Having problems with your 1998 GMC Safari ?
Steering shimmy when brakes applied
\015 When driving at highway speed and brakes applied steering wheel pulsates left and right\015
It sounds like either warped rotors or grease/oil on the pads. Jack up the front and pull the wheels off. Turn the rotors by hand to see if the rotors turn freely, then drag, then turn freely. If there is no grease or oil on the rotor surfaces, you need to either turn or replace the rotors. The job is a royal pain in the ****, so you may want to take it to a reputable shop.
