Just purchases my k1500. The truck had been rolled and has some minor cosmetic damage. The frame is bent so one side of the rear bumper is higher. The wheels seem to be straight though it pulls hard to the right. The steering is hard to turn, power steering with ABS assist, and slips or rather has a dead spot in the turn. The ABS light goes on and off with the ABS actuating in turns, usually a hard left. Though this varies and is getting worse. The front-left wheel jumps between 40 and 55 depending on if going up hill or down. The right-front caliper looks to have been replaced. The fluids are fine with no leaks found. The ABS cables have play and are not being pulled. There are no noises. Don't know where to start.
