Default Clunk from rear diff after upgrading the diff mount

I installed the ASP (Street) Rear Diff Mount a few months back and I was surprised by what a difference it made on pretty much eliminating the clunk I would get between shifts, but lately I've been getting a really bad clunk coming from the rear diff when letting off the throttle. Is this common with aftermarket mounts? It almost seems as if I'm back to the stock mount only worse. I can eliminate the clunk by slowly letting off the gas.

Maybe engine or tranny mounts? Your sig doesn't list anything for them.

Default I had that too with the power ring thing. I have ASP street motor and trans mounts too...

I took the ring out because the clunk drove me nuts. I made sure that everything was installed correctly at least half a dozen times.

I may give it another shot or possibly the ASP or Apikol rear diff mount.

No, I'm still on the stock Trans and Engine mounts. Maybe those need replacement

Default I had that and vibration from the ASP mount. Just put in the Stern ring

and now I have no clunk, but vibration from 60-80 MPH. When you take the slack out of the diff mount, all that energy has to go somewhere. I'm trying to find out if it's my engine/tranny mounts or driveshaft. Good luck.

Default I have both. I didn't notice a lot from the bushings, but I don't think my OEM

bushings were worn. I just put the diff ring in over the weekend.
