Rear Axle Question

[automated1]

So here is my deal, I purchased a 97 4runner SR5 V6 Auto last week. The rear wheel has a wobble and I have determined that it must be the axle flange that bolts to the wheel is out of shape from a hit? Anyway It currently has 16" alloy wheels, but inside the drivers door the vin plate says 15" wheels... So I am sure I have abs so is it safe to say that its the axle with 16" wheels and abs? The parts stores are saying there is 3 versions for the 4runner. 15" wheel, 16" wheel without abs, and 16" with abs. If anyone has any tips on replacing I would be greatful also. Best price I could find so far was with Rock Auto $193+shipping for new. Im not apposed to purchasing used if I can find it. I am from Pittsburgh Pa if anyone knows where one is around the area.

. Pull out the axle and have a machine shop check it out. It could also be a bent wheel.

I did switch wheels yesterday while I had the 4runner jacked up to rule out the wheels. One thing I havent checked for sure is to make sure there isnt anything holding the drum at an angle. I did pull the drum and I swear it looked fine and nothing was holding it so I guess I'll be pulling the axle. Tonight I plan on removing the rear wheel, removing the drum, putting the tranny in neutral and spinning the axle by hand and trying to watch for the movement.
