AMD, The main reason I would avoid the Toyota/Lexus air suspension relates directly to the fact I can't afford the Toyota/Lexus models that offer it. 😉🤣
Actually… this might provide an opportunity. Someone may be selling their GX under valued because of the air suspension problems… and swapping to coil spring isn’t that difficult. Maybe something to watch for.
Love your channel and insights you offer. I also have a 2007 gx-470. Have 305,000 miles. Already replaced rear suspension at 210,000 miles. Bought new, always changed oil every 5000 miles. Engine burns very little oil between oil changes. Original transmission. Considering I never got to 100,000 miles with a domestic vehicle, cannot say enough great things about Lexus. Just wish they had timing chain - I've replaced timing belt and water pump every 100,000 miles. Keep up the great work.
I replaced the rear airbags on our 2008 GX470 with Arnott airbags (made by Continental) at 184,000 miles after a noticeable rear sag on overnight parking. Rock Auto had best price at about $320 for a pair with free shipping plus they carry a lifetime warranty. Best to watch several videos on TH-cam to capture little tips on removal of the retaining clip and removal of the air lines at end points. Make sure you take pictures of how the air lines run. If you can change the oil on your GX, you can replace the airbags. It was about a 3 hour job as we took our time which included removal of the spare tire and both rear tires plus jack stands for safety. Back to original condition with height control and smooth/soft ride 😊
I just replaced mine in Moab after they blew on the trail. Possibly because the suspension drooped out too much. Two used bag didn't work, so I put in the Arnotts. I find them to be of better quality, and the fact that the lower cup is retained at the axle, unlike factory bags. I think the ride is a bit firmer than I had before, and much more controlled.
As someone who has been working in suspension development for over ten years and mostly on air springs I have never seen air leaking through the bellow like that and I have basically seen everything. Tells me our products are designed somewhat better with a fully closed gaiter top to bottom. Now you can run air springs without or like here an open gaiter, but sooner or later rocks and debris will be caught in the air spring and pierce the rubber. Seeing some kind of laziness on a Lexus like that looks somewhat strange. Cost for a closed gaiter may have been a dollar or more on parts price for the OEM.
at 160k miles and 15 years I would replace all suspension rubber parts as a matter of preventative maintenance along with checking/replacing the shocks My local mechanic thought I was a little OTT until he experienced the before andf after difference in handling Parts which looked ok on the car such as swaybar mounts showed their wear and how the bar clamping holes enlarged over time when compared to the new parts
The air bags for the rear suspension are not all that expensive. But four shock absorbers, rear axle seal, parking brake, front right wheel bearing, the looseness in the front suspension, leaky transfer case, and whatever issues, including the possibility of replacing the timing belt and water pump are found in the engine bay are going to make for a hefty repair bill. Oh, and add in the cost of four new tires. Still, if the vehicle is in good condition otherwise, it's worth it when one considers the price of a new one and the cost of the insurance premium.
True. This past summer we dropped $4k on our 2013 Highlander limited w/ 150,000 miles. It needed pads and rotors and struts all the way around. Thanks to AMD’s videos I was able to discuss the stated repairs intelligently with the technician, not just the service writer. He sent me picks of our issues. And, yes, I knew it was of our Highlander because I had crawled under it often enough for oil changes to know it was ours. 😊 In this case it didn’t save me money but did provide peace of mind that what needed repair was repaired. 👍
You can really tell when someone is not just says they are a believer in god but are truly trying to live it’s meaning to the best of there ability and it definitely reflects in his personality and blessings
recently bought a hybrid corolla and was told by the dealer use only the electronic corrosion system offer by the dealer. Told not to use spray rust proof because the battery is a the bottom of the car and wax of any other spray will cause issues with the battery and would void the warranty. Your comment is greatly appreciated
He is a master mechanic with a wealth of knowledge. I have gotten so much bad advice and bad repairs from both dealers and "mechanics" that it is very refreshing to view his videos.
