2.

Loosely install the new flange bolt (C).

1.

Loosely install the new damper mounting bolt (A).

1.

Raise the rear suspension with a floor jack to load the vehicle weight.

2.

Tighten all mounting hardware to the specified torque.

1.

Install the brake hose mounting bracket (A).

2.

Install the wheel speed sensor (B).

3.

Connect the brake line (C) to the wheel cylinder.

NOTE:

1.

Make sure the brake fluid level in the reservoir tank (A) is at the MAX (upper) level line (B).

2.

Start the bleeding at the driver's side of the front brake system.

NOTE: Bleed the calipers in the sequence shown.

3.

Attach a length of clear drain tube (A) to the bleed screw (B).

4.

Submerge the other end of the drain tube into a clear plastic catch bottle of brake fluid (C).

5.

Have an assistant slowly pump the brake pedal several times then apply steady continuous pressure.

6.

Loosen the bleed screw slowly to bleed the fluid into the plastic catch bottle. The brake pedal will travel toward the floor as the fluid is bled from the system.

7.

When the brake pedal reaches the floor, have the assistant hold the pedal in that position, then tighten the bleed screw. The brake pedal can now be released.

8.

Check and refill the master cylinder reservoir tank to the MAX (upper) level line. Be sure to reinstall the master cylinder reservoir cap.

9.

Repeat steps 5 thru 8 until the brake fluid in the clear drain tube appears fresh and there are no air bubbles in the fluid.

10.

Repeat this procedure for each brake in the bleeding sequence.

1.

Install the rear wheel.

NOTE: Before installing the wheel, clean the mating surfaces between the brake disc or the brake drum and the inside of the wheel.

For proper inspection and adjustment of the wheel alignment, do these checks:

1.

Release the parking brake to avoid an incorrect measurement.

2.

Make sure the suspension is not modified.

3.

Make sure the fuel tank is full, and that the tire repair kit, the spare tire, the jack, and the tools are in place on the vehicle.

4.

Check the tire size and tire pressure according to tire information.

Use commercially available computerized four wheel alignment equipment to measure wheel alignment (caster, camber, toe, and turning angle). Follow the equipment manufacturer's instructions.

1.

Check the camber angle.
