Rear differential service done by any Seattle Transmission Repair is scheduled maintenance item that involves draining and refilling the gear oil housed in the differential. The rear differential is responsible for transferring power to the ground on rear- and four-wheel-drive vehicles.
- The gear oil in the rear differential lubricates and prevents wear in the rear end gears.
- The rear differential is located in a centered position on the rear axle of a vehicle, between the two rear tires. The differential is identifiable because its housing is a large, bulging compartment you might be able to see from the rear of the vehicle. It has a check plug that is used to check and evacuate old fluid, and it may also have a drain plug to let old fluid out.
- In addition to transferring the engine’s power to the ground, the rear differential allows the rear wheels to spin at different speeds, as is necessary when cornering.
- When completing a rear differential service, be sure to use the oil recommended by your manufacturer. A dealership service department or your owner’s manual can point you in the right direction.
- Rear differential service can remove metal shavings and other contaminants that naturally enter the differential during normal operation. This prolongs the life of your differential and can ensure your vehicle remains covered by the factory warranty.
