What's the recommended torque spec on the housing bolts? Tighten in a "star" pattern like on a wheel, or just go around?
How about the spec on the nuts holding the diff to the subframe?
The bolts holding the drive shaft?
And finally, the bolts on the bastard PPF?
Any loctite needed for any of the above?
Thanks,
Torque specs for diff assembly and reinstallation

Good question Kyle...
Hope someone chimes in with an answer as my new Torsen is ready for install in my '91....I suspect I will have to check out the torque numbers
in my shop manual and see if all those items are mentioned. Also interested in whether some type of thread locker is needed. I would guess the blue stuff.....

Hopefully this will help it is from the Factory Manual for a 1994:
Housing bolts 17 - 20 Ft Lbs, doesn't mention torque pattern
Diff to Subframe - the center bolt is 61 - 72 Ft Lbs, the two outter bolts 13 - 20 Ft Lbs
PPF has a several as follows:
Tranmission bolts 77 - 91 Ft Lbs
Differential bolts 77 - 91 Ft Lbs
Transmission support bracket on PPF Big bolt 77 - 91 Ft Lbs, Smaller bolts (2) 27 - 40 Ft Lbs

Thanks for the info. Any suggestions for loctite? I'm guessing on the ppf bolts at least.

Kyle,
We dont use loctite on any of the bolts in question, but do check them before every race and have never had an issue with them being loose.

Thanks, Greg. One other question occurred to me last night--when sealing up the housing with RTV silicone, do I err on the side of getting some in the thread holes? Seems to me if I get too cute about keeping it out of the holes, I might open myself up to leaks.
