy with the Dmax, I’ve used mine pretty extensively over the last few years, travelling over 60,000km around WA without any issues 🙂
It’s actually the other way around, the front tyres wear faster than rears, especially on utes where front brakes are discs and rear are drums, generally front does a greater proportion of braking
Very dependant on load and where it's placed, I personally know of guys who are chewing thru rear tyres at 30 - 40k pulling heavy trailers and if your a tradie who is in a hurry you could almost halve that
Funny you released this, ive had a lot of wear on the outside of my front 2 tyres (2017 MU-X). I do also think my increase in wheel/tyre size from factory and my 2" lift have contributed to it as i havent yet changed out my upper control arms yet. Just very interesting this is a common issue though regardless.
I would expect this to be a recall by ISUZU / Mazda, looks like a faulty part from factory, plus compensation for those that have had to replace their tyres early. Everyone always bags out the other brands saying Dmax and Hilux are the best, they are no different they both have as many issues just like all brands.
Hay mate any chance you could give me an update on the tyre wear after the steering knuckles were replaced to date mine has done 20k km 4 wheel alignment's and front tyres are gone already thanks keep up the good work
Pretty embarrassing when A-list brand ute has such a fundamental and critical design flaw that has to be fixed by the owner at their expense to enjoy a standard ownership experience. Just to highlight how stupid this is, I am running a GWM cannon with 50mm lift and the same tyres, no rotations after 35,000km and perfectly even wear on all 4. Never had that before in a modified 4WD, glad I didn't pay $20k more to enjoy something like this occurring! I have 9mm wear after the same kms as you on 276/65/18 version of the tyre. Measured in three places across all 4 tyres.
The steering arm on the knuckle looks raised about 25 to 30mm. Lowering the rack and or moving it forwards would do the same. My money would be moving the rack forwards to alter the ackerman geometry, those knuckles are not cheap.
Customer of mine came in with that story. They originally had the settings low because…. Lack of understanding i guess, then he showed me the new specs they set it at and they had jumped to putting it at risk of outside edge wear and fast too…. Seemed like halfway between would have been better
It's a good demonstration of the issue but the testing you did showed toe in, not toe out. Toe in would cause the outside of the tyres to wear prematurely, not the inside. Would have been great to see how some suspension compression altered the geometry (which is obviously what's causing the most issues). Also, I think you mean "minutes" not "seconds" when reviewing the toe angles at about 7:53 .
It's amazing that people pay big money for these Ute's and still they have faults. Really what are you paying for. So much to their engineers getting it right and their road test...
Imagine paying big $ for a new DMAX then having to spend another two and a half grand to get it to steer right??? Absurd. Not to mention the money already wasted on the 2 front tyres. Then everyone walks around muttering the golden line, “you only get what you pay for”. Ludicrous.
Hard for me to say definitively as mines been modified since new, although from what I hear it does affect unmodified vehicles too, just not as badly as a vehicle that's been lifted etc.
I wheel align a lot of vehicles And i also pay attention to bump steer assuming load, and these things are so crazy But look at the angle of the steering arm/trackrod/tie rod/rack end, it points down on an aggressive slope So as the body lowers it flattens out pushing it toe out I’ve taken to trying to guess the bump steer when loaded and bumped But they tend to jump double the toe amount of most other high bad bump steer cars so it’s a moving target The worst bump steer car is still a certain Suzuki van i saw which ii had to give a wheel alignment problem just to make it straight with two people in it.
Been through 3 sets of front tyres at 32000kms. Pretty bad huh. Isuzu is "managing" the issue now (as of Aug 31st) by setting toe in to +5mm, in order to get more even wear. The dealer replaced my front 2 tyres on warranty and then aligned with new settings. When I have some money to upgrade suspension, I'll through those knuckles on as well. As stated by many other owners, 100% should be a recall.
Took me 6 years to fond someone that could align a dmax properly, I was having so much trouble with my 2015 dmax wheel alignment, then I ran into a mate I did my apprenticeship with, he was working at a brake and front end specialist, I asked of he could sort out my dmax, it’s the first wheel alignment I’m happy with, still getting uneven tyre wear, and other still howls around corners, and it still gets bump-steer, and it’s still a fucking piece of shit, but at least it drives straight and doesn’t wander as much…
Was the alignment put back to the Manufactures specs or changed.to fix the problem. Whats the original manufactures setting for the vehicle. Bump steer should wear the tyres 0n both sides of the tyre as the suspension goes up and down.
