I've got a '08 Toyota Sienna with ~56k miles. It is a certified pre-owned purchased back in April with ~49k miles. As part of the certification process, new tires and front brakes were installed.
Lately, I've been noticing a lot more 'road' noise. It is ONLY speed dependent; i.e. it does not change with engine speed, gear selection, brake pressure, etc. The only thing, other than speed, that does change the noise is steering. While driving, if I steer right, noise goes away -- as soon as I straighten out, noise comes right back. The noise is quite noticeable at speeds as low as 25 MPH. Last night, took a good look and feel of both front tires -- both are okay on air pressure and neither show any sign of abnormal wear.
Given all that, I suspect a bad bearing, and came across
this which would imply it is the right wheel bearing.
Basically, I am looking for any other thoughts on what it might be. Obviously, since it is only speed dependent, that tends to limit possible causes. Though the car is under warranty, and suspect any fix should be under warranty, I prefer to go into any servicing situation with knowledge and some level of expectation of possible problem(s). It certainly can't hurt to help point the technician in the right direction.
TIA.
