Hi All,
Hoping to have my G299 4.1 Torsen overhauled with new bearings, however wondering what the service specification are for preload, ring gear backlash.  I dont want to rely on shop guestimates, would it be possible that they could make an educated guess?

Without the JZA70 specs, would the MK3 TSRM for standard diff be acceptable given the carrier is probably the same?  The MK4 is a T2 Torsen, wonder if this is close enough?
