Car Forum / Driving, Maintenance, Tuning / Maintenance and Repair / April 2008strange noise from rear of fwd car
after a bumping a curb (sliding sideways), a fwd drive car makes a low- pitch wallowing sound at the rear. the tires were replaced and an alignment was performed. this resolved other issues, but the sound persists. the dealer did a precise alignment on top of the local shop's alignment. turning right makes the sound go off. also, the sound is not audible until 70mph or higher. any idea what this could be? a jacked up wheel bearing or rotor wouldn't go quiet if the car turned right. do fwd cars have little boxes that act like non-posi rear axles? if they do, my guess is, that is messed up.

A wheel bearing *WILL* get quieter if unloaded. nate  Signaturereplace "roosters" with "cox" to reply. http://members.cox.net/njnagel >after a bumping a curb (sliding sideways), a fwd drive car makes a low- >pitch wallowing sound at the rear. the tires were replaced and an [quoted text clipped - 5 lines] >turned right. do fwd cars have little boxes that act like non-posi >rear axles? if they do, my guess is, that is messed up. I would replace the wheel bearing first. When you turn the load changes on the bearing which can change the noise the bearing is making. Steve B. |
