Corvette Technical Service Bulletin 599 Rear Spindle Change
Year: 1963-1963
Download: Supporting Documentation
Excessive rear wheel spindle and spindle bearing wear on 1963 Corvettes may be a result of the bearing inner races rotating on the spindle.

Design improvements to the spindle and spindle flange assemblies have produced two interim production changes to eliminate this wear problem. A review of spindle design is outlined on page 2.

These design changes have also resulted in revised service procedures and a deletion of the 30,000 mile
service interval. The new spindle assembly requires no periodic servicing.

Where complaints of spindle wear are encountered on vehicles built before December 3, 1962, the problem may be corrected by replacing the original design or interim change spindle and flange with the new part No. 3840378 spindle , part NO. 3839830 drive flange and Part NO. 3839832 flange washer. Service instructions on the following pages outline the recommended service procedures and tools.