I have a 2021 BT-50, only done 28k km on the stock H/T tyres (planned to change to A/T at first change. They wore to the wire on the weekend when I was in Perth (live in Kalgoorlie), rang the dealership I purchased from to rectify. Mazda claim the bullbar fitted by arb (bought as part of the car) are at fault. Currently arguing for reimbursement for a new set of front tyres from the dealership
Good luck with GC Motors! The weight of the ARB bar particularly with winch fitted actually mask the problem NOT the other way around! Having said that & if we are being honest, the OEM H/T's never last much longer than 30K regardless. (Max I have seen is 45,000km with regular rotation, perfect tyre pressures (vs factory recommendations) etc. This has been the case on BT50/Ranger since 2013 odd (PX) Cheers
@@mjhmech4903 actually purchased the BT from a different dealership (won't name) but had a lot of back and forth arguments with the service manager over who was liable, tried to place on ARB even though my dealings with Mazda. In the end a family connection with the dealership owner had $800 transferred to my account for two new front tyres- just happened to be A/T fitted; in luck that day
Any word on whether this is the same for 2017 models. A family member has one and inner treads are wearing prematurely. They know little of its previous history though. I’m also considering buying it from them. Happy to do the mod if I’m aware upfront it’s needed.
Thanks for the alert - I guess the elephant in the room is how it affects your manufacturer’s warranty? One will hope Isuzu fix this with the next model along with the engine bay body tearing issues.
We have same problem here of the Isuzu Dmax front tire uneven wear. Though our unit is 4x2 and using it on highways only and it is all stock parts(no upgrade nor improvement done) At 34,000km and 2years and 6months of using it,we already change the front tyres with new set for safety. We've done tyre rotation at the schedule recommended by the dealership but the problem of uneven tire wear still observed. Now that i've watched your video i am slso waiting for your update for the result of your change of steering knuckles. Thanks for this valuable info.
Why hasn't a class action been filed for this issue? Why should I pay $2,500 to fix this design problem? I am a BT50 owner and I have now chewed though 4 sets of tyres at the front, This includes a set of BF Goodrich. Mazda are trying to blame me because I have upgraded suspension. Which, I installed to counter this problem in the first place before this issue was revealed. I have evidence of wear before mods to the ute, but still no care from Mazda. I don't understand why everyone is letting these guys get away with this?
So you’ve installed a 2-3” lift GVM upgrade (with UCA’s, shocks etc), then had to install a new steering knuckle & another UCA (that’s compatible with the new steering knuckle) to fix it?
Hey Guys. Have had my MUX for a few months now...only 3k driven. Is this an issue shwoing on all Iszuzu or just sone...would you recommend me having someone look into this straight away?? Or do i need some tyre wear evidence ??
Ford FG GT's have this same problem. More so than the std FG's. Probably because they ride lower. And as far as I know nothing can be done. My mechanic told me not to do many 90 degree turns as that is what wears out the inside edge the most. ???
Hey. Are The Dmax aliminium tail shaft strong enough for offroad punishment. I dont want one small hungover and the ground breaks the shaft. Thats the opposite of why I want a dmax. I want bulletproof
Aftermarket specialised wheel alignments (not following Isuzu's factory specifications) and aftermarket upper control arms can help the issue, just not rectify it entirely. 👍
We, at Munji 4x4 Accessories, have been covering this for a long time as well with a few new developments on this issue and all the other issues relating to the rust inside the racks and excessive movement/incorrect adjustment of the rack slides. There are two much cheaper options we have to fix the bump steer.
How is the FIX going for the Bump Steer Issue?? we are about to get it done on Our Dmax. only got 15k KM out of a set of Yokahama Geolander GO15 LT tyres at over $430/each!! we have 10mm tread depth on rear and 8mm outer and 4mm Inner on front !!!! just the $3000+ price is a bit of a hit - Fulcrum.
