do you have any trouble staying in 4 low at all? is it kind of a clunking noise? I have the 2.5 RC lift as well with a tcase drop. I can shift into 4HI fine, but it won't stay in 4Lo b/c I need to adjust the tcase linkage. Most of the trails I am on right now, I don't need 4lo, so I haven't had a chance to adjust it yet.