Ah,yes. Mercedes-Benz air suspension. Incorporated an alcohol cannister back in the day (70's) to scrub the condensation water out of the compressed air and prevent premature failure. Also, there was a user serviceable relief valve to dump accumulated condensation that most owners ignored completely. The troubles surfaced far sooner than those on your subject car. We sold many conversion kits to retrofit with steel springs. SO, M-B decided that oleo-struts would be more reliable and starting in the late seventies gave us five metal spheres, divided into hemispheres separating oil from nitrogen, one for each wheel and one maintain ride height, plumbed into the rear struts. By the early eighties the separation bladders were failing and usually required replacement of all five. At a $1000 each. And they wonder why Lexus sales took off like a rocket in the next decade.......
Please do an advise video on how to find (and screen for) an honest mechanic. What to look for, questions to ask, red flags. Love the channel, may The Lord bless you and keep you.
My GX470 rear airbags went out. While on a road trip. Something like $1200 to fix. My next GX 460, I went out of my way to get the rear steel coil springs option.
I like your tip about hitting the tire to listen for abnormalities in the suspension components. I only wished that I had seen the video about two hours sooner and I could tried it out on my LS430...
Wow. What a coincidence that I'm just getting home from replacing the complete rear air suspension on a 2009 GX470 and AMD comes out with this video. What he says is true. It's not a scary job to get into.
Love my 06GX. It had a lot of the issues listed in this video, all rather easy to remedy and quite affordable, especially if you do a lot of the work yourself.
I still have an '06 Range Rover Sport with full air suspension. I had to replace the rears @ 150k miles. But I just learned more about air suspension from your video than anywhere else. LOL. (Our other vehicles are Toyotas.) I wished your shop was in my area.
I installed rear air bags in my 4th gen 2006 4runner in 2008. I Bought the firestone kit that you install one bag inside each coil, run the air lines how and where you want them, put in air gauges. They have worked perfectly all these years. I did not even install auto air pump compressors. Manual or small air pump as needed for the load. Large load never exceeded 28-30 lbs. no load run about 5-8 lbs. lifetime warranty. Love them and recommend them. Cost about 200 bucks for everything.
I added a set of Firestone Air-Lift bags to the rear of my 2007 Tundra, they are used to firm up the rear suspension and prevent sagging when hauling a heavy load or towing. Leaf springs, air-bags and shocks keep the rear planted to the road.
Can you do a video on the LX air suspension as well? I know some older models had a hydro-pneumatic suspension rather than full air suspension. It would be interesting to see and learn about it as well. Especially important maintenance and such.
150,000 miles on my ‘08 GX470. Rear end would sag overnight. Could still drive it because it would refill in 2-3 minutes. I replaced them myself in about 2 1/2 hours. Turned out to be pretty easy. The airbags were around $250 from Rock Auto.
I appreciate all of the wonderful videos you shared. I'm a do-it-yourselfer who finds mechanical repair to be incredibly enjoyable. I own a 2014 Sienna XLE, with 135K miles on it, in Las Vegas, Nevada. I am having trouble finding the answers to two issues. 1. I have no problems with my sliding doors. Any button on the car or remote can be used to open and close them. When I attempt to open the passenger side, it hesitates for a moment, whereas the driver's side opens instantly. 2. The heater blows far colder air in the winter than it should. I'm not sure if that only applies to the driver's side. To warm up the car's interior, I have to run the heat at maximum. It doesn't happen all the time. If someone else has the same problem and could help, that would be greatly appreciated. Many thanks.
Just had to have my compressor on my 14 LS F-Sport done at an indy shop at a cost of almost $3600. I knew when I bought it last year there was a risk of expensive suspension issues. the shop said overall they don't see too many issues on them (they are a Toyota/Lexus specialty place). I did some reading while waiting for the part to come in to see if there was any sort of TSB etc and the one thing I read was due to the different grill on the F-Sport it made it a bit more likely that water could get into the compressor and cause it to fail. The new ones have been upgraded to address that issue and hopefully it lasts the rest of its life as I intend to keep it quite a while. Have 131k miles on it now which is just past the break in period on a LS.
