i just bought a 95 cherokee and took it into the dirt today, when i put it into 4wheel and started to drive it sounded like gears grinding together. does anyone know what that might be. it seemed like the 4wheel was working but just making a horrible noise.

 

check all your u-joints up front, the ds u-joints, and the two axleshafts u-joints there should be no play. also, you can pop off your diff cover and move the wheels and inspect whats going on inside there

 

my buddies 95 did the same ting he was told it was the tcase one of the gears for the chain was worn or the chain was worn out anyways he replaced the tcase(had a spare) and the noise was gone
