Alright guys, I'm in need of some help. After 3 different rotors, New Caliper, New Pads, New rear Axle Shaft w/ bearings, studs and seals, balanced tires and rims were checked for major damage. I STILL have a violent shake in my rear end during breaking. I am going to try a trick that worked on my Z71 and pull the ABS relay to check my speed sensors tomorrow, but after that I am lost guys. Much help appreciated
