About a year I ago I had a recall on my 2000 GMC Sierra SLE 4X4. The recall
involved corrosion build up on the mounting surfaces of front ABS wheel
speed sensors. When coming to a stop the ABS would engage causing the
vehicle to roll farther than anticipated. I had the repair completed. Now a
year later the same problem that the recall was suppose to address has
occured again. I returned it to the dealer, told them about my problem. They
said that there could be another cause to this problem. They had to check it
out. They hooked a scan too up and could not duplicate the problem. It cost
me $34 cdn for nothing. Now the problem occurs nearly evertime I pull up to
a stop. Anyone else have this problem?
Well....that was a year ago. Perhaps it's the same problem again, or
maybe it wasn't cleaned as thoroughly as it should have been. In any
case, I'd start there again. You may also have a defective front wheel
speed sensor. If it does it almost everytime you stop, it should be
quite visable on a scan tool. Just ask them to monitor the wheel
speeds as you come to a stop....you'll see the offending wheel go
to zero miles/kilometers before the others.
Thanks Ian. I suspect that it wasn't cleaned properly the first time. First
when I took it back to the dealer, it had only happened once to full
capacity (when you actuall hear the ABS kick in). Sometimes I could barely
feel the ABS brake pulsations. Now it happens more often to some degree,
almost all the time. Maybe I'll give it a good cleaning myself and coat
mounting surfaces with a thin coat of anti-sieze and see how that works out
before returning to the dealer.
