Steering Wheel Shakes when Brakes are Applied
Troubleshooting Procedure
A. Check for Front Brake Rotor Run Out: Front
brake rotors can warp when in heavy use. This is caused by extreme heat created
by friction and pressure applied to the front brake pads and rotors. A heavy braking
condition can be caused by driving down a long grade or extreme driving conditions
such as racing. When a brake rotor becomes warped it will cause the steering wheel to shake when
the brakes are applied. To inspect for this problem rotate the brake rotor by
hand. The brake rotor should move freely, but with some resistance and turn for
360 degrees without hard spots. If the brake rotors are warped it is recommended
to replace them. It is possible, but not recommended to re-machine to the rotor
(the rotor will
be straight but it will have less mass to dissipate heat therefore re-warping
is eminent).
Front Brake Rotor, Brake Pad and Brake Caliper
B. Check for Lower Ball Joint Wear:
If the suspension lower ball joints are worn it will cause the spindle to wander
causing the steering wheel to shake. Lower ball joints are a normal service item
and need to be inspected every 40,000 to 60,000 miles. To inspect lower ball
joints use a flashlight and have someone help you by turning the wheel slightly
(jog) back and forth. If excess movement is observed in the lower ball joints
replacement is required.

C. Checking Idler Arm and Tie Rod Ends:
The idler arm, pitman arm and tie rod ends are normal service items and need to
be inspected between 50,000 and 80,000 miles. To inspect the idler arm, pitman
arm and tie rod ends, have someone help you by turning the
steering wheel slightly (jog) back and forth. If excess movement is observed
from any of the
steering
components replacement is required
