Please Help Got the shakes

[roy c]

I have a 93 K2500 sub that I replaced the front rotors pads
rear drums shoes bearings when I apply the brakes shakes very bad
rotated tires same thing took drums and rotors back exchanged
same problem new steering damper no change I have anti lock brakes
and hydro boost any idea's I noticed that it came on I think slowly
because all the snow on long island this past winter I thought there may
have been a chunk of ice stuck in the rim but problem still there

jack the front end up and wiggle the wheels side to side and every which way to see if your tie rod ends or pitman arm is worn out

forgot to mention inner and outer tie rods are new ball joints are tight
bushings also tight could the new rotors be warped

That's definitely possible! Have you checked your pitman arm for wear? I can tell you I know nothing about hydro boost setups, so I don't know if it could cause any problems in that system.

In the 4x4's, your leaf spring bushings can be bad and cause the shakes too.
