that's what insurance is for, make sure they check that your axle is not bent and that the gears are not damaged. if the rear axle took the hit, your drive shaft may also be out of balance, your wheel may be bent, the tire casing may have separated on the inside or your frame may also be bent. how are the alignment gaps for your doors including the rear gate. I would also have them pull the axle shaft and make sure that it's not damaged
