Second set of disc brakes since I have owned this truck. I have replaced everything from the hub out on both sides: rotor, caliper, and brake pads. I still get lots of noisy clanking from the front brakes when under way,especially if I hit a bump or hole in the road. A little pressure on the brake pedal and "wa-la" no noise...???????
Driving down highway and cruise control just quits. During those faults the left turn signal also does not work. Switch off and back started again usually fixes the problem?????

When I turn the key on the ON position the lights on the 4wd selector switch the buttons come ON then go OFF. Then the SERVICE 4WD light comes on. None of the buttons responded. I have another 04 gmc sierra 4wd I took the tccm and put it in and still the same lights come ON when turn the key on then go out and no response when I push the buttons. I replaced the encoder ring and same thing. I swapped out the 4wd selector switch and still nothing the only thing i haven't tried is replacing the transfer-case shift motor or the front axle actuator. I also cleaned the grounds on the frame that are underneath the driver door. i went to a couple shops and they want $150 - $200 just to hook up the scanner and diagnose the problem.
