    I wouldn't go more than 25 or 30. I usually just snug mine enough to squeeze the rtv out.

    That jeep thing? Yah I understand it....... Like my Blazer? <a target="_blank" href=http://community.webshots.com/user/blazerk5>http://community.webshots.com/user/blazerk5</a>

    The 1987 GM factory manual lists it as 20 ft/lbs for the 10 bolt axle. [​IMG]

    But then again, I've never used the torque wrench on the cover bolts. [​IMG] I just give the RTV 20-30 minutes to skim over good, then put the cover in place and lightly snug up the bolts. I come back an hour or more later and tighten up the bolts firmly and fill 'er up with oil. This gives the RTV plenty of time to harden so it won't squeeze out when the bolts are tightened. [​IMG]

    I believe in torqing the diff cover bolts to factory specs. The cover is designed as a part of the axel. When properly torqued it provides added support and helps to keep the housing from distorting under heavy loads. A 10 bolt needs all the support it can get so it should be torqued to factory specs.
