Recently did something quite similar, wheel bearing cost me 100 bux from a local parts store, and that was JUST THE BEARING. Ill also have to admit on my 91 teg, the rear engine mount was the WORST of the all to replace!...also keep in mind, i found that the front mount was just as bad, and in fact just decided to replace them all! Its not that hard to do the side 2 and front yourself...as for the wheel bearing, that's pressed in, id just remove the steering knuckle from the car and take it to a shop to have it pressed out. Do these 2 things and youll still spend around 200-300 bux...
