DEALER RESPONSIBILITY
Dealers are to correct each vehicle falling within the range of this campaign that enters the service department. This includes vehicles purchased
from private parties or presented by transient (tourist) owners and vehicles in a dealers inventory.
SERVICE PROCEDURE
NOTE:
^ Photos in this procedure are of the left rear axle. The right rear axle is a mirror image.
^ Make sure to perform this procedure on both rear axles.
1. Lift the vehicle on a hoist.
2. Remove the rear wheels.
3. If needed, clean dirt and debris from the back side of the rear hub assemblies.
NOTE:
Rear axles will be pulled a few inches out of the hubs. Cleaning the back side of the hub assemblies will prevent dirt and debris for
entering the axle bearing area.
4. Remove the rear axle cotter pin.
NOTE:
If there is an adjusting cap over the lock nut - remove the adjusting cap.
5. Loosen / back-off the axle lock nut.
^ Do not remove the nut.
^ Back off the nut so it is flush with the end of the axle.

6. Tap / slide the axle a few inches inward, out of the hub.
^ Use a soft hammer, such as a dead-blow or brass type.
^ Using a soft hammer will help prevent damage to the axle threads.
7. On the back side of the hub, use a clean dry cloth to clean any existing grease, dirt, or foreign material from between the axle and bearing.
NOTE:
Completely removing the axle lock nut will allow the axle to slide further out of the hub and provide more working room between the axle
and the bearing.

8. Apply a minimum of 1.0g of Molykote M77 Grease in an even coating to the bearing surface where it contacts the rear axle (see Figures 5 and
6).
^ Use only Molykote M77 grease (P/N 44003-7S000). Do not use any other grease.
NOTE:
^ Figure 6 shows the hub removed.
^ This is done to provide a better view of the area where grease is to be applied.
^ It is not necessary to remove the hub for grease application.
9. Slide the axle back into place (outward).
NOTE:
Make sure there is NO GREASE on the threads of the axle or lock nut.

12. Install a new cotter pin.
13. Make sure to perform this procedure for both rear axles.
