What is the proper torque spec for the strap bolts on the u-joints?

Thanks in advance for the help...

Keith,
I'm looking in my Haynes manual. It says ft-lbs. Man that is a big difference between in-lbs and ft-lbs. Does someone have a real GM shop manual that can check.

Keith,
Yeah I'm with you. RjVette should use your numbers. 18 ft-lbs seems reasonable now I think about it. The other numbers on the page make sense. I would agree that is probably a misprint.
I think I'll order that real shop manual now...

My 1985 GM Shop Manual says "22 - 29 ft-lbs" for the strap (trunnion) bolts on the U-Joints.

Thanks for all the helpful advice. I have to pick up a new bolt today to replace the one I broke. While I'm at the dealer, I am going to find out what the proper specs are.

In my research so far, it seems that the straps for the drive shaft are 22-29 ft lbs and the half shafts maybe 150 ft lbs. This still seems like alot.....


Thanks again,

I just updated my Haynes. It says Ft/Lbs for everything. The rest of the numbers seem ok. I'll chalk that up to a misprint.
And I'll go get the real service manual...

Have 2 good 6 point sockets before you start. preferably a Craftsman so when you break one you can get a new one.
