hi! I recently changed out the shocks on my car and everything has been going good, until i heard clunking. I checked where the axle is attached to the hub and the bolts were coming loose so I tightened them all up. I then drove around but its still clunking, noticeably. its clunking in the left rear only, and it only clunks when I let my foot off the gas. Any ideas why this is happening? are the problems related, or am I missing something? all help is appreciated!

It could be the u-joints. Also, look for more loose/missing bolts.

A question for you. Does the noise occur when you do gear changes? I ask as I had the same clunk noise coming from the rear end of my Z when I first bought her. How bad are the mustache bar bushings? How is the mount that supports the diffy?

P.S

Dam Steve J beat me too this. Bolts, all of them. Check and recheck. Any bolt you removed or messed with take a look at it.

I beat you only because I was brief for a change.

Check the top of the strut. The nut up there clunks when it isn't properly torqued.

thanks for all the suggestions! it only happens when im off the gas though, would that really be because of bolts? and for pormorza, at the moment the cars automatic, but even still, its only when I let off of the gas pedal does it clunk.

Yep, the old clunk. I'm sure mine is backlash in the diff. Its done it since I bought the 240 and I tightened and checked everything. Its no worse or better so I view it as a feature of this great little car.:classic: My mechanic comments on the backlash every time he checks it for a WOF. (warrant of fitness)

would it just randomly start clunking though? it didn't do that when I bought it..

It might appear to be coming from the left rear but don't count on it. Sounds can travel.

Is there any play in the UJ where the spline goes into the diff?. I had that problem with an old '63 Holden.

If you've double checked the torque on all bolts and still get the "Clunk" when you take your foot off the pedal, I'd be inclined to check for play in the drive shaft UJ's.

My 72 clunks everytime i rapidly press clutch and change gear. Even yours is automatic, it still might be the differential cluncking. It's quite common or so i've read.

Worn differential mount and or differential strap? Worn Moustache bar bushings?

ok, ill be sure to check all of these asap! hopefully i can get access to a jack sometime today. thanks for the help! how would I check the u-joints? would just seeing if it moves with a little shake suffice? and hopefully as cash is saved i'll replace all the bushings in my car!

Have you tried looking at the FSM? I'm pretty sure it has troubleshooting guides.
