Lug torque & socket size

[zippo]

On a 2007 Ford F 53 motorhome chassis with 22.5" wheels, what is the correct lug nut torque and what size socket??

450 ft pounds, and 1 5/16" socket

Anyone have the specs for the 22k F53 chassis with 19.5 wheels?

For my '99 F-53 with 19.5" it's 150 lbs. Big difference between the 22's and 19's.

For the 22,000# chassis it was originally 140# as stamped on the end of the lug nut, but Ford came out with a TSB raising it to 150#. Be careful at tire shops to point this out. I had all the studs on the right rear shear off. I am sure it is because they probably torqued them to 350# or more. The only thing that saved me is that they are hub centered and didn't come off the hub.
