U-Bolts???? T-I-G-H-T

YA, I use my BEEFY Impact wrench to take off and install leaf spring U-bolts. I once had one loosen up. It angled back put tire into rear of fender opening, and shaved off the leaf pack pin. Thats a job to replace that pin with a bolt and grind it down to fit in the little hole in the axle. So yeah go TIGHT on those bolts. Lock washers and nylon lock nuts for sure!!

110lb for the spring eye bolt to the frame and the one for the shackle

Again I used the impact wrench!!!

110 for the spring eye bolts? holy crap... I use locking nuts and probably put about 30 ft/lbs on them... is that 110 number an actual spec from a real source? sounds more like a u-bolt spec to me...

That just had that happen to me, had to fix it on the trail. I'll be putting the impact on those things after I get one.

Ya its fun trying to compress your leaf springs back together using a C-clamp and putting a new bolt and nut through center hole, and then grinding it to fit the hole in your axle. But my CV driveshaft with 1350 U-joints held up to the axle being way outta whack. And its a good thing local law requires I have mud flaps or the fender would have torn up my tire and that wouldnt have been pretty while cruisin' down the highway!!

That's more like it, 110# would crush the hanger into the bushing badly and create a very stiff ride.

Tighter than this...

110 lb is right out of the manual for a 1980 k20 just replying what the book says
