8. Remove the left-hand side axle shaft by pulling the assembly out of the carrier and through the hole in the steering knuckle (spindle mount).

9. Remove the right-hand axle shaft by performing the following:

   1. Remove and discard the right front axle joint boot clamp from the outer axle assembly.

   2. Pull the right-hand axle shaft out of the axle joint boot and stub shaft and through the hole in the steering knuckle (spindle mount).

10. Inspect the seals on the outer axle shaft ends, and replace them if necessary. Replace the seals as follows:

    1. Remove the old seal from the axle shaft by driving them off with a hammer.

    2. Thoroughly clean the axle seal area of the shaft.

    3. Place the shaft in a press and install the new seal using the Spindle/Axle Seal Installer Tool T83T-3132-A, or equivalent.

To install:

11. Install the right-hand axle shaft as follows:

    1. Ensure that the rubber boot is properly installed on the carrier stub shaft. Slide a new outer axle shaft boot clamp onto the rubber boot.

The model 35 front axle does not use blind, or master, splines. Therefore, special attention should be made to ensure that the yoke ears are in line (in phase) during assembly.

12. Install the left-hand axle shaft by sliding it through the hole in the steering knuckle and engaging it into the carrier. Ensure that the shaft is fully seated into the carrier and engage to the splines inside.

13. Install the front disc brake rotor shield, spindle and retaining nuts.

14. Install the front brake rotors, bearings, locknuts and hubs.

15. Install the brake caliper and wheel assembly.

16. Lower the vehicle. Tighten the lug nuts to specification.
