I am a retired millwright of over 30 years. I bought a stethoscope from snap on within my first year. They are so so useful. Diagnosed many issues without the just replace or break everything down method. Great for really ANY tool box.
I recently watched a documentary on the huge VW plant in Germany. They used to use stethoscopes to listen to the machinery and the engineers were so in tune with their machines they could hear worn components before they failed most of the time. But nowadays they use a kind of microphone/camera that tracks the exact frequencies of all moving parts. It just sits there like a cctv cam and blinks red when some thing is wrong, you can simply zoom in on the images and it'll highlight the broken part. 300 thousand euros per microphone set up. Imagine having that technology at your finger tips! I bet before I'm dead It'll just be an app on your phone
Pro tip: when diagnosing a wheel bearing, place your hand on the coil spring and spin the wheel by hand. If it feels gritty you've found your bad bearing.
😮 I’ll need to try this one out defo 😁 im reasonably certain it’s left rear as the noise is defo coming from left side u hear it easily when you drive it close to buildings and walls etc with the windows open thts how I first noticed the noise 👍
I have never diagnosed it with that method. I usually put the transmission in neutral, lift vehicle above the ground, hold on to coil spring with one hand spin the tire with other hand. If I feel some sort of vibration in the coil spring, I would suspect that particular wheel bearing is bad.
@@angelcelis9090 think about it. The coil spring is attached to the strut, which is bolted directly to the hub carrier with the bearing in it. Any vibration from a damaged roller/ball bearing and or race would be felt in the spring. One could easily feel the same vibration in the control arm as well. I chose to mention the coil spring because anyone with a floor jack could easily do this method. One could also use the floor jack and crawl on the ground and grab the control arm and spin the tire. All I can say is try it. If it doesn’t work for you or find an easier method, then do that.
@@angelomoussignac3716 replacing a hub is quite simple and not expensive at all unless you’re driving an expensive car. Typically its recommended to replace both on the axel so you can have the same quality on both wheels.
Everyone is hating on them for using this method to find what is said to be easy to hear and find. Well, maybe, someone might see this and realize it's a great way to pinpoint noises in all kinds of locations.
I bloody love it, had an issue last week and couldn't figure if it was left or right wheel bearing on a road test, ended up pulling left side off and it was fine, on further inspection of the tyres they had wee lumps in the tread on both rear wheels but worse on left that's why it could be heard on both. But doing this would have save all that mucking around.
I can't tell you how many times someone brought in their car for a wheel bearing for it to be a transmission, transfer case, differential, etc noise instead. Just broke the bad news to a chick today that her Tcase was shot. She was not happy but grateful we didn't throw a bearing in and boot her out the door.
I been doing this a VERY long time, the stethoscope works but so does a long screwdriver, just put your ear to it and you hear everything 👍 I told a friend of mine about that trick so he used it to find a noise in his ac compressor except he put the screwdriver on the ac clutch put his ear to it AND IT CYCLED ON💥👂 needless to say he got punched in the ear by a flathead lol
I just finish changing my wheel bearings without those lift and equipment. I drove it and listened where the humming noise coming from and change it .Now all quite drive .First time I did it myself.
I've never actually used a stethoscope I always use my 2 foot long door trim fastener tool. It works just the same instead of having the buds in your ears you put the handle up to your ear and press firmly. This also works well with an extra long screw driver.
You could hear what side just from the camera. Front is easier as bearing noise gets louder or quiter turning left to right. If it gets louder turning left, you loaded the right side and know its the right.
Huh? That seems like common sense but I keep reading almost everywhere that because of the differential, if the noise gets louder when turning left & quiets when straight or right, it's the left bearing. If it gets louder turning right & quiets when you straighten it go left, it's the right bearing.
First the top to bottom wobble test, second spin the wheel by hand & grab the spring, you will feel if it's bad. No lift needed, most of the time the wobble test confirms though.
You can normally tell when going around a bend. If your bearing makes noise going around a right bend, your left bearing is bad. Vice versa also applies. This is because when turning, the weight shifts to the other side of the car.
You got that right. It's easiest that way by doing a road test first doing left and right turns. It shows up faster because the weight of the vehicle magnifies the growling sounds on each wheel bearing. Easy pickings.
Pro tip if you just jack up the tire from the lower control arm then alternate pushing on the top and pulling on the bottom of the tire as well as left and right. If the wheel rocks a little, makes a clicking or clunking sound...you gotta bad wheel bearing so go ahead and replace both driver side and passenger side hubs....
