I have a 2000 Blazer 4WD a year or so ago I replaced the front wheel bearings with VSS included when I Was done I had a problem with the ABs activating at low speeds with no fault on the dash this is a dangerous condition recently I changed the speed sensors in the bearings first the Drivers side and had the same condition when test driven then the passenger side but when test driven and braking I now have aerror light on the dash could this be a bad bearing ? before changing the vss no error
