This is on my GMT250 btw (Buick Rendezvous)..
That being said, the ABS wire comes down the the front of the lower control arm on top. I will order up the Wheel Bearings, and when replacing it, I will pull the cover off the wiring loom, and run a hand over it and see what I feel.
Im also getting a code U1301. Likely unrelated, but I have a feeling its what is causing my dash random resetting.
You were right, I tore into it this evening, and found that the wire had fallen on the CV axle, and that the dealer (repair done before I owned the truck) had replaced the wheel bearing, and routed the wire in front of the bracket, instead of behind it, leaving the wire and its sheath to rub on the CV axle. Got it routed correctly, and no ABS lights on my test drive, hope it lasts for a minute. Although the bearing is cheap, money is tight right now.The wire harness on those is very short and there isn’t much clearance between the wire and the CV axle. It is pretty common for the wire to fall slightly and the CV axle rub through the wiring. That could be your problem and it is rubbed though just enough to cause an intermittent problem.
