When does it occur? Single or repetitive noise?

Thinking exhaust or gas tank..

single klunk seems like when cold. exhaust tight also tank tight. reading other forums might check shock top bushing and disconnect sway bar link. to see if noise stops

 

I had a single clunk and it was the top mount on the passenger side shock. The inner rubber portion had torn free from the outer metal piece.

Couldn't tell until it was removed and inspected.

Lots of suspension clunking noises are hard to find when the parts are bolted together and under tension. Jacking up the car to get the weight off the wheels sometimes isn't enough to reveal the problem either. I've had bushings and end links feel rock solid until I unbolted them, then they were loose as a goose...

 

Are your rear wheels sagging inward? Gen 2 tend to have bushing sagg due to "spirited driving" or just how it was designed. It was more noticable.

When you have excess negative camber(excess can be just outside of tolerance) the end links aren't tensioned as much. The ride height is a tad lower. Left to right distance is shorter. They tend to clunk alot, even when the usual suspected parts were replaced.

The clunk is due to the range of motion not being equalized from the other side. It oscillate between high and low limit...

This can due to various things, control arm bushing, radius arm bushing.. All them bushing that's old and saggy...

Or poor suspension setup.
