This is a real-time, hands-on front axle oil change on a Bad Boy 4025H at the 50-hour service mark, not a talking-head overview. The owner drains both sides with 17mm and 27mm plugs, measures out roughly a gallon and a half to a gallon and three-quarters of old fluid, refills with Valvoline 80W90, troubleshoots slow flow through the breather, and checks the dipstick. Best for owners doing this exact service themselves.
Appears to be an owner-operator documenting their own DIY maintenance, working through the process (including mistakes) in real time rather than presenting polished expertise.
