Have a 4X4 or all-wheel drive vehicle? You may have a transfer case. Regular fluid replacement will keep you on- and off-roading.

What is a transfer case? This unit controls the flow of power to the front and rear drive axles when you shift back and forth between two-wheel and four-wheel drive.

Why replace the fluid? You’ll help extend the life of your transfer case by effectively reducing the wear and tear on the gears and parts inside.

*Many auto manufacturers recommend replacing transfer case fluids at regularly scheduled intervals. Check your owner’s manual for details.
