BX23S Front Axle Oil Change

This is a hands-on, step-by-step walkthrough of draining and refilling the BX23S front axle/diff fluid, done early at roughly 275 hours ahead of the 400-hour service interval. It covers tools needed (14mm socket, screwdriver, drain pans), fluid choice (Super UDT vs. 80-90 gear oil), the 3.8 quart fill amount, using compressed air to speed draining, and checking level after a 10-minute settling period. Best for owners doing this service themselves.
