2007 3 door 350000 miles eats wheel bearings!

[webfeet69]

hears all the info i know,
The car is my father in laws owned since new. the car is used for package delivery hence the milage. by the way the car doesnt use any oil and he hasnt had any problems until this big problem. He started hearing a growl and found the rt front bearing was bad. replaced the bearing and he still had some noise. they then found the trans main bearings were worn and put in a used trans. all was well for 300 miles! same bearing went bad again! he has since put 5 wheel bearings in the car. he has tried just the bearing itself, new bearing from toyota, totaly new hub assembly from toyota. He just called from lee mass and said bearing is making noise again. 280 miles this time! Any ideas? the only thing i can think of to check when i get the car this weekend is all trans and motor mounts. i am thinking that if the mounts are shot then its possible the engine moved putting side tension on the bearing causing the failures. the car has never been wrecked or damaged.
Thanks in advance,Todd

Wait.. he doesn't use OIL?

those mechanics are idiots.

find a new place to service the vehicle

thanks for your input and stating the obvious but i need a master tech's input please!
Thanx:help:

Since wheel bearings are pretty reliable, repeated failures are likely due to some factor outside the bearings themselves - a bent spindle? - maybe faulty installation - over-tightening the spindle nut, leaving out a spacer, something like that.

I would start looking for a replacement. You obviously got a bad Yaris!

[Kal-El]

Wait! There's anther 350,000+ mile '07 Yaris in existence?? :eek:

To the OP, there's a member here with a sedan over that mileage. He was thought to be the only human to drive that much. :tongue:

If you could get up any pics (odometer pics too) and more info about the car it would be great!

:thumbsup:

i have a getting loader whine on very smoth roads have not looked into it much but it does run with the speed of the car . im hoping it not the wheel bearing but till it really gets worse hard to tell exactly what it is and i have 58000 miles and im sure toyoya would call that a wear item so they will not take of it i bet anybody that has any thing that sounds like this problem please give me a heads up i know cars pretty well i could put the car up on jack stands and run it and see what i get kinda sketchy but i need to find this noise its driving me crazy

[trini_per4mance]

Wait! There's another Yaris out there with as much miles as mine? WOW! This is great news for Yaris owners out there. Just goes to show the reliability of this little car. Bottoms Up!!!

[YarisSedan]

Probally the mechanic who pressed the bearing installed it incorrectly? The bearings on the yaris are pretty bullet proof. Unless he hit something really really hard to damage it.

sorry for coming off topic but, the amount of miles you have on your yaris (and continue to add to) never ceases to amaze me :thumbsup:

[Dans08]

I've seen on Hondas where the knuckle is out of round and that distorts the bering when it is pressed in. Dan

[yaris-me]

I'm no expert, but try looking into the wheel or tire. It may be out of round or bent to one side and is causing too much stress and bearing failure.

[jambo101]

Do they still manually pack the bearing with grease before installation if so they may be forgetting the procedure or using the wrong grease ,If its just the one bearing it might be prudent to bring it to the dealer to have it done according to factory specs.

I almost made this same post earlier today. The only thing that stopped me is how quickly the bearings are getting killed.

Good luck with it!

Bad batch of bearings? Do they put lot numbers on replacement wheel bearings?

Any news op?

[toast]

Try a different brand just for kicks. I'm betting something else previously mentioned is bent, out of round slightly etc. A different brand of bearing may have an ever so slightly different tolerance or materials etc and *might* have a different result. My old truck was going through the expensive brand bearings every 10k after it hit 90k. After a couple of sets of those I switched to the extra cheapies at AZone and damned if they didn't last for 30k. That truck was beat all to hell fyi.

Wow thats a lot of miles!

Only thing I can think of is whatever is between the hub assembly and trans which is the drive axle. You already changed out the hub with a new toyota one which is the first thing I would of recommended to check.

Motor mounts should be okay since the car is always moving forward because of the amount of miles on the car, 350K, which means it probably rarely sees any stop and go traffic to wear out the mounts.

The only thing I can think of is the drive axle. Either its worn/unbalanced/distorted in way that causes a harmonic vibration at a certain speed to kill the wheel bearings that quick. From the high miles from delivery, it looks like its run at a certain speed continuously to obtain optimal fuel mileage and whatever that speed is, is where the harmonic vibration is worse causing the wheel bearings to fail. Also check for tire or wheel runout, or "out-of-round", maybe a combo of the two is causing the accelerated wheel bearing failure.

I dont know the exact cause, just throwing some theories out there but I hope this helps you in your journey on getting the problem fixed!

I would have toyota look at it so if its fails after they fix it, they will stand behind you. 350,000 miles Im sure something else is going on but congrats I have 117,000 on my '07, going strong having only changed trans fluid, oil and filters and coolant, new set of tires, and new serpentine belt.

[birdman]

350 thousand miles is amazing. With that kind of mileage its natural to have things wearing out. What amazing cars these Yari are.

Wow, you do some driving yourself. Long commute or something else?

ok sorry about the long wait but problem solved!!!! After i got the car to look at and giving it a good once over i noticed the trans and motor mounts had worn allowing the motor/trans to drop and shift to passengers side causing all of the stress which caused the constant bearing failures and transmission failure do to side load!! i hope this helps if anyone else has this problem!
Oh yeah i have had requests for pics of car and odometer and will as soon as i have a chance.
P.S. the new trans mount is a much beefier unit from toyota! design flaw addressed???!!!
