Two problems related to axle hubs have been reported for the 1997 Chevrolet Tahoe. The most recently reported issues are listed below.
4-wheel drive: on dry conditions and at slow speeds, abs braking system activated, causing extended stopping distance which may result in a crash. Dealer said the problem was due to the front hubs wearing out which caused the abs brakes to malfunction.
Abs system comes on at low speeds without brake pressed-vehicle then is hard to stop and pulls to the right. I have replaced all pads and calipers. Machine bled system and replaced left frt speed sensor. Took to dealer and was told that the front hubs are exposed and most of the time tear apart and cleaning solves. Am upset the dealer charged a diagnostic fee for something he could have told me on the phone!.
