I found this on the G:

". I inspected the nut assy. more closely and did discover the axle nut and seal are two parts that can be separated and the seal portion replaced. I have quite a generous stash of the seal portion that is neoprene."
Anyone know what he's talking about? My nut is shot (one to many screwdriver blows to the castellated nut) so I have found NOS replacements. I bet they will be spendy.
But, for future reference.. anyone have any idea how to replaces the seal only portion????? Would be a good tip to share.
