Checking the oil differential gear of the car
The differential gear inside your car allows the drive wheels turn at the right speed when you step on the accelerator pedal at different speeds when turning a corner. The gears are coated with a layer of oil that protects the hardened layer on the teeth due to wear by friction. Periodically, the differential gear oil should be reviewed to ensure it is sufficient to protect the difference, in this article we’ll do it.
1. Park your car on a flat surface. The car must be kept level to get a true reading of the difference in the gear oil level. If the car is not level, the oil can flow to one side of the reservoir.
2. Place the car on jack stands. Raise the car on the front and rear support jacks to keep up.
3. Find the differential. The differential pumpkin-shaped and is in the wheels of the car. If the car has front-wheel drive, the difference will probably be in the front, if the car has rear-wheel drive, the difference will probably be in the back.
4. Locate the drain bolt differential. The bolt is usually located next to the differential in front of the rear of the car, although it may be located at the top of the differential.
5. Remove the drain bolt with a wrench. Wait until the gear oil leaking completely. But you can put your finger in the drain hole to check how far your finger is stained with oil. If you enter a lot, probably have to add oil.
6. If necessary, add oil to the differential gear. Oil for the differential gear can be purchased at most auto parts stores in bottles to add it to the sump pumps. Be sure to use the weight rating and GL differential gear oil required by the manufacturer of your car.
If your car has a limited slip differential, which can detect if a wheel is on a slippery surface, the differential gear oil must contain special lubricants for the differential can do its job properly. Since different car manufacturers use different mechanisms, each requiring its own lubricants. You must use the oil change requested by the manufacturer if you have a limited slip differential.
7. Replace and tighten the drain bolt. Clean any excess oil from the differential gear box and check to make sure the liquid does not leave after tightening the screw.
8. Carefully lower the vehicle back to earth. Check again for leaks gear oil.
