Charlie's Auto Tech

The bumper to bumper car doctor of choice.

Your vehicle's differential is where the rotation of the drive shaft (powered by your engine) is communicated to your car's axles (where the wheels are attached). That's a perpendicular change, so it requires a special set of gears, protected by a box full of fluid. 4-wheel drive vehicles have 2 differentials: 1 in the front and 1 in the back. Your car's differential is essential, so make sure you keep it properly serviced!
