Re using U bolts for leaf springs

MilesnMiles · Post by **MilesnMiles** » Fri Jul 31, 15 11:01 am

Some of the yank sites get very excited about not resuming them. I'm fitting an add a leaf and want to reuse my u bolts. They were new three years ago and have been reused once before now. Any thoughts? Can't see why Mopar would fit parts that can't be reused.

I've reused old ones on many occassions, provided the threads are good and there's no serious pitting I wouldn't worry about it. In all my years in the trade, before disposable stretch head bolts came along, no one ever replaced a pefectly good bolt on anything, nothing fell apart because of it.

Cheers Blue, that's pretty much how I see it.

Chrysler ones have a nice waffle pattern to the inner

designed to allow you to do them up to a sensible 40 or 45 ft lb without the axle slipping or you kinking the axle tubes

if they have been mangled up to 70 80 or 90 ft lb

new will be necessary

45 ft.lbs. (+/-15) for 8-3/4" and Dana60 axles.
40ft.lbs (+/-10) for 7-1/4" axles.

spec for bolts that do not have the flattened section with waffle in the U may differ

Yes reuse if in good order. Hell, I've even cut them off with the angle grinder,welded them back together and used them again on my old Landrover

Might not sound safe but never had a problem.

yeah I'd expect higher for a U made from round material the full length

I,d have no problems re using, if not stretched !

Just check they haven't stretched by laying the threaded sections together,if they don't sit in each others threads, they have stretched, and in that case I wound not use them .
