With a stock samurai the t-case mounts are weak. I had 32's with 6.4 to 1 case and stock axles and gears and needed to rework the entire t-case cradle. Needs to be ridgid! They make bolt on kits to fix this and as long as you buy the good kits it will work. Mighty kong is the name of the kit I think. Look at how it is made and build it like I did.