Crazy timing with this video. My 470’s air compressor just went out and I am swapping to coils. Plus a bunch of other repairs. Thanks for the tip about the rear axle leak. I noticed a small leak on my driver side
Thank you for teaching me how to better take care of my cars. I also feel more confident when speaking with my dealership service center. They do try to slide stuff past from time to time. There needs to be a place like yours out here! Thanks again for the great videos.
I love air suspension. serves its purpose, properly maintained ive driven my audi a8l daily and hard for 10 years the air suspension has held up great only had an issue with a rear strut which was reasonable to replace
Great video and info as usual AMD. Sad to see the amount of rust on this GX. But being from the rust belt I am not all that surprised. I just hoped Toyota would have better undercarriage paint and rust proofing than what they currently offer. I caught the rust on my 2019 GX (second owner) before it progressed and now I spray it annually just to keep it at bay. I wish if the previous owners did the same when they bought it new..
I've done this on an old GX but wound up going with the $100 chinese units that lasted for a few years without any issues. Took me about 2-3 hours to replace diy. Lexus wanted $800+ for each air bag on a truck with high mileage
Idk if he noticed, but axle seal was leaking too... we find this to be common in the UK with it being more humid here than across the pond. Breather on top of the axle corrodes and cannot let air in and out which when it gets hot and pressurises it pushes the oil out the axle seal. Always more common on the left than the right - idk why!
Driving class 8 trucks for years with air ride and understanding the system. I rather have air bag over spring any time to me they're just as easy to fix as coils.
I have learnt the lesson hard way. Bought my LS 460L when it was 3 years old in 2018. Rarely drove that car because I had a better LS 430. One day during the 2020 pandemic, the front driver strut failed and the car was limped to that side. $1300 fix!! My trip was disrupted because dealer was scrambling to get the part. LS potential buyers beware! There are 4 air struts and one height compressor. If the latter breaks, it is going to be $3000. Don't cheap out from fixing an air strut, because this puts stress on the compressor to pump and pump and pump until one day it is fed up!
Driving an almost 19 years old Hilux aggressively, including off-roading once in a while I can vow that Toyota has a very dependable suspensions. Just the necessary shock absorber replacements with one upper ball joint replacemet which I doubt was necessary as I didn't feel any loose suspension. Excuse was, alignment couldn't be done without the replacement. Even the bushes are still original.😮
Mechanical springs provide resistive force proportional to (up-down) wheel movement (F=kX), so large bumps get large resisting forces. Air springs compress an air cavity which reacts with a virtually constant supporting force regardless of wheel position, so it's much softer--but doesn't handle as well.
Can you please do a video on AHC sensors? How and why to adjust the arm up or down? My 04 GX passenger side rear is 1 inch higher than driver side. And no matter what I do, the difference is not going away. I changed the airbags, AHC sensors, still no luck. A video on AHC sensors would be very beneficial to this community. Thank you!
YOU GOT ALOT DONE! Garage was overwhelming last time! I feel bad for this customer, alot needs done. If I were the owner, I'd ask u to give me a list, PRIORITY WISE, and begin a plan. Thats great u noticed all that. When I had a 97 Camry & my garage did my state inspections or ANY jobs, I said if u see anything, let me know. I may have not got fixed that day, but as soon as I could, I had them do. I'd use coils, w/new shocks all around. Tires would be last until all suspension fixed. Then an alignment.
Hello AMD. Great video as always. Owned a 2018 GX 460 w/o air suspension and now a 2022. Love it. The KDSS light came on and dealer said the code shows a leak. It makes a clunk sound over bumps on the left side. Is this an expensive repair? I never had an issue with my last GX. Keep up the great work! God bless you and your family.
Mr. Amd, would you be willing to review the new Nissan Pathfinder since you did the Pilot. I and I’m sure many people are split between those two. Btw you are hands down the best reviewer on TH-cam. Thank you for your hard work and unbeatable knowledge. 💪
I know ls400 and gs/aristo's that still have the original 1990's air suspension without any service done to them and are riding great. They can be made reliable, and they can also still be cheap by the time they go bad, just don't park in the heat if you can avoid it and dress/coat your rubbers.
Thank you for posting this excellent video. The more I watch this channel. the more I wish I had my own private car lift in my outdoor parking space so I can inspect my vehicle's chassis every week. Perhaps it is just a bit of fantasy on my part...I am not a qualified automotive technician. But I can wish for the lift.
