Axle U-bolt torque

Lincoln versaillies rear housing, 1/2" fine thread u-bolts, how tight to torque them?

Re: Axle U-bolt torque

u-bolt is probably mild steel

Re: Axle U-bolt torque

I just added some threads to a set of OEM u-bolts and they cut like butter. I have threaded both grade 5 and grade 8 and it cuts differently. I would think aftermarket ones would be grade 5 or 8 but I am betting OEM units are unfortunately mild steel.

Re: Axle U-bolt torque

Torque them until you see the shock plate start to bend, then stop.

Re: Axle U-bolt torque

Are you sure they are 1/2" bolts?  Every Mustang or Versailles ubolt I have come across was 7/16" diameter.  If you torque that to same torque as a 1/2" bolt, you may have extra pieces that you cannot use.

Re: Axle U-bolt torque

Thanks for the replys.  They are 1/2" u-bolts, not the factory ones.  I'm using the TCP spring plates I picked up on here a little while back, they look pretty stout........better not  "tighten til I see them start to bend".

Re: Axle U-bolt torque

I got 1/2" fine thread U bolts with my Currie large bearing rear end. Their installation instructions specifies 45 ft lb. Torquing the four nuts to 45 looked like plenty of "tight". Considering the problems Tubo had with his first set of fiberglass springs not being tight enough, tight is good.
