Re: How to disable ABS and is that bad?
The only thing on the hollow spindle itself that is ABS-specific are the two notches that allow the ABS sensor to reach in. It has two notches so the same spindle part can be used as left or right side. The part that the ball joints attach to that holds the spindle (the knuckle?) has the hole for the sensor. And the knuckle has a screw (small 12 pt. on mine) that goes through the knuckle and into a small metal piece that overlaps the spindle rim to help hold the sensor in alignment. If your spindle got eaten up, and you have a non-ABS type spindle in their as a replacement, maybe just cutting a notch in the proper place will allow the sensor to fit through. But you would still need the toothed ring (tone ring) on the hub/rotor to make it work.
Hmmm... maybe that's what you meant after all, that you don't have the tone ring anymore!
I couldn't figure out how bad wheel bearings would eat up the knuckle!
