I do own/drive a T4R, but this is an issue with my other car, which is not a 4runner. Its a GMC Acadia, and its complete garbage, but I know you all are smart folks and Ive received little/no help on an Acadia Forum.

Im having some pretty bad wheel shake at 70 mph (settles down above/below 70), and then an odd bouncing feeling around 30mph. The bouncing feels like it is coming from the rear, while wheel shake is felt a bit all over.

Im curious the symptoms of a bent rim vs. a balance or alignment issue. Or is it something else entirely? Ive taken the car twice to get balance and realigned, and its had zero help at these.
