    Anyone know the torque spec of the six (6) bolts that hold the pinion bearing retainer housing to the diff?

    Thanks in advance.

    Those bolts are to be torqued down to 65 ft. lbs.

    Hey, I checked Haynes and my GM service manuals, the only thing even mentioned is pinion seal retainer ring and cover at 35 ft lbs. Picture looks right, but not sure so I checked my rear. It was from Boyce at a most of them loosened at 40 or so and had lock tight on them. Hope this helps and sorry for the amatuerish answer.

    K30Guy, where did you get the 65, as I figure now I am going to re lock tight mine and put them at 65. Thanks for info.

    I have the GM service manuals. I got two of the same year and they are VERY informative. They list EVERY torque spec for anything you need. I got these books free, but when I went down to GM dealership to try and get a specific year, they gave me a price for one book and I turned around and walked out the door!!! I won't quote the price, but if someone REALLY needed one of these books for themselves, then they should go get one. I wouldn't have anything else but these books.
