My 2011 Tundra has developed a noise that sounds like it's coming from a rear wheel. It sounded to me somewhat like brake noise and I had it checked out and the mechanic who test drove it couldn't hear the noise and said the brakes were like "brand new". I had them rotate the tires as long as it was on the hoist. The noise is still there and sounds like it might be coming from from the right rear. It seems to be when I am making a right turn. I crawled under the truck but didn't see anything obvious. Any thoughts?

If it's just on corners, you might have a problem with a spider gear in the diff.

Or a wheel bearing going south..

My first thought too.

Were the center caps off by chance when the mechanic drove it?

WinM,
I wasn't with him when he drove it but I think he drove it out of the lot before taking it into the shop so I don't think they were off.

I had a clicking noise on a 2006 that was caused by the plastic clips on the center caps being broken. An easy thing to check and rule out.

Posi?

My right rear wheel bearing went out at 80,000 miles. It squeaked for a long time before I took it in.

Automatic limited slip differential. This isn't really a squeak or a grinding noise...more of a rubbing sound

Turns out it was the inside lip of the rear rotors contacting the backing plate. Apparently not an uncommon problem. Toyota's fix is to replace bearings at $1100. The dealership ground down the lip on a lathe for $112.

Thanks for the update.

Why not just grab and pull the backing plate? At worst you use a pry bar or screwdriver?

$112.00 to fix something that shouldn't have happened?

Toyota has a Technical Service Bulletin out on this problem. While the problem is not covered beyond the basic vehicle warranty, since this is a known issue with these trucks owners have used the TSB to get Toyota to pick up at least a portion of this repair.

Why wouldn't it be covered by the warranty...unless of course its so common that they'd lose money fixing them all.