Neither since I had this kit fitted to the dmax (in the interest of keeping my testing as accurate as possible). So those readings are for the same tyres that we're swapped from rear to front at time of the SuperPro knuckle installation. 👍
I reckon we have not had a vehicle which does not wear the front tyres excessively and, to be truthful, unacceptably, for several decades, until... We currently have a VW Amarok, previous generation, genuine VW. It is now more than 8 years old. It does not chew the front tyres out at all. Additionally, this vehicle is constant 4WD, so there is another "excuse" for dishonest manufacturers to sweep this issue of unacceptable front tyre wear "under the carpet". To me, this vehicle proved that with good design, independent front suspension 4WD vehicles should not have inherent problems with front tyre wear. I do not understand how manufacturers think they can get away with inferior (poor) design, and simply tell consumers "they all do that". We should be bringing them to account, and make them rectify their poor design.
Mate I had a 1998 Nissan GU Patrol for 23 years and had Bridgestone and Coopers tyres during its lifetime. Never had uneven wear problems. Used to rotate the tyres about every 20,000kms..
@@explorebound we are getting package installation 3200$ !! How many ks ya done since fix? Do you just swap tyres left to right or do full tyre rotation every 5000km
No. Only 3rd gen or 2020 on. Yours is 2nd gen. However: If you are smart you will replace the 2 front body mount rubbers for the RG Colorado style & fit a 1st gen or RC Colorado LSD rear diff centre particularly if you do a lot of soft sand / slippery mud driving.
This issue is affecting the current model DMAX, MUX and Mazda BT-50. Whether it's worth the investment to fix depends on how many km you plan to drive in the vehicle before upgrading. 👍
I had no real interest in this information as I own an early model Dmax. But I really wanted to commend you on an excellently presentated video. Thanks Dan and Bianca.
Did you even watch the video? He literally said 'knuckle from Superpro' (@3:10) and mentioned it was sourced/installed by the Fulcrum Suspension group, which owns Superpro.
How can an established vehicle manufacturer produce a vehicle with such a serious design problem? Ridiculous! So what else have they got wrong? Not fit for purpose, I want my money back! 😡
There was a post the other day on the 21+ DMAX/MUX facebook page anout the tyre wear issue then updated with: "Update. Can confirm that on August 31st an internal bulletin went out notifying dealerships that the factory specifications for toe in were incorrect. Previously the specification was 0mm, updated is 5mm.. considering the dealership said my alignment was “waaaay out” when they measured total toe at -3.7mm… then getting an update to say it should really be +5mm" Edit: Then seen another post about being able to take your vehicles back to Isuzu to get a free set of tyres and wheel alignmen, unsure how everyone's success will be with such claim but always worth a shot.
Yeah I did see that the other day actually! 🙂 It's my understanding that the new factory alignment specs might have a positive impact (and potentially rectify other issues too) but the bump steer issue will still throw the toe out more than normal on these vehicles - this is essentially how much the front wheels are temporarily pushed out of alignment during compression, so even with the alignment being spot on the change during those moments is the problem if that makes sense?
**TYRE WEAR UPDATE**
The rear and the front tyres have now been swapped over for an even baseline to the test - I'll update the below measurements as time goes by:
(Front tyre wear vs km since steering knuckles were installed)
0KM: Outside: 8.5mm / Inside: 8.5mm

rubber will wear quicker at start as its softer and starting to harden up alot later n wear will slow down the wear rate basically like driving with concrete tires as they get older but we wear less in the latter stages
Selling my bt50 in the morning. Dealer blamed me suggesting i was driving around corners too fast.
Mazda went backwards after parting with Ford Ranger IMHO.
Awesome Video, it was great to see this as I was researching this issue before buying a D-MAX. Looking back now have you also fitted UCAs or have found they are not needed, with addition to the steering knuckles?
Mate! I've got to say your explanation is the best! You've nailed it.
I was considering getting a D-Max and I plan to travel with it up north to Shark Bay, Karijini, see the canyon in Exmouth ...etc. I now wonder if I should still consider the D-Max or look at other utes? Cheers mate.
