What did you figure out with the torquing of the ring gear bolts? The lock-tite and oil question.

The backlash was ck’d on the oem unit & was .004”
This was after draining fluid from diff, standing upright (pinion down) & removing rear cover...stub shafts still in place.
After re-assembling & dropping unit back in housing (new side bearings & thrust washers on same sides as they were removed from) & reading was .006” (this is with no oil coating on gears yet & stub’s not popped back in place).
Prior to putting new unit in, mike’d the thrust washers & ring gear side was a hair thinner than other side.
Removed bearing caps & raised unit up, then swapped sides of washers.
Backlash reading was .005” (pattern looked the same & this should snug up a tad after the 75/140 moves around in there).
The ring gear bolts are an odd size (m13x1.25)
Removing all loctite & cleaning up everything was a bit tedious, but got it right...after seating gear to unit; torqued to the initial ft.lb & then turned additional 35* while testing with torque wrench.
Was hitting the mark at 110ft.lbs.
Threads received high strength thread locker only (no oil
)
Had adequate tools to hold Wavetrac unit steady, while Madwi was hitting the final torque w/wrench (2-man job without clamping down Wavetrac)
Unit is built with 2 flats on each side, underneath side bearings (52mmx14mm) so holding steady with appropriate tools helped,,,but still took some umph to hit the mark with every ring gear bolt (criss-cross pattern)
PS: ring gear bolts were cleaned well, using anti-corrosion oil
