So if these were 3/8" and you went to 185 ft lbs, you way over tightened them and stretched them. Most after market u-bolts in the 5/8" - 3/4" range torque to 110- 150 ft lbs.

The tool is only as smart as the user. No matter how much is costs.

If they kept loosening up you have installation issues. You just proved the manufacturer's case.

How did you torque them and to what torque did you take them to?

185 ft-lb/tq for the hanger to shackle, shackle to spring front hanger and u bolts that's the spec ford provided me.
I think it was a stretch issue 1.7-2.1 inches in length and lost .0075-.0035 in diameter on a 3/8 u bolt they supplied the u bolts I may send them to a local place to have a hardness test performed for sh*ts n giggles because I doubt they are of grade 8 or similar strength. I used lake Erie bolts for the hanger and shackle hardware and have not had one issue yet I did the same for the front when I did those zero issues.

Regardless of the grade, if you torque it beyond its rating then its going to give.

Do you mean 5/8" instead of 3/8" ???? Actually SDtrucksprings.com sells you M16 u-bolts.... but that is basically 5/8"....

SEABEE08FX4 · Mar 17, 2015

So 110-120 ft lbs max.

yeah no crap this is the third time this has happened at this dealership when I ask for tq specs for the front they gave me 213 when it was only 99 granted these are print offs from there computer system.

Why don't you just google for superduty torque specs. I've done it and I get a sheet of every spec for every bolt.

Sperman shut the fvck up, you and the op are separated at birth twins

Clearly not. I haven't had this many recurring issues with my junk. I just say stupid chit. This guy probably shouldn't even work at jiffy lube.

**** i used a 1/2" impact on mine when we put the 8" BDS springs and PMF 3" 5* blocks on it. Ran the bolts down until they turned no more. ****ers haven't come loose since and i drive like the truck owes me money.
