I just had a car inspection for new tags and was told I needed new front wheel bearings on my 2000 chevy astro van. An ABS light flashed on once since the inspection but it went away. I shopped the price of $300 to do the wheel bearings and was told by another shop that it would be over $700 if I have ABS brakes. Why the difference in prices? Is there a way from the VIN number to tell if I have ABS brakes or just an ABS brake light signal in the dashboard display?