I have one of those "stethascopes" for listening to car noises, but I don't use it that often. Most things I can just hear on their own. It is a good tool though, you can find things you can't normally hear with that thing.
It's really difficult to find out a faulty bearing while driving bcoz sometimes right bearing shows the sound from left side and rear bearing sounds also puzzles. Your method is right.
My diesel instructor showed us there is many things that can be diagnosed with a broom handle and your ear Most commonly i use it to hear if fuel injectors are working so i can diagnose clogged injectors vs electrical
Standing on your head while clapping your hands and jumping up and down at the same time is a whole lot easier, best way I've found to diagnose a non faulty wheel bearing.
I love those things. A Lot of people talk shit about them,but if used properly it'll let you know if a bearing is going bad before it actually fails!!!!
I once watched someone diagnose a wheel bearing noise as a transmission output shaft bearing noise. All it would have taken was was a stethoscope to save the shop 8 hours in labor.
Mine sounds like a motor boat or prop plane at the right front wheel. I rotated tires myself and sound is still there. Changes pitch as I speed up or slow down. I can also feel vibration in the steering wheel. Maybe 1/16th play at 12 and 6 when I jacked it up and shook the wheel. I just received the Hub Bearing from Amazon and I'll replace it soon in my front yard.
another way to just figure it out is by simply spinning the wheel and then listening for noise. and then you can do a full shake of the wheel itself to figure hub and tie rods. left right is toe rod, up down is hub. spinning wheel and hearing noise is also hub.
Mechanics are just doctors for automobiles. We diagnose, we order parts, we perform surgery on the car using new parts, we do post op checks and tests, we right up a summary with the bill attached. What did I miss?
I haven’t taken it off and replaced it yet so take this with a pinch of salt, but I think the best way to tell while driving is: pay attention on bends and slopes. If you’re going up a hill and it’s louder, it’s at the rear. Down a hill and it’s louder, it’s the front. If you’re turning right and it gets louder, it’s on the left. Turn left and it gets louder, it’s on the right. Likewise if it’s louder while you’re braking or decelerating, it’s also at the front. Whenever the most weight is on the wheel with the bad bearing, you’ll hear it at its loudest. For me the sound only shows up beyond 25mph.
You can do this an alternative way by simply pushing and pulling against the wheel and if you get play that usually indicates the bearing is knackered.
I'm guessing it's just to confirm it's definitely the bearing because it's one bitch of a job. If it didn't make noise, then it's the cv joint or something else, and they can skip changing the bearing.
Extra work would be replacing the one you THINK is bad, only to discover it's the other side. Bearings are extremely hard to pinpoint which side is bad. This tool eliminates guess work... If you wanna call that "extra" work, don't come near my cars.
Dang i coulda used that method earlier to check my new (technically old) ranger i got the other day. One was bad so i ended up changing all of them anyways. Ig i got new bearings out of it lol
Noah, you get the wheels off the ground ,spin the wheels one at a time while grabbing onto the coil spring. If the bearing is bad, you’ll feel it in the spring
@@noaht5191 its easy grab the coil and spin the wheel if you feel any vibration, the wheelbearing is faulty and need to be replaced. The vibration fealt from a faulty bearing is very noticible
Not necessarily. My rear wheel bearing is going out and it only makes noise i can hear over 35mph. So doing a shake down by hand doesnt show the side thats grinding. This actually helps a lot.
My wheel bearing is making a creaking popping noise. At the beginning of this video, I can hear the same noise, except mine is louder. Probably because of the weight of the truck on it. Similar to a CV joint clicking. I bought the new hub assembly, and as soon as the rain stops here, I will be installing it. Thought I'd share my symptoms in case someone else is experiencing the same problem. 👍
Update, the wheel bearing hub assembly solved the problem. It was pretty dried up of grease inside the bearings. Will need to get one for the other side soon probably. I thought I was going to need a torx bit socket to remove the caliper bolts 🔩 but it had standard hex bolts like 13 or 15 mm. For some reason, they have a different part number for the driver's side and passenger side. You need the hub with the slotted disc for anti-lock brakes (all-wheel ABS) if your truck has 4 wheel ABS.
You don't need that tool to find a bad wheel bearing, and the second thing is it doesn't matter which wheel bearings bad you should replace both of them.
