This is a pic of my differential rear crossbar mount. (Don't know the proper terminology here) Common sense would tell me it should be sandwiched between those two washers/bushings. I guess this is where my faint clunk is coming from when switching gears. It was solid as a rock after I installed my RT style front mount, but it has slowly developed a slight clunk again. Would the nuts have backed off or something? Should I just run them back up, or are the bushings worn out and compressed? Both sides look the same....

looks time for new bushings to me

New bushings are in order for sure. Unless you like the rock hard ride of a lowrider.

I kind of figured so.

Any suggestions on an upgraded option? Would poly be a good choice for these?

I had poly and removed them. This all depends on the use of the Z . I found that poly transmitted gear and road noise into the cabin. I switched back to the OEM rubber and it eliminated about 40% of the combined noise. I didn't notice any difference in performance.

I already have a noticeable amount of gear noise, so you definitely just talked me out of poly. Where is a good source for the OEM bushings? All I've found on MSA are poly.
