Rear Wheel Bearings

[sclem]

I have a 2007 Tundra, I have had to put rear (left & right)wheel bearings on 2 (TWO) times. What is the problem?

huh? Why?

[Mr. Creosote]

On my Gen 1 it took four trips to the dealer to resolve a growling rear bearing issue. A touch of quality control from the factory, plus a heavier helping of mechanic incompetence at the dealer.

are you overloading the bed?

Could be why maybe?

Since I've never heard of ANYONE needing to replace the rear wheel bearings on a gen2 Tundra, I think the problem is, someone thinks he's being funny.

I load the snot out of my truck, have 36,000 miles on the clock, and the bearings are like new.

edit: I note from sclem's other posts he has 95,000 miles on the clock, and maybe hasn't kept it properly lubed. I believe the wheel bearings are lubed by the differential oil -- but maybe someone with more mechanical background will correct me on this -- so if sclem does a lot of highway miles (to reach 95 K in 1.5 years, I'd guess he probably does) there may have been inadequate slow speed and stop and go which I understand -- again could be corrected -- helps to lubricate the wheel bearings.

Anyone else heard of rear wheel bearing problems on this truck?

And to the OP -- have you changed your diff oil regularly?

Finally, again to sclem -- how much does it cost to replace the rear wheel bearings?

You are right the bearings are lubed from the differential, but it should not matter if he drives freeway or stop 'n' go, I tend to lean towards the differential fluid is not at the proper level and he is running "dry" bearings. Of course over-loading means all bets are off...:whoo:

I've replaced several of these bearings on my trucks (94 and 85 4Runners). They are sealed bearings that are prelubed, no grease packing needed. To properly take them off they must be prressed off. There are tricks that can be used to get them off by building a home made SST and slamming it on the ground. This is fine to remove the bearing since it's bad anyway, but the new one should be pressed in. Maybe they used the slam it ont he ground method to put the new bearings on also!
I don't think the bearing is lubed by the diff at all, not on my older trucks at least. There is a seal that the rear axle slides into inside the housing. The bearing would technically be on the other side of this seal closest to the axle stub. Your rear axle tube should have a bulge to it when it reaches the outermost portion, this bulge is where the bearing rides.

If I can find any pictures of the setup on my trucks I'll post up.

Toyota Maintenance: Replacing Rear Wheel Bearings and Seals

Here is the processs I'm talking about, this is for drum brakes however. Don't know how it works for the Tundra with disc, but think it would be essentially the same.

Well i had to have one of mine replaced under warranty, they told me it was my tires making all that noise since my 5K mile oil change then they finally got it right at 20k mile service. So, I am SOMEONE who has had a problem with my RWB in a 2008 tundra. But twice does seem excessive.

Cheers.

I have a 2005 Tundra. It was making loud humming noises and I pretty much deterimined it wasnt' the tires. I'm out of warranty with 65,000 miles. Toyota service said I had to have both rear axle bearings replaced. They quoted me $1120 for parts and service.

So, they got my money now. I just wanted it fixed since I'm planning on keeping this truck for a while. I pick it up this afternoon.

I have a 2008 Tundra I purchased new May of 2009. At 30,000 I was getting a slight growl, only noticible when I was coasting to a stop. I had my 30,000 mile check-up done. All the required maintainence. Had the front end presicion aligned, the wheels all balance. One even had the tire properly set to the rim. They checked the differential fluid. All up, but the rear had a sheen to it. Had new synthetic lube installed (manufacturers spec). That drone though was still there. Hardly noticable, but there. For the last few weeks it has gotten more pronounced. Another check. Left rear wheel bearing. At least I know I wasn't crazy. So now it's off to the dealer I had look at it at 27000 and was told it was a "normal" noise. NOT! My truck is usually just about empty. So there you have it.

I have to go with troll he hasen't been baqck .

Toyota recently issued a TSB for the rear bearings on our trucks... they will replace them, no charge.

i had my rear wheel bearings done too with about 28000 miles
