1988 GTA rear end clunk
Just recently noticed that my 88GTA has a clunk from the rear and when going over speed bumps or very large dips in road. Doesn’t seem to make the noise going over potholes, smaller/uneven dips in road, etc.
Previous owner installed tubular panhard bar and trailing arms. I checked all the bolts for those, and they seem tight. Not sure where else to look. Previous owner also removed rear sway bar for some reason.
usually only makes the noise when straight on hitting a speed bump at 20mph or so.

Looks like it has nice shocks and rear disc upgrade. (Needs the ebrake cables)

For the floor pan being punched out around it and it just kinda flopping around up there.
Pop the back seats out to get at it.

Re: 1988 GTA rear end clunk
Ive had it on the 4 post hoist at work multiple times, I thought the exhaust was hitting in a couple places so I moved it. I’m gonna look again to make sure I’m not missing anything. Otherwise I think I’ll just ignore it.

Re: 1988 GTA rear end clunk
I see your sub-frame connectors are bolted in. Check those bolts while you are at it. I have heard that over time the hole drilled thru the frame can "whooler" and cause the connecter to move under pressure or when pressure is taken off.
