how much "clunk" does your detroit locker have? i'm pretty sure its normal operation but i would like to know if yours has it too. like when you let off the gas and it down shifts as you slow down and it kinda clunks. or when youput it in gear and it clunks. or if you let off the gas and go into a cost and hit the gas agian it clunks alittle. i think detroits web site says its normal. because of backlash built into the locker itself. on mine i did it myself soiknow the back lash and all for the gears is good. i checked it like a thoudsand time before i put it back together and this same unit was inmy silverado and did the same thing.

mine doesn't clunk much that i can tell...but there is also a little bit of slack elsewhere in my drivetrain. It is normal tho, what you have.
