    I've got both drums off and both seals out. I getting ready to swap drums from one side to the other and I'm gonna press in new seals while I'm at it.

    Someone said to press them in about 1/16" shy of being flush with the drum, but it seems that the axle seal itself is what holds the outter bearing in place.

    Is this the way it's supposed to be? It almost looks like there should be a ring clip in there to hold the bearing in place??

    Thanks,

    Thomas.

    The seal doesn't hold the bearing in place. The bearing is held in place by a ridge on the spindle itself. The bearing just sorta flops around inside the hub until it's placed on the spindle.

    The spanner nuts and washer hold the bearing in place. The seal does nothing but hold the oil in. Well, not in your case, it seems, but the seal does not hold the bearing in. Just those round spanner nuts which you adjust.

    Hey, thanks guys [​IMG]

    When I took the old seal out, I removed the bearing and lined it up on the spindle and I see what you mean. So the seal doesn't hold any lateral force at all .......... I thought it did for some reason.

    Anyway, when I took the old seal out, the rubber (silicone?) was very hard and looked like it may have melted. Someone (sorry I don't remember who) said that the seals can burn up if you don't lube them up because it takes a while for the gear oil to get down the shaft.
    So this time, I greased up the Speedi Sleeve and the seal before I replaced the drum.

    I just got back from a 30-35 mile trip and it doesn't appear to be leaking. I probably won't know until morning though, as it seems to leak out over night.

    Thanks for the help,

    Thomas.
