there is a TSB related to the front bearing, but I've not heard of this occuring on the 2008 models
If the vehicle operator describes or the engine is making a tick, knock, rattle or tap noise,
verify the noise by checking the following:
1. Remove the accessory drive belt and listen for sound at 1,500 rpm.
2. Is sound still present?
a. Yes >>> This bulletin does not apply further diagnosis is required.
b. No >>> Proceed to repair procedure.
