A few weeks ago I sideswiped a concrete wall going about 80 on the interstate. I got two new wheels for the front and back but now when I drive i can see my back wheel wobbling. I cant feel it but i can see it. Anyone know what can be wrong and how much i'm looking at to fix this. thanks

Probably either bent the axle or the housing. Most likely the axle shaft. Axle shafts aren't too tough to put in. Let me know if you want instructions. Otherwards a shop would probably figure it out for under 2 hours labor(I would hope)

I would bet on the hub being bent.. samething happen to a jeep I had.

The hub is one with the axle on GM 10 bolts.
