Well I have tried to figure out this problem for a long time and i think its time to ask the experts. Okay so when I go to brake or give it gas or anything that creates force on the body it feels like something is shifting back and forth. What torque do the engine mounts have to be at? I have them snug. What other mounts/bolts could it be? Any pictures to help would be appreciated. Thanks

 

Take a look at the transfer case.

 

everything seems tight in the tcase and trans

 

Bushings? Look where the rear shocks meet the body. Play in the U-joints? Thats a tough one. I know this sounds funny, but have you checked your spare tire?

 

HAHA my spare is bolted to my roof rack, its not going anywhere. It feels like the engine is loose but i know its not i'll check the u joints. Shackles maybe?? I'll check the rear shock mounts but i'm getting a set of BPE's soon.
