"Inside-out" seal

O-Rings don't like sealing on rotating surfaces such as hubs, but will tolerate sliding surfaces (as in a Piston Ring).

Perhaps a Speedi-Sleeve could be used to dress the surface to be suitable for a regular seal? Unfortunately, it might need to be removed and replaced each time the bearing is replaced, but how often do you expect that to be?

Is this on the spring mount for the trunnions (the spring mounts) as would be on a 6 wheel drive truck? If so I understand your dilemma of the assembly order. The later US military trucks are a similar setup but larger seals.
