    Can't find my Haynes book right now, and the 300 search results I looked at didn't help me, so...

    What's the torque for the u-bolts on a 10B rear axle?
    -I'm referring to the u-bolts that hold the axle under the leaf spring.

    "until tight"
    but seriously i used my 1/2" impact and hammered them down until they're tight.. criss cross pattern to make sure they're all torqued the same..

    If you think you can get 130 ftlbs out of a 5/16" bolt all the power to you. /forums/images/graemlins/rotfl.gif Actually, very little pressure is put on the universal cap by the strap. In fact, I've been known to use little pieces of aluminum to put more pressure on the cap.

    Okay, clear this up, are you talking about the u-joint strap or the u-bolts that hold the axle to the spring? /forums/images/graemlins/confused.gif /forums/images/graemlins/confused.gif /forums/images/graemlins/confused.gif

    Sorry... After re-reading what I wrote, I realized it's not clear what I'm asking.

    yeah, 130 ft lbs. would be a little much on the u joint straps. /forums/images/graemlins/rotfl.gif /forums/images/graemlins/rotfl.gif
