Rich , I believe there is a special coverage for the wheel speed sensors you can check with your local GM dealer as it varies year to year. We clean and apply a compound to the knuckle so rust doesn't redevelope. John, good deal testing this stuff is not hard at all, but does require a few items, sounds like you're on top of it. Joe Oh and sorry bout that wrong resistance spec, I was shooting from the hip on that, which is the spec GM uses withtheir sensors must have got stuck in my head.
