105 ftlbs on a 62
Snap-On 1/2" impact. lol
That FAQ linked has 90, and that seems too low to me. I am in favor of the 105 ballpark, as new ubolts tend to stretch and need some re-tightening.
Always easy to know when things get a little loose as the front seems squirrely and leafs can clunk (though you can get that from other issues too).

well I cut off the excess threads on the old OME u bolts...got tired of hearing them get caught up on the rocks...and I'll check the torque a little later today if I get to it. I'm going with 100Lbs.
So I cut the excess of the ubolts to reduce crap the rocks can hit... and checked the ubolt nuts both front and back....all but two on the front were good, had to tighen the other two a little bit. On the back...different story...had 3 to 4 that were not up to torque spec and had to tighen them a good bit.
So good idea to check the torque on the ubolts.
Hitting the rocks a good bit probally did not help things, but the trails we go to...seem to have plenty of that up in TN.

Make that
Good to check torque on EVERY bolt underneath after playing in the rocks. Steering, suspension, driveshafts and mounting bolts are key with steering being the highest priority. Brake caliper bolts too! Will save you issues down the road.

I have owned 33 vehicles and BOTH of my wagons like to have the caliper bolts loosen sometimes!! Never have I ever had this issue with another vehicle. Had to tap both knuckles on Fiona and on the orange bitch I took a more extreme alternative after a knuckle failure. Never had an issue on my BJ42 tho.
Brake caliper huh?
I'll have to look into that. Thanks for the tip!

I have had this on my '85 pickup. The PO didn't help and used a larger coarse thread bolt. Going to replace that knuckle and have a machine shop redo it back to OEM threads, then keep it as a spare.
i say! tight as fxxx, then go take it wheeling and fxxxing tighten those fxxxing things up again to "tight as fxxx. cheers!

also noticed where I've done some serious rubbing on the lower portion of the shocks (mainly the rear two)...
I've not noticed any other stuff loose but agree it would be best to check obvious bolts/nuts associated with the driveline/steering. Not sure why brakes would be an issue..but the vibration/shock/wear while in the rocks sure is a lot more that you would ever see on the road.

I will agree with that but....
I don't go much over 100ftlbs. With a breaker bar it is easy to get them way over 100ftlbs and imho that is to much. I also check mine nearly everytime I am under the truck. When I am wheeling I give the underside of my truck a good look over several times during the day. Just good habits to be in...
