The rear differential controls the rear pair of wheels so they can spin at different speeds, allowing your car to move smoothly and maintain traction. If you have a rear wheel drive car, you have a rear differential. Front wheel drive vehicles have a differential located at the front of the vehicle. The rear differential is located at the rear of the vehicle under the vehicle. On these types of vehicles, the drive shaft interacts with the differential through a crown wheel and a pinion that is mounted on the carrier of the planetary chain that forms the differential. This gear helps change the direction of rotation of the drive, and the gasket seals the oil.

The rear differential gasket requires lubrication to keep the part running smoothly. Lubrication comes from differential/gear oil. Every time you change or change the fluid, the rear differential gasket also changes to ensure it seals properly. The differential oil should be changed approximately every 30,000-50,000 miles, unless otherwise noted in the owner's manual.

Over time, the gasket can be damaged if the gasket breaks and oil leaks out. If this happens, the differential may be damaged and the vehicle will become inoperable until the differential is repaired. If you service and lubricate the rear differential gasket, there is less chance of your differential being damaged. However, if you suspect a gasket problem, a professional mechanic can diagnose and replace the rear differential gasket in your vehicle.

Because the rear differential gasket can break or leak over time, it's important to know the symptoms to keep up with maintenance. So it's more of a simple repair than an extensive one like replacing the entire differential.

Signs that the rear differential gasket needs to be replaced include:

• Fluid leaking from under the rear differential that looks like engine oil but smells different
• Rattling noise when cornering due to low fluid level
• Vibrations while driving due to fluid leakage

Make sure the rear differential gasket is properly serviced to keep the vehicle in good running condition.
