Cannot keep motor and trans mounts together in my 96 Blazer crawler/trail rig. Stock engine and trans, no bent frame, have been through two sets of polyurethane mounts and that is with a steel cable running from the AC delete kit bolt to the frame and I also have a chain running from the bell housing to the frame. Now I'm breaking transfer case to trans adapters. It's a gremlin I cannot figure out. Any ideas where I should look to solve my problem that I'm not thinking about would be greatly appreciated.

Stiffen the chassis man a roll bar and some square tubing to ridged up the frame and body should help a lot sounds like it’s twisting and flexing the body and frame to much in my opinion

 

I broke poly motor mounts in my S10. I went back stock but wish I had used the JTR 2.8 mounts. Not sure if they would fit a blazer setup. Still rubber but a better setup.

 

I've been running energy suspension motor mounts in mine for a few years, and have yet to break one.

Maybe you need to fabricate some that use a bushed sleeve setup (kind of like a leaf spring hanger).
