I've searched on the forums and google and cannot find an answer. I had some rear end clunking going over bumps at low speeds, and put my car on jack stands to diagnose. I think I found the culprit: the passenger side mount for the differential. I looked in the 04 coupe FSM in RFD-10 and the picture lists an "upper" and "lower stopper" (#5 and #8 in the picture). The upper stopper looks like its almost gone, and there is a large space where metal mount sandwiched between those stoppers is hitting the metal frame of the car over it.

Now to my questions: where the heck can I get these stoppers? I tried looking through infinitipartsusa and googling it, but did not come up with anything. Has anyone had experience replacing these? It looks simple enough, just jack up the car, remove the bolt, slide the old stoppers out and the new stoppers in.

I can stand the noise, its just a minor annoyance that happens maybe 1 time every day. I can live with it, but just don't know if it will cause any damage in the long run without replacement. Any help would be appreciated.

 

Energy Suspension now offers a rear diff kit that I think they offer separately. It also is included as a part of their 7.18108 Master Kit.

 

Can someone tell me which direction the upper stopper is supposed to be mounted. I am changing my rear differential and can't tell which side was facing up when I dropped the diff. I've been looking for diagrams of it and none show more detail than the one above.
