Steering Gear Box Problems of GMC Suburban

Repeated excessive wear on front brake pads and now on rear brake drums. We are very conservative drivers and typically get 80-100,000 miles on a set of brakes. This is our second set of front pads. We do tow heavy loads. The Suburban is equipped with a heavy duty towing package . It has already had the steering gear box replaced by the dealer. The front pads have been replaced once and the rear brakes have been adjusted, also the master cylinder has been replaced by the dealer. The brakes just do not seem of sufficient capacity to stop a vehicle of this mass towing load. We've owned Suburban's since 1973 so we do feel we have a degree of experience in this area. Finally when the vehicle is driven at highway speeds and a bump is hit, the entire electrical system shorts out for approximately 1/6-1/5 of a second causing everything to go dark. I suspect an exposure in a wiring harness. *****dimsii ivoq entry posted after 12/12/02 cut over to artemis****763731.

While driving about 40 mph steering column totally ceased, causing loss of control. Truck was towed to a dealership. Power steering gear was replaced under warranty.

Truck pulls when braking. Tbs fix implemented with little to no improvement. Last time at dealer, dealer said GMC has problem with 3/4ton Suburban brakes but doesn't have fix. Nothing he can do. Truck has had combination valve replaced, rear shoes replaced, front pads replaced (5x total), calipers replaced, rotors replaced, tie rods replaced, idle arm replaced, steering box and pitman arm replaced, front brake hoses replaced, control arm bushings replaced, and aligned several times with no fix to the problem. Braking at highway speeds it is very dangerous. You don't know which way the vehicle will go and how hard it will try to get there. As an engine designer I find it amazing that gm has a handling/safety issue of this magnitude. This is a big truck to have such a controlability problem. Please help. A shaull.
