This is probably a dumb question but that has never stopped me in the past. I had my Bullitt up on jacks so both rear wheels were off the ground. I have had a slight sound while driving, thought it may be a rear caliper holding up so I was spinning the rear wheels to test. No hold up, just very slight drag which I think is normal. Anyway, I pulled and pushed the wheels in and out and they moved a little, maybe 1/16", maybe not that much but enough to hear them click in and out. Is this play normal? It's been a long time since I've owned a rear wheel drive car with an Axel and I don't know if a small amount of in/out movement is OK.
