I think the main problem they broke was the first time it happened I didn't have the U bolts tight enough. I listened onlined and cranked to 80-100 lbs with a torque wrench. Don't do this, just get the U bolts good and tight and you're good to go. Especially with pinon adjustment plates. Mine were steel and @ 8 degrees.

|doodah||I used grade 8 cap screws (I think that is what they are called) that I got from Lowe's. They are round and have an allen head, plus they are just a little bigger (head wise) than the original pins were.|

If you've got a lot of free time on your hands you can slightly oversize your center pin holes in each individual leaf and run the larger diameter 3/4 ton center pins. After a couple hours with a round file(good luck drilling spring steel) and upgrading to the larger center pins, I never had another problem.
Also, when you're torquing you're U-bolts, make sure your spring plates aren't just bending. I've seen inadequate spring plates made out of 1/4" flat mild steel that just bend without achieving the appropriate clamping force.

Don't just tighten them, use a torque wrench. Do not use an impact either, use a torque wrench. Find out what the spec is from a service manual.

If the ubolts are too loose, the axle will walk around and snap the head off the bolt.
Also throw a spare in your tool box for the next time it happens on the trail.

How exactly does one go about breaking a centering pin while driving? Definitely need to torque your u-bolts down to spec.

|oldjeep||Or just take a grade 8 bolt that fits the spring pack hole and grind the head round.|

|Strepz||what torque value should I use? I had them pretty tight before.|

Go to the 4x4 shop or speed shop for that matter and buy replacement center bolts. Make sure you torque your u-bolts to prevent this in the future.

broke leaf spring center pin
I have a procomp 4" SUA lift. Going down a dirt road aproching the trail head I broke the center pin in one of the rear spring packs. A new spring pack is out of the budget right now and kinda a waste because I plan on doing a SOA conversion in a few months. How to I repair the broken spring pack? It has all the leafs, just need a new center pin.Thanks
