Do u have any guide lines on how minutes turns to tighten from full lock?
Sorry bro... This is not like NTC3 ball diff.

Even after you follow them carefully, they still slip on the NTC3.
Anyway, just tighten the screw slowly (bit by bit like 5 minute turns) and hold the two rear diff halves and try to turn the rear diff pulley. Tighten the rear diff screw till the point when you cannot turn and rotate the rear diff pulley anymore. Then, use the grub screw on the other side of the diff to lock the setting so that the setting does not run.
