Approaching 15K miles on the Passport and the Maintenance Minder is showing "B16". The "6" is for a "Rear Differential Fluid Change" at 15K mile intervals or 7.5K mile interval for severe conditions. Have not actually performed the fluid change, yet. Based on information found, this is the procedure. Honda service charges $100 to $150?
Prep for a DIY rear differential fluid change, will need:
Fluid fill bolt is at the rear of the differential behind the rear axle frame. Undo the fill bolt first with socket extension and 3/8" ratchet or breaker bar, in the event that there is trouble with the drain bolt. Photo is looking forward from the rear of the vehicle...
Fluid drain bolt is on the left side, towards the front of the differential. With oil pan beneath, undo the fill bolt first with 3/8" ratchet or breaker bar. Photo is looking forward from the left side, behind the left rear wheel...
Clean drain bolt and replace the washer. Reinstall drain bolt and torque to 35 ft-lb.
Refill differential with new fluid using pump until it starts to overflow. Per the owner's manual, it is just shy of 2 quarts.
Clean fill bolt and replace the washer. Reinstall fill bolt and torque to 35 ft-lb.
Done.
