I was just playing with my pinion angle and was doing a search here for u-bolt torque. The responses varies so I did a search at Eaton and Landrum. Landrun says max 45 ft lbs for 1/2" grade 5 u-bolts and Eaton says 65... I guess I'll be somewhere in the middle

I'd go around 65 and make sure you retorque them 1000 miles later

Thanks for the reply Joe!

This link may help as well, for anyone else wondering. I used 90 ftlbs on my Hotchkis 9/16 U bolts

With polly or rubber pads how do you get a good torque reading?

Dennis, I'm not sure because I didn't use any of the pads that came with the kit.

I have a poly pad between the spring perch and the leaf spring, so I'm only squeezing one pad per side. I did mine to 60 ft lbs. last night without any problem. I can see rubber being an issue, possibly even with 2 poly pads per side.
