not sure if i need one or not. everything feels ok except there seems to be more backlash than i would expect. i dont have a dial indicator to check it yet, but ill get one soon. its not much but it always popped when i put it in gear like it had a bad u-joint in it but they were good. carrier bearings seem tight laterally. axle bearings seem tight laterally. nothing leaks so seals are good. any tips on determining if i need to rebuild or not? if i have to rebuild i aint gonna have money for a locker. i really dont wanna run a miller locker on my DD.
