One problem related to air brake wheel speed sensor has been reported for the 1998 Chevrolet C/k Pickups. The most recently reported issues are listed below.
Normal usage of truck, hot or cold, happens about 20% of the time. When coming to a stop, at about 5mph, the abs turns on and incresses the stoping distance. No damage yet but this weekend I came much too close to hitting a family crossing the street. I have not driven the truck since but after doing some research I have found there is a TSB #634839, for 99-02 silverados with this problem. It states dirty wheel speed sensors or sensors out of range. I will be folowing the directions there to attempt to repair my 98 silverado. I am not positive but I believe gm of canada has already recalled affected models to repair this problem. There is no abs light or codes stored. . Read more...
