Is it possible to replace the runner bearing that meets the CV axle at the front (driver side) differential in addition to the seal, or is a complete overhaul of the front differential required?

Good evening.

The seal is accessible from outside the differential, but the bearing is internal. The differential needs to be removed and disassembled.
