[V8] Re; rear diff lock?

[Kneale Brownson]

ABS sensors read teeth on the axle.  The latter can be corroded with rust.
This can be cleaned out with a wire brush, but if I remember correctly, you
need to pull the housing off the axle.  ABS sensors are installed against a
shoulder in their housing, and if they were pulled and replaced without
cleaning out the housing, you could get some collected corrosion holding
the sensors a bit off the shoulder.
