just like the title says.

what is the torque spec for the leaf spring u-bolts on the rear axle?

 

under 8500 lb gvw is 75-100 ft lb, over 8500 gvw is 150-210 ft lb

 

thanks

 

you'll want to keep checking them for a few times after you drive the truck too.you'll notice they'll take a few more turns after some miles going down the road.

 

i will make sure to check them.

 

i got everything back together yesterday. i went for about a mile drive yesterday and checked the nuts and they were a bit loose. how many times should i recheck the torque on them? kind of sucks having to take the tires off to check them.

 

i keep checking them about 10 times.once after about 20-30 mile trips for good measure.it's probably over kill,but it doesn't hurt to make sure lol.
i can simply reach around to check and snug up if needed.
i just added another aux spring to my packs.man i love it! just what she wanted.she stays up nice and pretty when hauling now.

 

i wish i could get them with out taking the tires off.

 

Why do you take off the tires?

 

Did you have to take your springs to the spring shop to add the extra spring?

 

i just went to traction (HD parts store) and bought another f450 aux spring with new center and U bolts.

 

Can you post pics I want to add a spring to my rear

 

I'd keep checking the bolts until they stop loosening up...

 

sure.here ya go.

 

Aah I see thanks for the pics. I just called the spring shop they quoted me $440 for the aux kit (brackets $40 per side, springs $180, and u bolts $10 each) is that a reasonable price? It is $270 to have my springs flexed and add a leaf maybe that is the route I will go.
