I hit a curb at about 10mph the other day but it was hard enough to know that I did it. The impact was on the pass. rear tire. Now, only when braking, I have a vibration coming from the pass rear tire where I hit. I would assume that taking a hard curb would most likely damage the axle if anything, but now the car drives fine EXCEPT when braking.
Could hitting a curb somehow warp a rotor???? or could a bent axle only cause vibes when braking??? Any input would be appreciated. Obviously I need to put some money into the car to fix this, Im just trying to figure out where to start.

 

axle bearings maybe.....but chances are good too you did get the axle as well.

Warped rotor would be felt in the brake pedal...these are my first thoughts that come to mind.

 

A bent axle might simply squirm on the rubber when rollng
but the run-out will make variation in braking force as the
caliper has to slide to track it (and unmaintained calipers
can get pretty sticky on the pins).

Jack it up, put some kind of indicator to the outer but
un-curbed area of the rim (even a piece of wood balanced
on a cinder block) and see what kind of wobble you find.

 

hmm, good idea. I was trying to think of a way to measure the runout without having to purchase a dial indicator. I will give that a shot.
