REMOVAL & INSTALLATION

Disc Brake

When replacing the front hub bolts on vehicles with anti-lock brakes, remove and replace only one wheel lug stud at a time to avoid misalignment the speed sensor exciter ring.

  1. Raise and support the front of the vehicle safely using jackstands, then remove the wheel.
  2. Remove the brake pads and caliper. Support the caliper aside using wire or a coat hanger. For caliper removal and installation details, please refer to Section 9 of this manual.
  3. Remove the outer wheel bearing and lift the rotor and hub off the axle. For wheel bearing removal, installation and adjustment steps, please refer to Section 1 of this manual.
  4. Remove the retainer bolts securing the hub to the rotor hat, and separate the components.
  5. Support the hub, then drive the stud out using a hammer or an arbor press or stud removal clamp.

To install:

  1. Clean the stud hole with a wire brush and start the new stud with a hammer and drift pin. Do not use any lubricant or thread sealer.
  2. If necessary, finish installing the stud using a press or stud installation clamp.
  3. Install the hub to the rotor using new bolts.
  4. Install the rotor on the vehicle, and adjust the wheel bearing.
  5. Install the brake caliper and pads.
  6. Install the tire, then remove the jackstands and carefully lower the vehicle.

Drum Brake

  1. Raise and support the vehicle safely using jackstands, then remove the wheel.
  2. Remove the brake drum. Refer to Section 9 for drum brake removal and installation steps.

WARNING!!!
Do not hammer the wheel stud out to remove it. This will ruin the wheel bearing.
  1. Attach a stud removal clamp to the stud and press the stud out.

To install:

  1. Clean the hole with a wire brush and start the new stud into the hole. Do not use any lubricant or thread sealer.
  2. With the stud straight in the mounting hole, complete the installation using a stud installation clamp.
  3. If a stud installation clamp is not available, stack 4 or 5 washers onto the stud and install the nut. Tighten the nut to draw the stud into place. It should be easy to feel when the stud is seated.
  4. Install the brake drum.
  5. Install the tire, then remove the jackstands and carefully lower the vehicle.
