Removal & Installation

  1. Raise and support the vehicle safely.

Brake linings may contain asbestos. Asbestos is a known cancer-causing agent. When working on brakes, remember that the dust which accumulates on the brake parts and/or in the drum may contain asbestos. Always wear a protective face covering, such as a painter's mask, when working on the brakes. NEVER blow the dust from the brakes or drum! There are solvents made for the purpose of cleaning brake parts. Use them!

  1. Remove the wheels, and brake assemblies.

Refer to Section 9 for the proper procedures concerning brake removal.

  1. If equipped with Command-Trac, connect the axle shift motor vacuum harness.
  3. Matchmark the front driveshaft and yoke.
  5. Disconnect the stabilizer bar, rod and center link, front driveshaft, shock absorbers, steering damper, track bar and ABS sensor if equipped.