Thanks mate, glad the info was helpful! In my experience, nothing is perfect when it comes to cars and all models have some sort of drawback. All things considered I’m really happy with the Dmax, I’ve used mine pretty extensively over the last few years, travelling over 60,000km around WA without any issues 🙂
85,000km on my set of AT’s and still going my car must be one the few good ones 3” lift with black hawk UCA’s
Awesome info thank you very much, as a mechanic havent hurd much bad points to the dmax and bt50
It’s actually the other way around, the front tyres wear faster than rears, especially on utes where front brakes are discs and rear are drums, generally front does a greater proportion of braking
Not really, I carry constant 800kg of load and the rears wear out twice as fast as the fronts… depends on setup with tray / canopy etc
Very dependant on load and where it's placed, I personally know of guys who are chewing thru rear tyres at 30 - 40k pulling heavy trailers and if your a tradie who is in a hurry you could almost halve that
Funny you released this, ive had a lot of wear on the outside of my front 2 tyres (2017 MU-X). I do also think my increase in wheel/tyre size from factory and my 2" lift have contributed to it as i havent yet changed out my upper control arms yet. Just very interesting this is a common issue though regardless.
Interesting to hear your wear is mainly on the outside of the tyres!
Toe-in issue with yours eg incorrect wheel alignment
I would expect this to be a recall by ISUZU / Mazda, looks like a faulty part from factory, plus compensation for those that have had to replace their tyres early.
Everyone always bags out the other brands saying Dmax and Hilux are the best, they are no different they both have as many issues just like all brands.
Yep, impossible to find a vehicle that doesn't have at least one drawback nowadays I'm afraid. 👍
lol can’t believe you released this video today
Was literally talking to my mate today about this issue after lift and uca
Interesting to hear that you're still experiencing the issue with aftermarket UCAs 👍
Let’s hope the manufacturers fix this problem
Got the recall letter on Friday from Isuzu to get the knuckles replaced under warranty. 😊
Hay mate
any chance you could give me an update on the tyre wear after the steering knuckles were replaced to date
mine has done 20k km 4 wheel alignment's and front tyres are gone already
thanks keep up the good work
Pretty embarrassing when A-list brand ute has such a fundamental and critical design flaw that has to be fixed by the owner at their expense to enjoy a standard ownership experience. Just to highlight how stupid this is, I am running a GWM cannon with 50mm lift and the same tyres, no rotations after 35,000km and perfectly even wear on all 4. Never had that before in a modified 4WD, glad I didn't pay $20k more to enjoy something like this occurring! I have 9mm wear after the same kms as you on 276/65/18 version of the tyre. Measured in three places across all 4 tyres.
I wouldn't admit owning that but best of luck
Excellent analysis Daniel, very informative.
The steering arm on the knuckle looks raised about 25 to 30mm.
Lowering the rack and or moving it forwards would do the same.
My money would be moving the rack forwards to alter the ackerman geometry, those knuckles are not cheap.
I had my front tires replaced by Isuzu a couple of weeks ago, they also did a wheel alignment let’s see they go, mine is completely stock
Customer of mine came in with that story. They originally had the settings low because…. Lack of understanding i guess, then he showed me the new specs they set it at and they had jumped to putting it at risk of outside edge wear and fast too…. Seemed like halfway between would have been better
It's a good demonstration of the issue but the testing you did showed toe in, not toe out. Toe in would cause the outside of the tyres to wear prematurely, not the inside. Would have been great to see how some suspension compression altered the geometry (which is obviously what's causing the most issues). Also, I think you mean "minutes" not "seconds" when reviewing the toe angles at about 7:53 .
It's amazing that people pay big money for these Ute's and still they have faults.
Really what are you paying for.
So much to their engineers getting it right and their road test...
Imagine paying big $ for a new DMAX then having to spend another two and a half grand to get it to steer right???
Absurd. Not to mention the money already wasted on the 2 front tyres.
Then everyone walks around muttering the golden line, “you only get what you pay for”.
Ludicrous.
Does this affect stock configurations as well? Im surprised this doesn't warrant a recall.
Hard for me to say definitively as mines been modified since new, although from what I hear it does affect unmodified vehicles too, just not as badly as a vehicle that's been lifted etc.
What's the cost off fixing this problem please,my son has the 2022 model,is that affected.
Hi mate! It's $1760 for the parts or $2465 fitted (through Fulcrum Suspensions) Here's some more info: bit.ly/3EXun3T
The bump steer is incredibly evident in car I’ve only done 2000 in new BT50 and it’s like having worn bearings in front. Def factory recall should be.