The issue is with the customer. Around here bearing replacements can cost $1000+ per side. If the customer refuses to do both then they can just find a shop that'll do the single side. That's why most shops will only do 1
When the do that you feeling vibration on the spring when you hold it and spin the tyre? Because I have that symptoms and I don't feel any vibration at the same time on the spring! Thank you
Car on axle stands. Use piece of timber against one tyre to stop rotation so diff powers other one. Repeat for each side and noisy one will be obvious.
Much simpler way, lift your car and try to push wheel in and out, if its moving it mean your bearing is bad. Also check your suspension for movement, for sure just spin wheel by hand.
I've done this many times over the years when I used to work on cars. Trying to figure out what wheel bearing to be 100% sure of can be hard otherwise. You want to make sure you did the right one. If you do the wrong one and it's not fixed, not you have to eat that job and do the right one. Now you're losing money. You're also making sure it's ot the CV Axel. Generally th eouter one will make a poppng noise when turning, but the inner one can be harder to figure out if that is the noise. If the brearing is not maing any noise, is could be the axel. If the boot is ripped and it's been throwing grease out of it for a while, that would be a big clue. Sounds can really trick you when driving a car trying tohear the noise and you think it's coming from the Right Front and it's the Right Rear. The customer is telling you it is making a noise from someplace but it's someplace else. If it's making any noise at all. The number of times I went out on a test drive and let the customer drive because I couldn't hear what they were talking about, and yet it makes no noise when I'm sitting there and they're driving,.... You can start just ramdomly looking around the car trying to find something. But using a Stethoscope on a car is something I did all the time;. I figure this is a normal thing most all Mechanics do. I still do it, but I'ma Mantenance manager for a food factory and so will use one on one of the Insutrial machines to an exhaust vent to head if it's making any noise. If that is the issue or not. Noise does travel and so you check both sides, and make sure you have the right one. There are rare times that both sides are bad, but one is worse than the other.
@@notonyt7339 I can tell you I've had loads of bent rims that weren't cracked-look at the rim bouncing-its out of round therefore bent-this will cause tremendous wear on a bearing-try taping a weight on a single fan blade and turning it on high and see how long it lasts
@@mungaloyd1 Every time I've had issues with alloy, its cracked. Just looked into it though, and you're absolutely right. They do bend. I always thought alloy only cracked, but ya learn something new everyday :)
@@scottbaldwin4654 you can turn them, but you will not feel much vibration in the coils since they're not going to be turning fast, as you're trying to back drive the AWD system which will decelerate it, it might be easier on some cars, but on my Subaru it wouldn't be possible to use your method for diagnostics, of course you can make a few full turns, but they're going to be slow.
Os BR são os caras mesmo. Nós diagnosticamos rolamento de roda com defeito girando com a mão e sentindo a vibração pela mola com a própria mão mesmo. 🇧🇷🔧
If you have no lift driving down the road turn the wheel back and forth if it growls turning left it is the right bearing if it growls turning right it is the left.
If you really wanna find a premature bad beating you can go as far as taking the wheel off and pulling the rotor inward and outwards from the side and from the top and bottom. If it’s got play you have a bad bearing. If there movement with the tire on then you got a really bad bearing
@@davekana8388 it's a stethoscope and instead of putting it on my ears I held it to the microphone on my cell phone. www.amazon.com/dp/B0015DLMOO/ref=cm_sw_r_cp_apa_i_NYEaFbN0QVMJG
Everyone is explaining examples of how to diagnose. I’m more impressed with the filming guys foot coming into frame to point where to put his stethoscope 🤣🤣
That's right. I've tried to show that to young guys, but they insist on using their "Dr. Mechanic" stethoscopes. Oh well, I've only been a tech for 39 years, what do I know?
Bought a used car, and im bringing back to the dealership after driving less than 200 miles.. hope they honor the 3000 mile power train warranty. The fact I hear this, lets me know they didnt test drive the csr themselves
By chance, what is that tool you had used to diagnose it? Just having the vehicle lifted and shaking the wheel back and forth will tell you everything you need to know. Good work🤝
Some believe only a real mechanic, can do just a test drive. Real Mechanic will look more into, than a test drive, a real worn wheel bearing, test drive may be ok. But a real mechanic look for other signs to. EXAMPLE: grease around inside of tire, had to come from where? Wheel bearing. Jack up car, grab tire try and wiggle it. Another sign. Run it on lift, long skrew driver, metal to metal, listen ear to handle. Compare both sides. You’ll hear it. Even a NEW BEARING MAY BE BAD, don’t mistake a rebuild job from China as ,”CRAFTSMANSHIP!!!”
