You might think about contacting Source Engineering, one of the manufacturers of replacement trailering arms. See if you can buy the u-bolts and nuts from them and ask about the torque specs. They may have used the OEM u-bolts when the arms were replaced.

Same here. Same rig and no problems with replacement arms which now have 60000 plus miles on them.

anther email from source engineering, dont worry about the spacers being loose. They dont use them at all now. So I continue to look for a shop that will work on it. Mr D, the replacement arms look like source engineering product, I have paper work from the shop that installed them but not the info on which arms were installed. I will try to contact them on monday and see if they have the recordss from 3 years ago. Soource engineering states that the U bolts TQ is 400 Ft lbs. none of my tools go up that high. maybe I should get a new pair of bolts from them and find a shop to change out the side I am having problems with and keep the removed pair for emergency.

I don't know about what you are working on, but I do know that in general U-bolts are hard to get tight in one shot. Tighten, them. But in service, and recheck. As the bolt distorts to fit the exact shape you need to tighten to keep parts from moving. And a loose bolt, that lets parts move is likely to break...

Agree proper torque and recheck is critical. You should be able to tell if the arms are from Source. Look at their online pictures and compare to yours. They are different than OEM including Monaco failed attempt of replcements.
