Leaf spring U-bolt toruqe specs?
It's on a 1986 F250 4x4 supercab HD w/ a D-50 front TTB axle. What do I torque the u-bolt nuts down to? The parts guy at the dealership said to get some of the green or red Loc-Tite to ensure those nuts don't move. Is that necessary?

Thanks! I'll shoot for 100lb-ft and give it a go, then re-torque as aforementioned.
I've never dealt with torques given in a range as with this truck. My other truck's torque specs are specified exactly, no ranges.

that parts guy must never have put new springs in.not only do you not need loc-tight.after a couple months,good look trying to take them off lmao.new U bolt time.
they're not going anywhere once torqued and driven for a little while.

they weren't cross threaded.that's how they come off.
iv never managed taking them off before with a ratchet/breaker bar,due to having access to a torch.
that must have taken you a while and a whole can of WD40(tho that probably doesn't actually help,im sure you must of told yourself it was.least i would have lol) i always wondered if they would keep turning off,or brake.
good job!
are you adding springs or just replacing worn out/broken ones?

oh i see.iv never tried that.i didn't think they would remain strong enough once you took them off.i thought they would be too stressed and couldn't be re-used.(in my case,as always,im in need of longer ones for adding springs anyway.so never mattered.)

I've always thought that too, but was told I could reuse them. When I did suspension work on my Jeep, I replaced my u-bolts because I thought they were stressed long enough. I should've just bought new ones and I would be a lot farther along now.
