5-Screw Automatic Hub Lock Exploded
IF THE IMAGE IS TOO SMALL, click it.
3B459 - E5TZ1198A
There should never be a need to disassemble the hub lock body to this degree, unless it has been severely neglected or abused. DO NOT pack the lock with grease - a light coat is enough; any more will jam the mechanism. The correct way to clean & lube an auto hub lock is to dunk it in ATF each time the wheel bearings are serviced (which should be FREQUENTLY if the truck is used off-road; or every 30Kmi if it's not).
The inner & outer wheel bearing adjusting nuts are not shown, but the outer (without pin) goes outboard of the perforated locking washer (3B459), which goes against the inner (with pin pointing out). If the pin is pushed into the nut, use a drift to push it back out.