I wheel align a lot of vehicles
And i also pay attention to bump steer assuming load, and these things are so crazy
But look at the angle of the steering arm/trackrod/tie rod/rack end, it points down on an aggressive slope
So as the body lowers it flattens out pushing it toe out
I’ve taken to trying to guess the bump steer when loaded and bumped
But they tend to jump double the toe amount of most other high bad bump steer cars so it’s a moving target
The worst bump steer car is still a certain Suzuki van i saw which ii had to give a wheel alignment problem just to make it straight with two people in it.
Been through 3 sets of front tyres at 32000kms. Pretty bad huh. Isuzu is "managing" the issue now (as of Aug 31st) by setting toe in to +5mm, in order to get more even wear. The dealer replaced my front 2 tyres on warranty and then aligned with new settings.
When I have some money to upgrade suspension, I'll through those knuckles on as well.
As stated by many other owners, 100% should be a recall.
+5mm: Now there's a bandaid solution from Isuzu! 🤔
Took me 6 years to fond someone that could align a dmax properly, I was having so much trouble with my 2015 dmax wheel alignment, then I ran into a mate I did my apprenticeship with, he was working at a brake and front end specialist, I asked of he could sort out my dmax, it’s the first wheel alignment I’m happy with, still getting uneven tyre wear, and other still howls around corners, and it still gets bump-steer, and it’s still a fucking piece of shit, but at least it drives straight and doesn’t wander as much…
Hi mate. How much did you pay for the steering knuckles? And also what brand it is? Cheers!
Thanks for this video Dan it was so helpful, I’m going to follow up if the upgrade affects my GVM from Pedders unless you have already checked?
Thanks mate! Regarding the GVM upgrade I wouldn't think it would be impacted by the upgrade, but I'll touch base with Pedders and report back. 🙂
Was the alignment put back to the Manufactures specs or changed.to fix the problem. Whats the original manufactures setting for the vehicle. Bump steer should wear the tyres 0n both sides of the tyre as the suspension goes up and down.
I have a 2021 BT-50, only done 28k km on the stock H/T tyres (planned to change to A/T at first change. They wore to the wire on the weekend when I was in Perth (live in Kalgoorlie), rang the dealership I purchased from to rectify. Mazda claim the bullbar fitted by arb (bought as part of the car) are at fault. Currently arguing for reimbursement for a new set of front tyres from the dealership
Good luck with GC Motors! The weight of the ARB bar particularly with winch fitted actually mask the problem NOT the other way around! Having said that & if we are being honest, the OEM H/T's never last much longer than 30K regardless. (Max I have seen is 45,000km with regular rotation, perfect tyre pressures (vs factory recommendations) etc. This has been the case on BT50/Ranger since 2013 odd (PX) Cheers
@@mjhmech4903 actually purchased the BT from a different dealership (won't name) but had a lot of back and forth arguments with the service manager over who was liable, tried to place on ARB even though my dealings with Mazda. In the end a family connection with the dealership owner had $800 transferred to my account for two new front tyres- just happened to be A/T fitted; in luck that day
@@seansmith5250 So unless you have an insider, we are all screwed!
Inside wear of thread of dmax is pain in the ass... is fulcrum the brand of steering knuckles?
Any word on whether this is the same for 2017 models. A family member has one and inner treads are wearing prematurely. They know little of its previous history though. I’m also considering buying it from them. Happy to do the mod if I’m aware upfront it’s needed.
Cost to replace the knuckle?
Thanks for the alert - I guess the elephant in the room is how it affects your manufacturer’s warranty? One will hope Isuzu fix this with the next model along with the engine bay body tearing issues.
that workshop is very clean
A pedders person told me this week that they are developing a similar product, but it's a ways off being released.
We have same problem here of the Isuzu Dmax front tire uneven wear.
Though our unit is 4x2 and using it on highways only and it is all stock parts(no upgrade nor improvement done) At 34,000km and 2years and 6months of using it,we already change the front tyres with new set for safety.
We've done tyre rotation at the schedule recommended by the dealership but the problem of uneven tire wear still observed.
Now that i've watched your video i am slso waiting for your update for the result of your change of steering knuckles.
Thanks for this valuable info.
Isuzu says they wont give me uneven tyre wear warranty if i change tyres. Gotta use their stock tyres
What is a "specialised wheel alignment" compared to a run of the mill one?
