[Blue Bowtie]

There is such a thing as an "axle saver" bearing assembly for a 10-bolt, and those use a sealed bearing to replace the original open bearing. The philosophy is that the bearing inner seal will keep the axle oil in the housing, and the prepacked bearing will last as long as a modern design cartridge/hub bearing type. As we all know, that is not "permanent.

As such, they unfortunately tend not to last as long as the original design and are therefore a fairly temporary repair as a result. That "temporary" could be another 100K miles, but may also be less.
