I think my t-case is slipping.When it is under load or i bounce it hard it shifts from 4lo to 4hi by itself. Here's my questions: Is that normal. ( I don't think so) If the case is slipping is it cheaper to buy a new one or rebuild the old. If rebuilding is cheaper, where can i find the best parts for the money?

btw,its the chaindrive t-case.

 

Check the linkage and particularly the bushing for the horseshoe where it crosses over to the other side.

 

I crawled underneath the truck last night and all I found was a rubber boot attached to the top of the horsehoe. Is the bushing gonna be like a suspension bushing or is it metal. I already fixed the one that was inside the cylinder shaped deal on the passenger side at the bottom of the horseshoe. If possible can i get some pics of where the bushing should be? Thanks.

 

You can try inverting the boot. The boot would then be much lower on the t case shifter. It then wouldn't be able to get the leverage needed to pull you out of 4LO.
