Just replaced my upper arms with new ones both rubicon express . The new ones came with new bolts. Tried to tighten the first one to factory torque specs and it snapped. Went back to using the old factory bolts. Is this a known problem with there bolts or was I just unlucky.

 

Did you cross thread it?

 

no not cross threaded. screwed the nut on all the way by hand then torqued it down and it just kept turning until it snapped. i didnt even want to try to use the other one if they can't be trusted to be torqued down without breaking.

 

I had a leaf spring centering pin do the same thing. Sometimes you just get a crappy bolt, it happens.

 

The stock suspension bolts are much better and offer a higher rating. I prefer to reuse them if condition is good.
