I'm installing my 4.56 gears in my XJ, D30 front and 8.25 rear.
8.25 went in fine, minus the notching of the pin. .005 and perfect pattern.
d30 went in fine using the short pinion gear set from a TJ, however, I can't get the ring gear to move in tight enough against the pinion. My preload is set perfect on the pinion and I pulled out the factory shims on the carrier to start setting my backlash. I shimmed it as much as i could on the left to get in in against the pinion but I still have a full dials movement on my dial indicator. (So much i didn't bother to record the amount)
Anyone run into this issue before? Do i need to go to a new carrier?