I love the air suspension on my 07 MB GL320 for towing, but I have changed out the rear bags and front air springs with Arnott’s. I will see how the lifetime warranty works because the front passenger side is starting to sag after sitting overnight. I believe I changed that one out 7 years ago.
I love your channel! We have a 2004 GX470 with only 76k miles on it. The best vehicle we have ever owned we bought it new for 52k and it is 20 years old now 😳 We keep up with oil changes etc. We have only had to do brakes, and because we lived in Chicago before moving to SoCal 7 years ago….we had a rusty radiator and water pump. It still rides perfectly and we do mountain driving for skiing. If I was still in Chicago I would definitely go to you…my mother grew up in Park Ridge. I found a pretty good independent mechanic, also worked for Lexus/Toyota for ten years. It was funny because the first time I brought my SUV in he asked where I was from. Mechanics in SoCal don’t see much rust 🤣 It’s not bad, and always been garage kept…but the salted streets do create surface rust and sometimes difficult bolts! I had to go to a mechanic to change my license plates when we moved here 7 years ago….they were rusted on….new bolts then no problem. 😊
Thanks a lot Ahmed Good advise in how to test the air suspension because i have a range rover Here in dubai we have the same lexus GX with the v8 engine and we have almost the same shape toyota prado and it comes with the 4 cylinder engine (2.7) and the optional v6 petrol engine (4.0) By the way the lexus you showed has a lot of corrosion and if this car in dubai it will definitely fail the yearly test.
I love the "hands on" inspection for the suspension. Really helps me understand what's going on. Also..I would love to see you do a video on that Highlander. I have one and like getting in depth with that car. Thanks for the great content!
I bought my GX back in 2007. I am the original loaner best car I’ve ever had I keep it in the garage and maybe it got 93,000 miles original nobody but Lexus touches it. I wish that you were closer to where I am on the East Coast Would definitely without a doubt bring my vehicle to you for sure anyway, regarding the air suspension may be a little bit paranoid but every time I bring it in for an oil change, etc. I asked them to please check the air suspension because I’ve heard so many not so great things that I am afraid it’s going to catch up with me someday but I am hoping for the best regarding the rust under that vehicle it does seem like a lot. I guess I don’t have that due to the fact that my car is basically in the garage and if it’s snow, I don’t take it out pretty much if it rains I don’t take it out I’m just in love with it…lol😂😂
I don't see any repairs on early GX460s. It would be nice, if you could create some content on camtower leak repair, if you get a chance. Hints for DIYers are very welcome :)
my mb w211. from germany, not usa. have air spring on the back. and I love it. very stabil when It is loaded. soft. but still good in turns. But it do last about 160 000 miles. just to say. the spring lasted 240 000 mile. in the front. not too bad price aroud 1200 to replace. or you can do it your self- and you have a great ride for the next 160 000 miles.
How good is your timing on this issue. I have a 2003 4Runner Limited, V8 full time 4WD. It has the air suspension. It was replaced by the previous owner, about 8 years ago. I have no dash light on, but my OBD2 BlueDriver yielded a code that indicates that the Exhaust valve for the Height Control system is not working. I now know something about this system, and I will look in to it.
Man I wish that that GX470 didn't have those air suspension. Wish the owner consider air bag delete kit with reasonable setup like Ironman FCP front and back. I absolutely love to see standard swaybars, not having to deal with another type of leak especially seeing the amount of rust I see there. Speaking more about GX470, does the 470 have full fuel tank skid standard or an option like the 460?
Great video. I already know I'm in for a wheel bearing on my v8 4runner, guess ai better check the bushings while I'm in there. So far, so good with rear air suspension...210k miles. On the other hand, not looking forward to future air suspension issues on my wife's LS 460. I knew it was the most likely big ticket repair when we bought the car, but she fell in love with the dang f-sport version...