Check all 4 wheels. Nowadays, the others arent far from similar. When theyre that bad though, the really bad one is easy to find. If its tough to nail down, elusive it seems, the other axle is where you may find its coming from. Even tire wear can fool you and be the cause on some types of noise people suspect bearings for. The fix is where you find it. Said the ol sea captain
It really depends on the car. Some don't make noise but are very apparently worn. You really need to confirm these things when working on a customer's car.
@@TheGamersRace Too true. I once owned a 69 Cutlass and the wheel bearing went bad in a *big* way. I was "flying" down the highway when, out of the blue, the front right wheel bearing got so hot the retaining washer "melted" over the wheel nut. I thought I was having a flat, stepped on the brakes (drums all around), and the brake shoes pushed on the drum and the whole damn wheel shot off an bounced into the air then off into a ditch. The front end dropped onto the ground and tossed sparks up into the air. Was a shocker.
That doesn’t really make sense, unless you are making money off selling parts! I changed a wheel bearing on the front passenger side of my car 200,000kms before the drivers side needed changed!

Put your hand on the spring. Just spin the tire. The spring amplifies the feel of the bad bearing

Do circles in a parking lot
Go left, go right, faster wheel is on the outside of the turn
The stethoscope is the most precise way I've found.

Use a long screwdriver, put the tip on where you want to hear, put your ear on the handle. Works like the stethascope you are using.
Driving 5 minutes down the highway and zapping each side with a laser temperature gun is foolproof and less work.

Dang i coulda used that method earlier to check my new (technically old) ranger i got the other day. One was bad so i ended up changing all of them anyways. Ig i got new bearings out of it lol
Never heard of this one.....please Tell me more.
Noah, you get the wheels off the ground ,spin the wheels one at a time while grabbing onto the coil spring. If the bearing is bad, you’ll feel it in the spring
@@noaht5191 its easy grab the coil and spin the wheel if you feel any vibration, the wheelbearing is faulty and need to be replaced. The vibration fealt from a faulty bearing is very noticible
I want this tool great preventative maintenance
This guy really went full doctor on probably the most easy vehicle diagnosis. You can be deaf and still figure it out
Not necessarily. My rear wheel bearing is going out and it only makes noise i can hear over 35mph. So doing a shake down by hand doesnt show the side thats grinding. This actually helps a lot.
👍👍👍😂😂😂
I thought your suppose to rock the wheel for any play on it
@@whatliesbeneathurbanexplor1631 thats only on extreme cases when the bearing is completely fucked
@@fungustmaster The ex had a wobble.
Good jobs sir
Hey thanks thats exactly what my car sounds like. 👍
I'm.. to
My wheel bearing is making a creaking popping noise. At the beginning of this video, I can hear the same noise, except mine is louder. Probably because of the weight of the truck on it. Similar to a CV joint clicking. I bought the new hub assembly, and as soon as the rain stops here, I will be installing it. Thought I'd share my symptoms in case someone else is experiencing the same problem. 👍
Update, the wheel bearing hub assembly solved the problem. It was pretty dried up of grease inside the bearings. Will need to get one for the other side soon probably. I thought I was going to need a torx bit socket to remove the caliper bolts 🔩 but it had standard hex bolts like 13 or 15 mm. For some reason, they have a different part number for the driver's side and passenger side. You need the hub with the slotted disc for anti-lock brakes (all-wheel ABS) if your truck has 4 wheel ABS.
You don't need that tool to find a bad wheel bearing, and the second thing is it doesn't matter which wheel bearings bad you should replace both of them.
The issue is with the customer. Around here bearing replacements can cost $1000+ per side. If the customer refuses to do both then they can just find a shop that'll do the single side. That's why most shops will only do 1
@@DaDaDo661 you can replace wheel bearings for 100$ yourself why tf r u spending 1k per side

Stethoscope for cars ❤️👌💪 love the idea 💡 I am a paramedic and really I am amazed
Bad or failing wheel bearings also make a clunking noises when you brake
When the do that you feeling vibration on the spring when you hold it and spin the tyre? Because I have that symptoms and I don't feel any vibration at the same time on the spring!
