My wife drives an 08 xb, 5 speed...always smooth as can be...then the other day we drove her xb to Tennessee (about 400 miles) and stayed up top the mountain..after a few days i notices a slight vibration slowing down, and figured we warped a rotor comin down the mountain, but then when we left and are driving highway speeds, about 52-70, there is a vibration, even almost like a grinding feel...Could it still be a rotor?? or somethin else?? any help would be great!!

 

Sounds like what I had 2 months ago wheel bearing is busted. Expect to pay $300+ for one.

 

well luckily her xb is still under warranty and so we took it to the Toyota dealership....ended up being a seizing brake caliper on the driver side....oh well...fixed now!!
