I kept hearing a noise emitting from the rear of my 86 T/A. When I push on it at the rear quarter side to side I can hear the thunk or "play".

Is this emitting from inside the rear end via the axles or is this something I can adjust from the wheel hub area.

Too much slack somewhere.

Thanks.......

might possibly be the panhard rod. bushing in it

strut,shock,or sway bar bushings are the likely suspects

Probably just the axles slipping back and forth in the carrier splines. There is a little bit of movement allowed in them. Nothing to worry about, unless you suddenly get about 3 feet of play

petes right, mine does the same just the little play in the axles

Another possibility that happened to be the answer for me was:
My spare tire had gotten loose and it, along with the crap jack + handle would shift under various conditions.

Thanks for the ideas guys. I DID have that 3 feet of play in an El Camino of 1979 Vintage. Looking in my rearview and saw my tire riding about 3 feet outside of the fender well.

Regarding the T/A it just started bugging me pulling into a driveway is the most noticable.

I was hearing a little popping or klank when I would go over certain bumps. It was the panhard bar... I hadn't got it all tightened when I did the exhaust. There is also the slack in the rear, but I don't think that should make that noise unless you had a huge problem. I'd say that you should start by checking the spare tire and the exhaust. Then move on to the suspension.. could also be the wheels. Maybe loose??