Thank you
I have a steth a scope in my kit to this day for noisy bearing identification good to see others still use it
great for pulleys too! love them
Yea a good yank on the wheel is all you need to do
Car on axle stands. Use piece of timber against one tyre to stop rotation so diff powers other one. Repeat for each side and noisy one will be obvious.
Looks like a subaru. I've swapped all 4 of mine out already.
Much simpler way, lift your car and try to push wheel in and out, if its moving it mean your bearing is bad.
Also check your suspension for movement, for sure just spin wheel by hand.
Interesting technique; I typically use a stethoscope 🩺
Thanks fam for everything
No need for a test drive when you do this. Pretty obvious. Best test.
I've done this many times over the years when I used to work on cars. Trying to figure out what wheel bearing to be 100% sure of can be hard otherwise. You want to make sure you did the right one. If you do the wrong one and it's not fixed, not you have to eat that job and do the right one. Now you're losing money. You're also making sure it's ot the CV Axel. Generally th eouter one will make a poppng noise when turning, but the inner one can be harder to figure out if that is the noise. If the brearing is not maing any noise, is could be the axel. If the boot is ripped and it's been throwing grease out of it for a while, that would be a big clue.
Sounds can really trick you when driving a car trying tohear the noise and you think it's coming from the Right Front and it's the Right Rear. The customer is telling you it is making a noise from someplace but it's someplace else. If it's making any noise at all. The number of times I went out on a test drive and let the customer drive because I couldn't hear what they were talking about, and yet it makes no noise when I'm sitting there and they're driving,.... You can start just ramdomly looking around the car trying to find something.
But using a Stethoscope on a car is something I did all the time;. I figure this is a normal thing most all Mechanics do. I still do it, but I'ma Mantenance manager for a food factory and so will use one on one of the Insutrial machines to an exhaust vent to head if it's making any noise. If that is the issue or not. Noise does travel and so you check both sides, and make sure you have the right one. There are rare times that both sides are bad, but one is worse than the other.
a good idea would be to replace left & right wheel bearings.
Watching the wheel bounce from being bent explains a lot as well as why the next wheel bearing will fail
Doubt its a bent rim. Alloy rims get cracked, not bent.
@@notonyt7339 I can tell you I've had loads of bent rims that weren't cracked-look at the rim bouncing-its out of round therefore bent-this will cause tremendous wear on a bearing-try taping a weight on a single fan blade and turning it on high and see how long it lasts
@@mungaloyd1 Every time I've had issues with alloy, its cracked.
Just looked into it though, and you're absolutely right. They do bend.
I always thought alloy only cracked, but ya learn something new everyday :)
Much easier to grab the coil spring and spin tire by hand.... you can feel it .
I know right lol
Unless it's an AWD car, in which case good luck spinning the wheels so freely by hand.
@@zoravar.k7904
You still can soon by hand..... it's easy for me.... i'm 6'5 and 400lbs. Not much slows me down
@@scottbaldwin4654 you can turn them, but you will not feel much vibration in the coils since they're not going to be turning fast, as you're trying to back drive the AWD system which will decelerate it, it might be easier on some cars, but on my Subaru it wouldn't be possible to use your method for diagnostics, of course you can make a few full turns, but they're going to be slow.
Just a tip, if you have ABS just remove the sensor and lube your bearing and see how long it will last.
Os BR são os caras mesmo. Nós diagnosticamos rolamento de roda com defeito girando com a mão e sentindo a vibração pela mola com a própria mão mesmo. 🇧🇷🔧
Só pela roda torta tenho certeza que o próx rolamento não dura a garantia kkk
If you have no lift driving down the road turn the wheel back and forth if it growls turning left it is the right bearing if it growls turning right it is the left.
Did u know if u grab the spring while it's spinning u can feel the roughness of the bearing also?
this and you won't even need to spin the wheel too fas
If you really wanna find a premature bad beating you can go as far as taking the wheel off and pulling the rotor inward and outwards from the side and from the top and bottom. If it’s got play you have a bad bearing. If there movement with the tire on then you got a really bad bearing
How to identify which wheel bearing is bad
What device are you using to amplify the sound?
@@davekana8388 it's a stethoscope and instead of putting it on my ears I held it to the microphone on my cell phone. www.amazon.com/dp/B0015DLMOO/ref=cm_sw_r_cp_apa_i_NYEaFbN0QVMJG
Nextgen Car Care, LLC smart idea! Thanks for the link, I drive older cars so the would be a good thing for the tool chest!👍
What will happen if you don't change them?