Why hasn't a class action been filed for this issue? Why should I pay $2,500 to fix this design problem? I am a BT50 owner and I have now chewed though 4 sets of tyres at the front, This includes a set of BF Goodrich. Mazda are trying to blame me because I have upgraded suspension. Which, I installed to counter this problem in the first place before this issue was revealed. I have evidence of wear before mods to the ute, but still no care from Mazda. I don't understand why everyone is letting these guys get away with this?
Is this problem with all years of MUX or just the latest models?
Hi mate just watch this video very help full but must ask are you running a drif drop and do you run a egr delete cable thanks
Hi mate, glad the video was helpful! No I'm not running a diff drop or an EGR delete cable
Shame on Isuzu for not making a better knuckle from factory . So much for R&D . My Ranger got 90K + out of the factory R/T tyres .
So you’ve installed a 2-3” lift GVM upgrade (with UCA’s, shocks etc), then had to install a new steering knuckle & another UCA (that’s compatible with the new steering knuckle) to fix it?
No, still running factory UCAs. This issue also affects vehicles with standard suspension so the suspension + gvm upgrade is independant to this.
Hey Guys. Have had my MUX for a few months now...only 3k driven. Is this an issue shwoing on all Iszuzu or just sone...would you recommend me having someone look into this straight away?? Or do i need some tyre wear evidence ??
Ford FG GT's have this same problem. More so than the std FG's. Probably because they ride lower. And as far as I know nothing can be done. My mechanic told me not to do many 90 degree turns as that is what wears out the inside edge the most. ???
I have heard BT50 are the same is that true ??
They are the same vehicle, so yes.
Hey. Are The Dmax aliminium tail shaft strong enough for offroad punishment. I dont want one small hungover and the ground breaks the shaft. Thats the opposite of why I want a dmax. I want bulletproof
Great video. What are some of the cheaper alternatives?
Aftermarket specialised wheel alignments (not following Isuzu's factory specifications) and aftermarket upper control arms can help the issue, just not rectify it entirely. 👍
Munji do over a bolt in kit (offset rack bushes) for only $176
We, at Munji 4x4 Accessories, have been covering this for a long time as well with a few new developments on this issue and all the other issues relating to the rust inside the racks and excessive movement/incorrect adjustment of the rack slides.
There are two much cheaper options we have to fix the bump steer.
Thanks for the video, but, knuckle hell, where do you get the income to be able to make so many repairs?
$2,500 well worth it, great improvement.
☝😎
Great info, we get our new MUX in the next week or so. Cheers.
How is your new MU-X going mate? Are you happy with it? Cheers
Excellent info. Cheers!
How much is the cost of the truck canopy?
Hey bro👋🏻 what’s your tyre spec? Are those R17 wheels?
Hey mate, they're 285 70 R17 Maxxis Razr AT811 tyres on 17x9 rims with +12 offset.
Around minute 6.06 your mechanic belted the abs sensor while disconnecting steering arm
I think you need to look again. He was nowhere near it.
Ive got the same issue on my 2011 D-max
Nice vid mate! Have a set on mine as well (beat to the upload lol) and have had a simlar experience 👍
hai broooo.. any update on this product so far?
How is the FIX going for the Bump Steer Issue?? we are about to get it done on Our Dmax. only got 15k KM out of a set of Yokahama Geolander GO15 LT tyres at over $430/each!! we have 10mm tread depth on rear and 8mm outer and 4mm Inner on front !!!! just the $3000+ price is a bit of a hit - Fulcrum.
It's going well, after approx 10,000kms the front tyres are now wearing mostly even (see pinned comment for exact measurements).
@@explorebound getting two new front tyres fitted and then bump steer kit fitted.
@@explorebound do you do full tyre rotation every 5000 or just swap left to right?
Neither since I had this kit fitted to the dmax (in the interest of keeping my testing as accurate as possible). So those readings are for the same tyres that we're swapped from rear to front at time of the SuperPro knuckle installation. 👍
I reckon we have not had a vehicle which does not wear the front tyres excessively and, to be truthful, unacceptably, for several decades, until... We currently have a VW Amarok, previous generation, genuine VW. It is now more than 8 years old. It does not chew the front tyres out at all. Additionally, this vehicle is constant 4WD, so there is another "excuse" for dishonest manufacturers to sweep this issue of unacceptable front tyre wear "under the carpet". To me, this vehicle proved that with good design, independent front suspension 4WD vehicles should not have inherent problems with front tyre wear.
