I have an 04 f-150 supercrew 5.4 4x4 and when I brake hard I can feel the truck shake some. It can be pretty bad when going down hills at higher speed. I have replaced the front discs and pads twice but the shake is still there. Any help would be greatly appreciated.

 

i would say your rotors are warped.

 

You replaced the rotors and the same shake is still there?? what you're describing sounds just like a warped rotor to me

if you don't torque your lugs evenly i believe rotors will warp? but im not positive. it does make sense though

 

Should I replace the rear rotors??
