Rear control arm R&R requires dropping that side of the subframe to get the outer bolt out.

Jack the wheel free of the ground and apply torque via a lug bolt with the parking brake set. If the wheel moves back and forth, bushings are shot. If not, check to see if the sway bar links are still present, if not, replace.
