So how in the &^%$ did this happen??? I had been experiencing some odd shaking on accelration and especially on braking. At first I thought I had warped rotors but my mechanic finally diagnosed it as a bent rear whell hub. They fixed it and sure enough the problem is gone. I do some off-roading but nothing *********, and don't recall ever banging into anything hard enough to bend a wheel hub. Just another uneccesary problem that cost too much to fix.
