I bent my axle housing causing the locker to not engage properly, ran it for a little bit and caused some damage. Might work fine in a straight housing, not sure, but for the price it may be worth the gamble. The teeth show a little wear and the pins are chipped a little. Might just need new pins and springs.
Specifics, dana 60 spartan lunch box locker, 35 spline, about 1.5 years old. Worked great up till I bent my housing.