What's the diagnosis Doc ?
Everyone is explaining examples of how to diagnose. I’m more impressed with the filming guys foot coming into frame to point where to put his stethoscope 🤣🤣
Or just hold the coil spring and you can feel the vibration from the bad wheel bearing
That's right. I've tried to show that to young guys, but they insist on using their "Dr. Mechanic" stethoscopes. Oh well, I've only been a tech for 39 years, what do I know?
I didn't know either one of these methods. Of I heard the bearing going out id just replace both sides mos tof the time
My dad used that little tool to diagnose a bad alternator once, nifty things.
Depending also the mileage, it is a 2008 Hyundai Tucson
probably looks like one
Bought a used car, and im bringing back to the dealership after driving less than 200 miles.. hope they honor the 3000 mile power train warranty. The fact I hear this, lets me know they didnt test drive the csr themselves
This is a smart way of working.
By chance, what is that tool you had used to diagnose it? Just having the vehicle lifted and shaking the wheel back and forth will tell you everything you need to know. Good work🤝
Some believe only a real mechanic, can do just a test drive.
Real Mechanic will look more into, than a test drive, a real worn wheel bearing, test drive may be ok. But a real mechanic look for other signs to.
EXAMPLE: grease around inside of tire, had to come from where?
Wheel bearing.
Jack up car, grab tire try and wiggle it.
Another sign.
Run it on lift, long skrew driver, metal to metal, listen ear to handle. Compare both sides. You’ll hear it.
Even a NEW BEARING MAY BE BAD, don’t mistake a rebuild job from China as ,”CRAFTSMANSHIP!!!”
Well you would still change both as it’s the same axle and you have to match what you do per axle
Yeah, it't good idea to change both bearings
Kind of of hard to feel the Grinding from the spring via video/audio but you can definitely hear it via video/audio.
For the people that don’t have the luxury of the fancy lasers or a field by hand this is more efficient and a lot cheaper
Oh man ! The things you've learn from TH-cam
th-cam.com/channels/H3lwnPnTGySk4TPJA3LyvA.html
Check all 4 wheels.
Nowadays, the others arent far from similar.
When theyre that bad though, the really bad one is easy to find.
If its tough to nail down, elusive it seems, the other axle is where you may find its coming from.
Even tire wear can fool you and be the cause on some types of noise people suspect bearings for.
The fix is where you find it.
Said the ol sea captain
Umm just grab the strut & spin the wheel you'll feel it in the strut🤦♂️
Okay smarty pants
There’s more ways to diagnose you know.
Usually I just shake the wheel when I have wheels off ground or listen for humming when I'm driving but hey if that works for y'all then hell yes
I never really used this for bearings but I'm sure in the beginning of my career I have used some tools older mechanics and tech laughed at me for. 🤣
Pry bar held up to your ear works just as good I've you've always got one of those handy.
Cool, what tool are you using ?
You can often hear or feel it in the coil spring, too.
If you have a good 2½ long flat head , and hold the handle to your ear does the same thing. Also use it to hear lifter knocks.
Lmfao I can just hear when a wheel bearing is bad and I'm not being cocky just several several years of experience.👍
That’s epic
It really depends on the car. Some don't make noise but are very apparently worn. You really need to confirm these things when working on a customer's car.
@@TheGamersRace Too true. I once owned a 69 Cutlass and the wheel bearing went bad in a *big* way. I was "flying" down the highway when, out of the blue, the front right wheel bearing got so hot the retaining washer "melted" over the wheel nut. I thought I was having a flat, stepped on the brakes (drums all around), and the brake shoes pushed on the drum and the whole damn wheel shot off an bounced into the air then off into a ditch. The front end dropped onto the ground and tossed sparks up into the air. Was a shocker.
@@stldesperado8184 I bet that was the last time that happened
So is that 14 years 49 years experience
Good idea
th-cam.com/channels/H3lwnPnTGySk4TPJA3LyvA.html
I always change them couple .Front two or rear two.
That doesn’t really make sense, unless you are making money off selling parts! I changed a wheel bearing on the front passenger side of my car 200,000kms before the drivers side needed changed!
Hard part of having a all wheel drive is you have to Jack entire car up
