Once I put everything back together, I found that both rear wheels wobble back and forth, one worse than the other. I thought my axles might be bent so I replaced them with new axles but the wobble it still there. I also had the rear wheels checked and they aren't bent. The carrier bearings and axle bearings are also new. At this point I am thinking that maybe something is wrong in the posi? It doesn't make any unusual noises. Any ideas?

Could be the pinion backlash causing a pinion vibration?
