Each four-wheel drive system has three main parts: the front and rear differentials, and the transfer case. At EconoLube, we provide specialized service to keep all of these components running smoothly.
The differential is a gearbox that makes it possible for you to turn your vehicle. Four-wheel drive vehicles and all-wheel drive vehicles have the differential between the front and rear wheels, whereas a rear-wheel drive vehicle has a differential on the rear wheels only, and a front-wheel drive vehicle does not have a differential. The differential enables the wheels to turn at different speeds by employing a series of gears. This control of the wheel speeds allows the vehicle to turn corners with better traction.
As the gears grind together, a great amount of friction is generated, and over time these continuously high temperatures during operation cause the lubricating fluid in the differential to deteriorate, and the fluid’s ability to protect the gears from wear decreases. Therefore, the differential fluid must be replaced regularly to avoid costly repairs to the gear system.
Our EconoLube technician can remove the old differential fluid from the differential and replace it with new high-quality fluid that contains the proper additives to help protect the seals, gears and bearings and ensure they operate at optimum potential.
EconoLube recommends servicing your vehicle’s differential according to manufacturer’s recommendations. If the differential fluid was contaminated by water or some other severe circumstance occurred, the differential fluid should be changed sooner to prevent damage to the vehicle.
Transfer case services
The transfer case is attached to the transmission and is responsible for delivering power to the rear differential and also to the front differential when required. In the case of an all-wheel vehicle, the transfer case maintains power to both the front and rear differentials at all times.
The lubricating fluid in the transfer case deteriorates over time, giving way for heat, friction and pressure to cause premature wear to the transfer case which could result in failure and costly repair. Let our EconoLube technician service your vehicle’s transfer case by removing the old lubricating fluid and adding new fluid according to the owner’s manual guidelines.
