SOLID SPACER INSTALLATION INSTRUCTIONS:

                             1. Measure the used Crush Sleeve that was originally in the housing. (if not available start with 3 shims)

                             2. Add enough Shims to the spacer to achieve a total length that is slightly longer than the used Crush Sleeve.

                             3. Install Spacer and torque the Pinion Nut to 125 foot pounds.  At this point pinion pre-load should be loose.

                             4. Remove the Spacer and Shims. Reduce this Shim Pack in .002 thickness increments and install until the proper bearing pre-load is achieved.
