Hi Scott, The first thing to do is pull that rear wheel. Jack the rear end up on jack stands and check the wheel for loosness, (grap it by both sides and see if you can shake it side to side and top to bottom). Put the car in neutral and slowly turn the suspect wheel by hand, any noises? Any lumps in the tire? Next remove the wheel, (any loose lug nuts?), now look at the constant velocity joint rubber boots on the rear axle, any torn or ripped? Check the eight bolts attaching the axle CV to the rear wheel, these can come loose. Check the shock absorber for worn rubber bushings. Also check your trailing arm bolts, make sure they are tight.
