The procedure is similar for both ford and Lincoln car models:-----

The details to replace Rear drive Axle Halfshafts are as follows: ---------

Removal & Installation



  1. With the vehicle in NEUTRAL, position it on a hoist.
  2. Remove the rear wheel speed sensor.
  3. Remove the inner and outer rear wheel hub nuts. Do not discard at this time.
  4. Remove the brake caliper hose bracket bolt.
  5. Remove the rear brake disc.
    NOTE
    Suspension fasteners are critical parts because they affect performance of vital components and systems and their failure may result in major service expense. New parts must be installed with the same part numbers or equivalent part, if replacement is necessary. Do not use a replacement part of lesser quality or substitute design. Torque values must be used a specified during reassembly to make sure of correct retention of these parts.
  6. Remove and discard the upper arm outboard bolt.
  7. Lift the upper arm from the knuckle.
  8. Support the lower arm and remove the lower shock nut and bolt.

To install:
  1. Install a new 1.102 inch (28 mm) circlip on the stub shaft.
    NOTE
    Make sure the oil seal protector is correctly aligned with the differential oil seal during installation.
  2. Using the Axle Seal Protector, install the halfshaft in the differential.
  3. Install the stub shaft in the rear drive unit. Make sure the circlip locks in the side gear.
  4. Slide the outboard CV joint down through the knuckle.
  5. Position the halfshaft outer CV joint through the hub bearing.
    NOTE
    Do not tighten the front wheel hub nut with the vehicle on the ground. The nut must be tightened to specification before the vehicle is lowered onto the wheels. Wheel bearing damage will occur if the wheel bearing is loaded with the weight of the vehicle applied.


    NOTE
    Apply the brake to keep the halfshaft from rotating.
  6. Position the halfshaft in the hub and use the previously removed inner hub nut to seat the halfshaft. Tighten to 203 ft. lbs. (275 Nm). Remove and discard the hub nut.
  7. Position the upper arm outboard end and install a new bolt. Tighten the bolt to 111 ft. lbs. (150 Nm).
  8. Position the lower arm and install a new lower arm bolt and nut. Tighten to 111 ft. lbs. (150 Nm).
    NOTE
    The wheel hub nut contains a one-time locking chemical that is activated by the heat created when it is tightened. Install and tighten the new wheel hub nut to specification within 5 minutes of starting it on the threads. Always install a new wheel hub nut after loosening or when not tightened within the specified time or damage to the components can occur.


    NOTE
    Apply the brake to keep the halfshaft from rotating.
  9. Install the 2 new rear wheel hub nuts. Tighten the inner hub nut to 203 ft. lbs. (275 Nm). Tighten the outer hub nut to 129 ft. lbs. (175 Nm).
  10. Install a new rear toe link bolt and tighten to 148 ft. lbs. (200 Nm).
  11. Install a new stabilizer link upper nut and tighten to 26 ft. lbs. (35 Nm).
  12. Install a new lower shock absorber bolt and tighten to 85 ft. lbs. (115 Nm).
  13. Install the rear wheel speed sensor.
  14. Install the rear brake disc.
  15. Install the brake caliper hose bracket bolt and tighten to 133 inch lbs. (15 Nm).
  16. Install the tire and wheel.


These details will help.
