RE: Trailer hub bearing torque
I say "Did it that way for 20 years" because I no longer use a two nut system.
I have thrown every single two nut set away I touch.
They are an antiquated system that is no longer relevant as far as I'm concerned.
I advocate for, and recommend to everybody who listens or not to throw them in the garbage and opt for the Stemco Pro-Torq wheel nuts instead.
The repeatability of end play of these wheel nuts is incredible.
I replaced every single wheel seal & installed Pr-Torq's years ago.
I set them at 0.002". Not close, every single one was set at 0.002"!
I have 12 trailer hubs. I then went and loaded ugly as shi#t off the Houston docks.
At 187,000lbs, in over 110* temps on the very first load after I switched, I stopped 3hrs down the road to do a chain check and with my infrared thermometer, all 12 hubs were within 12*f! (It was less, but we'll go with that)
With that load every axle exceeded 20,000lbs. That's over 10,000lbs per hub!
That is repeatability!

I'm not a salesman, and I get absolutely nothing for recommending them. As firm as Rawze is about new ISX heads over reman, I am just as adamant about Pro-Torq's.
They will absolutely pay for themselves in time and provide a profit with tire wear, fuel economy, and reduced maintenance costs. The best part is, one socket. Yup, you can pack one socket and do your own instead of multiple sizes of sockets (with your own trailer of course).

The procedure for Pro-Torq's is stupid simple.
-lube bearings and threads with oil
-torque to 200 ft/lbs
-rotate hub 360*
-torque to 200 ft/lbs
-rotate hub 360*
-back off nut to finger tight
-torque to 100ft/lbs
-rotate hub 360*
-torque to 100 ft/lbs
-rotate 360*
-back off 1/8 turn
-install locking tab/ring
-verify end play
It will be 0.0015"
