I Pulled the rear wheels off, along with the shocks because I noticed strange movement when I did this once before. With the wheels off, I can grab the rear caliper and move the wheel up and down two inches easily on the right side. When I repeat the same activity on the left side, the whole thing goes up and down three quarters of an inch. I put a little more effort on the left side than the right side. I called a couple of useless repair shops on this side of the town and one guy said basically, "If it ain''t broke it, don't fix it"...which may or not be a Southern justification for a number of things. Any suggestions??
