bump ~ still got the problem ~

 

somethings not weight balanced it seems. Check the tire balancing or you might have a tire buldge.

 

tires r ok
the prob. was (i am guessing since it has not do it agian since i did this) my rotor on the rear passenger side had grooves in it cause the rear break pads were shot i resurfaced the rear rotors and its been a week now and no thump yet
