Rear axle seal, 1930

[Kurt in NJ]

The seal in the hub(drum) can be changed without removing the rear end, the internal axle seal needs the rear out and dissambled

The internal seals on my car havn't been any good since before I owned the car(1969), my trans leaks into the rear, it has to be drained ---but the seals in the drum/hub have been holding back the oil even when it is overfilled.

there was a aftermarket seal that fits into the end of the axle housing ---I don't know if it is reproed, I just drain the rear out the fill plug and fill the trans every year--perhaps I don't have problems because I have old type leather seals in my hubs

inside the backing plate there is a grease baffle, that leads to a hole in the bacxking plate with the intention of directing seal leakage outside the backing plate through a hole----when I put mine together I sealed the plate to the backing plate to ensure leakage goes out.

the oil level in the rear should be below the hub/axle level, the hub seal should be able to prevent leakage even if the internal seal is bad---the rear wheel bearing can get lubed with gear oil