I do not understand how manufacturers think they can get away with inferior (poor) design, and simply tell consumers "they all do that". We should be bringing them to account, and make them rectify their poor design.
Mate I had a 1998 Nissan GU Patrol for 23 years and had Bridgestone and Coopers tyres during its lifetime. Never had uneven wear problems. Used to rotate the tyres about every 20,000kms..
hey bro do yous deliver in the Philippines? cheers!
I notice ya didnt get Upper Control Arm with this mod? have you now had that installed ??
Still running the factory UCAs at this stage
@@explorebound we are getting package installation 3200$ !! How many ks ya done since fix? Do you just swap tyres left to right or do full tyre rotation every 5000km
Great vieo as always!
Is this a problem on the rg colorado series 2 I have the formula 4x4 lift tit in it scrubbing on inside same tyres as old mate on video
2015 Dmax have this issue too? still all the same front ends since 2012 model?
No. Only 3rd gen or 2020 on. Yours is 2nd gen. However: If you are smart you will replace the 2 front body mount rubbers for the RG Colorado style & fit a 1st gen or RC Colorado LSD rear diff centre particularly if you do a lot of soft sand / slippery mud driving.
The BT 50 has the same issue.
The cause extra weight on the front end the BULL BAR.
Do have a lift on this car ?.
Do all vehicles need this?
This issue is affecting the current model DMAX, MUX and Mazda BT-50. Whether it's worth the investment to fix depends on how many km you plan to drive in the vehicle before upgrading. 👍
I had no real interest in this information as I own an early model Dmax. But I really wanted to commend you on an excellently presentated video. Thanks Dan and Bianca.
Was this sponsored by SuperPro?
Do you have a 2022 Dmax ?? We run Yokahama Golander GO16 AT
Yep mines 2022 🙂
Isuzu refuses to fix my Dmax because I got 40000 out of my tyres (rotating it every 10,000). My first front tyres lasted 10000k
What brand was that steering knuckle and where can I get it..
Did you even watch the video? He literally said 'knuckle from Superpro' (@3:10) and mentioned it was sourced/installed by the Fulcrum Suspension group, which owns Superpro.
Any one know about a steering damper or stabilizer for the Mazda bt50 gen 3?😢
Where can buy?
This has to be a warranty issue.
well described.
Shouldn’t this be done under warranty?
Not much luck with warranty for this unfortunately, I think it's deemed within 'acceptable tolerences' or something similar.
How can an established vehicle manufacturer produce a vehicle with such a serious design problem? Ridiculous! So what else have they got wrong? Not fit for purpose, I want my money back! 😡
Great vid. Subscribed becuase of it
Thanks! 😀
There was a post the other day on the 21+ DMAX/MUX facebook page anout the tyre wear issue then updated with:
"Update.
Can confirm that on August 31st an internal bulletin went out notifying dealerships that the factory specifications for toe in were incorrect.
Previously the specification was 0mm, updated is 5mm.. considering the dealership said my alignment was “waaaay out” when they measured total toe at -3.7mm… then getting an update to say it should really be +5mm"
Edit:
Then seen another post about being able to take your vehicles back to Isuzu to get a free set of tyres and wheel alignmen, unsure how everyone's success will be with such claim but always worth a shot.
Yeah I did see that the other day actually! 🙂 It's my understanding that the new factory alignment specs might have a positive impact (and potentially rectify other issues too) but the bump steer issue will still throw the toe out more than normal on these vehicles - this is essentially how much the front wheels are temporarily pushed out of alignment during compression, so even with the alignment being spot on the change during those moments is the problem if that makes sense?
@@explorebound yeah gotcha, personally I feel this is still manufactoring issue and should be a recall but that's just me 😆
BS bandaid solutions. Next they will be telling you to run 60psi in the fronts!! 😆
Appalling. Should be a recall.
I feel I have seen this video somewhere else
Isuzu should fix this under the Warranty 😢.
what you takling about factory tyres man i dom with my 60.000 and they are good ..