Because heat and ozone deteriorate rubber, IMHO, it would be best to replace all rubber items -- bushings (as for shocks, need to replace the entire shock), timing belts, seals, hoses -- at the 12 year mark, regardless of mileage. And tires should be replaced -- at the max (if not sooner) -- every six years, regardless if they are worn out or not. Just good preventative maintenance if you want to keep your car a long time. Besides, it will keep Mr. Car Nut employed, which makes Mrs. Car Nut very happy.

Why
@@brucelee5465cause he's a broke boy 😂
Understandable, have a nice day. 🗿👍
Funds aside, I think I'd avoid any car from any manufacturer with air suspension. Looks like a headache.
Actually… this might provide an opportunity. Someone may be selling their GX under valued because of the air suspension problems… and swapping to coil spring isn’t that difficult. Maybe something to watch for.
For a 15 year old truck it is pretty amazing it lasted this long considering the owner neglected to keep up with maintenance.

Parts which looked ok on the car such as swaybar mounts showed their wear and how the bar clamping holes enlarged over time when compared to the new parts

Could you do some regular maintenance videos on the GX, such as lubing the propeller shafts etc...
your knowledge always amazes me...wish you were closer
You're such a great mechanic, your should come up with an academy for young mechanics.
Keep it up boss
Turbos, superchargers and any adjustable suspensions are worth avoiding if you're looking for reliability, longevity and reasonable maintenance costs.
Very helpful. I just got an older LX and this helped answer many of my questions about the air suspension system

My 2004 GX with 246k miles still has the original rear airbags. They occasionally bleed down when it sits a few days but they always reinflate 👍🏻
Please hope to see more videos on the GX if you get to do all the repairs.
I bought gx470 used, the first thing I did, I installed ironman 4x4 suspension kit
Our 2005 Sequoia Ltd has air suspension, which is great for towing an aligning the trailer.
I'm looking to purchase a GX470 and this is really helpful, thank you

No frigen air suspension ever in my cars. too many things to fail. A solid metal coil rarely fails.
I love you AMD ❤ for many reasons. But probably most importantly for your unbiased professional opinions. Helps us weekend worriors greatly!!!

I just hoped Toyota would have better undercarriage paint and rust proofing than what they currently offer. I caught the rust on my 2019 GX (second owner) before it progressed and now I spray it annually just to keep it at bay. I wish if the previous owners did the same when they bought it new..
Like the tours of the shop.
I've done this on an old GX but wound up going with the $100 chinese units that lasted for a few years without any issues. Took me about 2-3 hours to replace diy. Lexus wanted $800+ for each air bag on a truck with high mileage
Idk if he noticed, but axle seal was leaking too... we find this to be common in the UK with it being more humid here than across the pond. Breather on top of the axle corrodes and cannot let air in and out which when it gets hot and pressurises it pushes the oil out the axle seal. Always more common on the left than the right - idk why!
Driving class 8 trucks for years with air ride and understanding the system. I rather have air bag over spring any time to me they're just as easy to fix as coils.
I have an 06 Sequoia with 186k miles. I think it still on the original air suspension
converted my old ls430 to spring and shock. at the time they were 1500 each corner. so it was a no brainer to swap to traditional shock and spring.
I have learnt the lesson hard way. Bought my LS 460L when it was 3 years old in 2018. Rarely drove that car because I had a better LS 430. One day during the 2020 pandemic, the front driver strut failed and the car was limped to that side. $1300 fix!! My trip was disrupted because dealer was scrambling to get the part. LS potential buyers beware! There are 4 air struts and one height compressor. If the latter breaks, it is going to be $3000. Don't cheap out from fixing an air strut, because this puts stress on the compressor to pump and pump and pump until one day it is fed up!
Driving an almost 19 years old Hilux aggressively, including off-roading once in a while I can vow that Toyota has a very dependable suspensions. Just the necessary shock absorber replacements with one upper ball joint replacemet which I doubt was necessary as I didn't feel any loose suspension. Excuse was, alignment couldn't be done without the replacement. Even the bushes are still original.😮
Mechanical springs provide resistive force proportional to (up-down) wheel movement (F=kX), so large bumps get large resisting forces. Air springs compress an air cavity which reacts with a virtually constant supporting force regardless of wheel position, so it's much softer--but doesn't handle as well.
