Quick 110 rear stub axle question

[gm13]

What keeps the oil in and water out of the early model(up to '89 apparently) 110 rear axle?
The stub axle has no oil seal for the axle passage as it does on the fronts. My 110 has oil leaking out of one side, from under the dust cap right along the axle splines, but not the other. What gives?

Nothing really. Maybe time to replace the stub axle?

This is normal. The rear bearing are wet. The cap needs to be replaced is all that is required to fix your leak. Use quality wheel seals and grease pack your bearings. Oil takes a while to migrate to the bearings from the diff.

I assume that is why the design changed. Well it has new bearings and seal anyway, stub axle appears to be a recent re-fit, looked good as did the bearings, oh well.
Thanks for the input.

The change to dry hubs was a backwards step - the oil migration through the unsealed stub axles allowed lubrication of the splines and also ensured the wheel bearings couyld never run dry. A smear of RTV sealant when fitting the plastic cone to the drive flange keeps it all clean and sealed.

Later axles with stub seals go through drive flanges and half shafts much faster because of the dry splines, and wheel bearings seem not to last as long despite greasing as the grease appears to gradually dry out unless "refreshed" by oil from the diff area. This is why the removal or deliberate cutting of stub seals on later axles is so common (the hub caps are more prone to leaking than the early type if this is done, so make sure you use sealant on them).
