Hi:
It is hard to do at home. I usually take my entire front hub assembly to a machine shop and have them remove and replace them for me, if it is a front wheel drive car, and in your case, if you have a Mustang, I am not sure if you can do this, as I know mine are pressed in place. If you can remove the whole assembly, I would ask for help!

Wheel bearing don't have torque specs (to the best of my knowedge). They have a procedure - in this case it is....
1. With everything clean and packed with grease, snug the bearing lock nut until it stops.
2. Reverse it about 1/8th to 1/4 turn and insert the cotter pin.
Done

I own the 2002 Buick Rendezvous CX and I've encountered the same problems listed here. The ABS / Traction Control Lamp stays on and was throwing a code for the left wheel speed sensor as well as an anti-lock brake code (both in the wheel bearing hub assembly). I replaced the left and right front wheel hub assembly yet this did not eliminate the abs codes. 
Ultimately, I traced this problem to a break in the wire that leads to the left hub assembly. Although the sensor was properly connected, the wire (which is encased in a plastic housing) was broken. This is the wiring which leads from the abs wiring harness under the hood down to the left wheel abs sensor. 
I would suggest that you simply remove the left wheel and inspect the wire that leads to the abs sensor (there is only one wire on each wheel). Mine literally fell apart when I removed the plastic housing around the wire. I spliced the wire together and put it back in the plastic housing. After this, my abs codes disappeared and my anti-lock brakes began working again!
This is a simple fix that many people spend $1000 + on by replacing the hub assembly which does not fix the problem.