Can you please do a video on AHC sensors? How and why to adjust the arm up or down? My 04 GX passenger side rear is 1 inch higher than driver side. And no matter what I do, the difference is not going away. I changed the airbags, AHC sensors, still no luck. A video on AHC sensors would be very beneficial to this community. Thank you!
YOU GOT ALOT DONE! Garage was overwhelming last time! I feel bad for this customer, alot needs done. If I were the owner, I'd ask u to give me a list, PRIORITY WISE, and begin a plan. Thats great u noticed all that. When I had a 97 Camry & my garage did my state inspections or ANY jobs, I said if u see anything, let me know. I may have not got fixed that day, but as soon as I could, I had them do. I'd use coils, w/new shocks all around. Tires would be last until all suspension fixed. Then an alignment.
AMD, would love to see more GX460 repair videos!
Another great video and we all learn so much from the Expert. Thanks and keep up the good work.
My 2021 Sequoia Platinum has rear air suspension, rides much better than normal Sequoia
Hello AMD. Great video as always. Owned a 2018 GX 460 w/o air suspension and now a 2022. Love it. The KDSS light came on and dealer said the code shows a leak. It makes a clunk sound over bumps on the left side. Is this an expensive repair? I never had an issue with my last GX. Keep up the great work! God bless you and your family.
Mr. Amd, would you be willing to review the new Nissan Pathfinder since you did the Pilot. I and I’m sure many people are split between those two. Btw you are hands down the best reviewer on TH-cam. Thank you for your hard work and unbeatable knowledge. 💪
I know ls400 and gs/aristo's that still have the original 1990's air suspension without any service done to them and are riding great. They can be made reliable, and they can also still be cheap by the time they go bad, just don't park in the heat if you can avoid it and dress/coat your rubbers.
Love this walk around real time assessment. Obviously so experienced and knowledgeable. 👍👍
Thank you, I learned a lot about suspension, excellent 😮
Thank you for posting this excellent video. The more I watch this channel. the more I wish I had my own private car lift in my outdoor parking space so I can inspect my vehicle's chassis every week. Perhaps it is just a bit of fantasy on my part...I am not a qualified automotive technician. But I can wish for the lift.
I love the air suspension on my 07 MB GL320 for towing, but I have changed out the rear bags and front air springs with Arnott’s.
I will see how the lifetime warranty works because the front passenger side is starting to sag after sitting overnight. I believe I changed that one out 7 years ago.
I love your channel! We have a 2004 GX470 with only 76k miles on it. The best vehicle we have ever owned we bought it new for 52k and it is 20 years old now 😳
We keep up with oil changes etc. We have only had to do brakes, and because we lived in Chicago before moving to SoCal 7 years ago….we had a rusty radiator and water pump. It still rides perfectly and we do mountain driving for skiing. If I was still in Chicago I would definitely go to you…my mother grew up in Park Ridge. I found a pretty good independent mechanic, also worked for Lexus/Toyota for ten years.
It was funny because the first time I brought my SUV in he asked where I was from. Mechanics in SoCal don’t see much rust 🤣
It’s not bad, and always been garage kept…but the salted streets do create surface rust and sometimes difficult bolts!
I had to go to a mechanic to change my license plates when we moved here 7 years ago….they were rusted on….new bolts then no problem. 😊
Thank you for a very compact, informative and concise video on the GX.
Much appreciated from a solid DIYer 🙏
Thanks a lot Ahmed
Good advise in how to test the air suspension because i have a range rover
Here in dubai we have the same lexus GX with the v8 engine and we have almost the same shape toyota prado and it comes with the 4 cylinder engine (2.7) and the optional v6 petrol engine (4.0)
By the way the lexus you showed has a lot of corrosion and if this car in dubai it will definitely fail the yearly test.
I was hoping for coverage on the LX470, 570 & 600 AHC suspension system while you're at it, one of these days you could cover that too. Thanks!!
Do all 2017 GXs have air suspension or just the luxury trim? Do LXs have air or hydraulic suspension?
