10,000 kilometers should be changed once the rear axle oil;

Gear oil should be changed every 60,000 km;

Nowadays, there are two main types of gear oil, one is synthetic oil and the other is mineral oil.

If the synthetic oil used has a very long life, it does not need to be replaced within 200,000 kilometers, while mineral oil is different, mineral oil needs 2-3 years or 4-60,000 kilometers to replace.

Different types of gearboxes and transaxles use different viscosity designations, with a viscosity of 75W-90 for small passenger cars and 80W-90 for large trucks and transaxles.

It is replaced once every 4-60,000 kilometers.

If the vehicle gears smoothly and the transmission noise does not change much, the user can consider not changing. If the vehicle looks jerky when changing gears, especially if the transmission noise increases significantly after driving at speeds above 100 km/h, the user should consider whether it is time to change the transmission oil. Of course, there are also some vehicles that have had their gearboxes repaired, and such cars strongly require the first warranty at 3,000 kilometers, and then change the transmission oil every year or 20,000 kilometers.

Wuling Hongguang rear axle oil and gear oil are the same. The rear axle of a car refers to the bridge behind the car. If the front axle is driven by a vehicle, then the rear axle is only a follower axle and only plays the role of load.

It is usually equipped with a transfer case in front of the rear axle. The working principle of the rear axle of the car is as follows:

1. The engine transmits power to the gearbox, and through the transmission to the rear axle large chainring (differential);

2. The differential is a whole, and it is: there are small chainrings up and down, and there are ten pillars in the middle with two asteroid gears (playing the role of turning speed regulation);

3. The differential is placed in a vertical position, there are two small round holes on both sides, there are sliders on it, the ten pillars do not move when walking in a straight line, and the ten pillars move to adjust the speed of the tires on both sides when turning, so as to improve the mobility of the car when turning.
