Whenever I make in a turn, theres a clunking noise back by the drivers rear wheel. The wheel is on tight and everything, so it's not the rim wobbling. And it only happens when I turn.
Any thoughts?

Ball joints, drag links, or axles maybe. Is it one clunk or continue with rotation ?

It's like, once the wheel makes a complete rotation, it will clunk once. so its like clunk-pause-clunk-pause-etc.

I would jack that wheel up and grab the tire at 3 and 9, then at 12 and 6 and try to wiggle it and see if there it any play in it, if there is look at suspension parts while wiggling and see if you can tell where it is. Migt try to rotate the tire back and fourth while in gear to see if the axle shaft has excessive play.

Year?

A Arm Bushings.............Pre 88?

I have an 88 Coupe - turning right - I get a rear clunk - Left trailing arm bushings are shot - the end that bolts to the cradle is completely gone - metal on metal.
