Had the same problem with a 86 Ford 1 ton. Wound up upgrading seals. went with a Scott seal. The outside diameter of the seal is stationary to the wheel hub and the inside diameter of the seal is stationary to the axle housing. The seal surface is inside the seal itself.

A rotating type seal is a more robust design especially for axle hub or axle shaft service. They are substantially more expensive along with being a bit harder to install successfully. This is the type seal found on most late model class 6/class 8 trucks and final drive shafts on crawlers due to their ability to survive in harsh conditions.

Would this be called a UNITIZED seal? When searching around I found a seal at a place called Quad4x4.com has a Unitized Seal part# QU50247 that sounds just like this design. They are $30/each so that fits the 3X price that was mentioned.

QU50247 is a unitized oil bath rear wheel seal that is designed so the inner sleeve rotates within the outer Seal Shell. This means the seal is a press fit on both the spindle and in the wheel hub.

I’m certainly going to chase down the vent to make sure it’s free and will also ensure fill level and spindle nut preload. Assuming all of that is fine and these seals just failed, then it sounds like a unitized seal is the way to go to avoid future problems.
