I have changed my driverside axel but it still wabbles. What's the next step, should I change the gears or the whole differential?The driversidewheel was hit on a curb real hard.[/blockquote]

 

Did you replace the axle bearing? Did you replace the wheel and tire? The wheels bend before the axles, and tire cords and axle bearingscan get broken by impact. If you replaced the wheel, tire, axle shaft, and axle bearing,and the wheel still wobbles, you may have bent the axle housing, the differential is not going to make the wheel wobble.
