I recently bought some xd hoss 20's on 33's for my 08 lmm, the first day the truck seemed to ride fine, the next day i brought the truck in for an alignment got it back and around 45+mph i feel a slight vibration in the seat and also in the steering it is felt. The alignment shop also broke one of the upper control arm adjusters which was replaced by stock parts. But the steering wheel itself isnt visible shaking but when you put a grip on it it is felt through the wheel. I just installed the wheels the day before the alignment and they were just mounted and balanced. The only thing i could think of is try to check the balance. Or is there anything that the alignment could do to cause this?

Check the weights on the wheels, verify that none of them have ejected themselves.

They all seem to be in place, i guess i will start with a rebalance and go from there.
