No matter what type of vehicle you drive, power is transmitted through the drivetrain from the engine to the wheels. The drivetrain is made up of a transmission, driveshaft, axle, and differential. Gears and bearings within these components, however, won’t last forever, it’s likely some drivetrain repair work will be necessary at some point in time.
That's where we come from. The key is to minimize the need for drivetrain repair work by keeping the gears and bearings lubricated with the proper amount of clean oil or fluid. The cost of maintenance is a fraction of the cost to repair or replace one of these major components.
