The transfer case is a mechanical component in all four-wheel-drive and all-wheel-drive vehicles. It distributes engine power from the transmission to the front and rear driveshafts, acting as a differential between the front and rear wheels. The transfer case can be controlled manually or electronically and allows for gear reduction at low or high speeds.
Every transfer case requires fluid to lubricate the ball bearings, gears, and chains. Depending on the application and the manufacturer’s specifications, the lubricant can be oil of a specific viscosity or automatic transmission fluid. Your certified NAPA AUTOPRO technician knows the right lubricant to use for each vehicle and how often it should be replaced.
With time and kilometers, the lubricant becomes contaminated, additives lose their properties, and tiny suspended particles can cause premature wear. That’s why it’s important to change the transfer case fluid regularly. When needed, your certified NAPA AUTOPRO Service Centre South Surrey technician can replace the fluid for you during routine maintenance.
