grinds worse in 4lo - used to be just in 4lo that it would grind but now its getting worse in tod mode than it ever has been - shifts fine and fluids have been drained and replaced in both diffs (rear with lsd additive) - have not drained the tcase but the fluid was never low (since ive owned it) and looks bright red - im thinking it might have something to do with the "hard drop after letting off brakes" issue that i have read about on a few archived posts but noone ever said whether or not it was fixed and what caused it to begin with

its almost a metal binding or grinding sound with the occasional pop thrown in - loud enough that i can hear it over the new muffler - maybe the cv going to the tcase? i dont know where to start...