I love the "hands on" inspection for the suspension. Really helps me understand what's going on. Also..I would love to see you do a video on that Highlander. I have one and like getting in depth with that car. Thanks for the great content!
I bought my GX back in 2007. I am the original loaner best car I’ve ever had I keep it in the garage and maybe it got 93,000 miles original nobody but Lexus touches it. I wish that you were closer to where I am on the East Coast Would definitely without a doubt bring my vehicle to you for sure anyway, regarding the air suspension may be a little bit paranoid but every time I bring it in for an oil change, etc. I asked them to please check the air suspension because I’ve heard so many not so great things that I am afraid it’s going to catch up with me someday but I am hoping for the best regarding the rust under that vehicle it does seem like a lot. I guess I don’t have that due to the fact that my car is basically in the garage and if it’s snow, I don’t take it out pretty much if it rains I don’t take it out I’m just in love with it…lol😂😂
All that great knowledge, but I’m surprised to not hear at least a mention of the lower ball joints.
can any preservative be sprayed on those air bags to make them less susceptible to cracking ? Just curious
I don't see any repairs on early GX460s. It would be nice, if you could create some content on camtower leak repair, if you get a chance. Hints for DIYers are very welcome :)
This Garage must be a movie set, I have never seen a shop that clean...ha ha!
Love the GX content, thank you.
my mb w211. from germany, not usa. have air spring on the back. and I love it. very stabil when It is loaded. soft. but still good in turns. But it do last about 160 000 miles. just to say. the spring lasted 240 000 mile. in the front. not too bad price aroud 1200 to replace. or you can do it your self- and you have a great ride for the next 160 000 miles.
I learned something new. Thanks
I also got the height sensors free . They move properly
Would like to see step by step videos as you tackle each of these repairs.
What’s your opinion on those aftermarket air suspension bags that are installed inside of the coils?
Is this the best of both worlds?
How good is your timing on this issue. I have a 2003 4Runner Limited, V8 full time 4WD. It has the air suspension. It was replaced by the previous owner, about 8 years ago. I have no dash light on, but my OBD2 BlueDriver yielded a code that indicates that the Exhaust valve for the Height Control system is not working. I now know something about this system, and I will look in to it.
my 08 4Runner had 300.000kms when i sold it and then rear air suspsion was workng flawseley
Thank you for very interesting and informative video, as usual 😊
Thanks!
Good info. This looks like the same system on my 2020 Toyota Sequoia Platinum.
Another great, informative video Amd! Missed the cool intro music and title graphic!
Man I wish that that GX470 didn't have those air suspension. Wish the owner consider air bag delete kit with reasonable setup like Ironman FCP front and back. I absolutely love to see standard swaybars, not having to deal with another type of leak especially seeing the amount of rust I see there. Speaking more about GX470, does the 470 have full fuel tank skid standard or an option like the 460?
Its so easy to dump the air bags for springs no biggie.
knew a guy who had a bentley with computer controlled air suspension, front right suspension failed= $4000 repair !
Range Rover too
I've got 280k on my 2003 GX and have had no issues
“Finest aftermarket… stuff…. that’s ok” 😂
Great content time and time again. Really enjoy your channel 😎.
Great video. I already know I'm in for a wheel bearing on my v8 4runner, guess ai better check the bushings while I'm in there. So far, so good with rear air suspension...210k miles.
On the other hand, not looking forward to future air suspension issues on my wife's LS 460. I knew it was the most likely big ticket repair when we bought the car, but she fell in love with the dang f-sport version...
Because heat and ozone deteriorate rubber, IMHO, it would be best to replace all rubber items -- bushings (as for shocks, need to replace the entire shock), timing belts, seals, hoses -- at the 12 year mark, regardless of mileage. And tires should be replaced -- at the max (if not sooner) -- every six years, regardless if they are worn out or not. Just good preventative maintenance if you want to keep your car a long time. Besides, it will keep Mr. Car Nut employed, which makes Mrs. Car Nut very happy.
So question for you sir
What actually kills the wheel bearings on Toyota's/ Lexus SUV?
I don’t live in the rust belt, these rusted undercarriages are shocking every time i see them
Me too!
This guy is the Toyota mechanic goat
