Differential and Transfer Case (4WD) Service 4x4

Differentials

The differential transfers the engine power to the wheels. One important function of the differential is to pass on power to the wheels while allowing them to rotate at different speeds - thus the name differential. When turning, the outer wheels travel a larger distance than the inner wheels do (also the front wheels travel a longer distance than the rear wheels). This means that all four wheels travel at different speeds during a turn and this is where the differential comes in to help. To make sure your vehicle's differentials are working properly, have them checked regularly. On occasion we will inspect and find fluid leaking from a seal within the differential without repairing the leak by replacing a seal could lead to a major repair of replacing the differential all together.  Keeping the differential leak free and fluid clean will help your vehicle stay problem free much longer.  Contact Fairfax Auto Repair today for differentials examination and servicing.

Differential Flush

The differential is a car part that compensates for the difference in travel distance between the inner wheels and outer wheels when the vehicle is turning. Due to the differential's position in most non-four-wheel-drive (FWD) vehicles (located at the rear and under the car), it does not get any of the star treatment the engine gets. The one thing that every car owner needs to know is that failure of the differential will mean failure of the car. To save the differential from failure, you need to have differential fluid changed every 30,000 to 50,000 miles. Changing the oil on the differential is as important as changing the car's engine oil. Although checking and changing differential oil is pretty easy, you need to visit an auto shop to get a comprehensive differential flush.
