5-screw Lock Disassembled
This level of disassembly is NOT necessary for removal or replacement.
4-slot spanner nut - E5TZ1197A
4-tab lock washer - E5TZ1198A
This early axle uses a single thick steel splined thrust washer (closest to the cap screws) instead of the later 3-piece thrust washer. Install three washers in order: metal washer first, plastic washer second and splined washer last.
