i took the .119 from the ring gear side and put it on the pinion side. so i have the .121 there now which tightened up the backlash and the .119 removed the same i added so preload stayed the same.

HOW TO: Rebuild the MK3 Rear Differential.
- Thread starter TurboStreetCar
- Start date
so got some miles on the diff and its working great! doesn't whine like it use to or sound like bolts in a blender like my broken one. the 3.73 seems to accelerate slightly slower than the 3.91 but you go a little faster in each gear so its hard to tell for sure. helped traction in 2nd some also seemed to drop spool 100-200rpm in 2nd and third when it hits full boost. i'm happy with the results :biglaugh:
