I did a lift kit on my 07 when it had like 3k or 4k miles. am dropping the lift very shortly. Can I reuse my factory Ubolts? I was planning on torquing them to spec... which by the way, what is U bolt torque spec? I've reused Ubolts on many 4x4's before... and never had issues. I always torque usually to 100# and then retorque in a few weeks to check.
Re-Use U-bolts? any ford techs?

Ford says to change the ubolts, but I know a LOT of people that reuse them without issues. I think you're fairly close on the torque. Maybe one of our good tech's will chime in with the proper torque.

Use new U-bolts. The amount of torq on those bolts could stretch and weaken them. When you remove them you should always replace them with new ones.
WOW. 185 Lb/Ft of torque. I might try and ask the dealer when I buy the U bolts... let me rephrase that. If he won't give me the torque specs, or print it, or let me see it on the computer/book... I WON'T buy the u bolts from them. That makes more sense. But i'm going to put the truck back to stock and drive it around for a week or 2, let things settle and then check the driveline Angles and see how much shimming if any I need or what the deal is. b/c stock I had vibes, lifted I have vibes.... sucks. and I know currently my pinion angle is off 4-6*. I'm very good at setting up driveline angles, but it's hard when the truck is so dang heavy and big, and you don't have time lately.
