Don't overlook the possibility of a bent axle shaft or bent rim. If you bang
into a curb can easily bend these. Perhaps the best way to check is have someone
follow you and watch your rear tires. If they wobble, you have a either a bent
shaft or a bent rim. If one is wobbling, switch the rims from side to side. If
the wobble follows the rim, you have a bent rim. If it stays on the same wheel,
you have a bent shaft.
