Manual Hub Locks
IF THE IMAGE IS TOO SMALL, click it.
These use 3 washers (15,16,17) between the C-clip & the spindle to hold the axle stub in place. The previous design used a single thick splined shim. Before that, an outside snap-ring was used at the outer end of the axle stub. In both cases, before the small outboard snap ring (18 in this diagram) can be installed, the stub shaft must be pushed fully outboard against the inner spindle seal by reaching behind the steering knuckle to the u-joint.
Regarding part #2: I think the double-lip faces INboard (toward the diff) so that if pressure is higher OUTside the hub (deep water), the double-lip will expand slightly, forming a tighter seal against the axleshaft & spindle bearing race. But that's just a guess.
