The vehicle is raised and supported on steel jack stands, and the wheel and tire assembly is removed.
Stabilizer bar links are detached from the shortarms, if applicable. ABS wiring to the wheel speed sensor, if routed along the arm, is disconnected.
Shortarm mounting bolts are detached from the frame and from the axle carrier if the shortarm is in the rear.
For front shortarms connected to the steering knuckle via a ball joint, the nut is removed from the ball joint stud and the stud is pushed through the steering knuckle to free the arm.
The new arm is installed using new mounting bolts if required by the service manual. In many cases, the fasteners must be tightened with the vehicle weight on the suspension in order to ensure the bushings are in a neutral, or resting, position.
The vehicle is lowered and road tested to confirm the problem is resolved. Replacing a shortarm will change the vehicle alignment settings and the mechanic will refer you to a professional alignment shop to have the vehicle alignment set to factory specifications.
