$369.95 Differential and Haldex Fluid Service for VW Audi Porsche BMW
Changing the differential oil—it’s one of the most-overlooked maintenance tasks on cars. Because the differential is at the rear and under the car, it gets none of the star treatment that the engine up front does. However, if lubrication in the differential fails, you won’t be getting very far for very long. Fortunately, you only need to change this oil every 30,000 to 50,000 miles (as always, check your owner’s manual). Solution: Remove and replace old worn-out lubricant from manual transmissions, front and rear differentials, transaxles, and transfer cases. Install gear oil or the additive package required for vehicle application. You’ll experience smoother gear-shifting, quieter operation and extended component-life, which will reduce major repair costs due to worn gears.
