Conmet preset hubs

I'm currently replacing the steer axle wheel bearings on my Cascadia and am getting some conflicting info about the bearing torque prior to checking endplay. Maybe someone has come across this before.

I have a Meritor MFS-12143a steer axle according to my info tag on the dash. When I search the letter/number combination on the rear of my hub, I'm coming up with a Conmet hub. There is a sleeve between the inner/outer bearings, but here's the curveball. .. It's using an AxiLock 2 1/8" nut. The other specs I have been given elsewhere do not use the AxiLock nut.

Here's the question...do I go off Conmet, Meritor, or AxiLock's torquing sequence? I would think AxiLock, but the final torque is drastically different with that nut. Initial torque is 200lb/ft with the final at 75lb/ft. Other Conmet sleeved hubs have much greater initial and final torque values.

Front Comnet Sleeved hub bearing sets get torqued to 225 ft-lbs (+ any necessary clockwise only rotation to get to the next locking position for the nut) and left there. They DO NOT GET BACKED OFF!.

-- Only non-sleeved hub bearing sets get backed off of.

After final torque, make sure you can spin the hubs by hand. Should have a tiny bit of resistance (a couple of extended fingers should turn them) but not hard to turn by having to use your whole hand.
