After a certain mileage, the car feels hot with the rear axle of the hand, indicating that the rear axle is overheated.

The reasons for the overheating of the rear axle are as follows:

(1) the bearings in the rear axle of the Mercedes Benz parts in Baotou are too tight.

The meshing gap between the main and the driven bevel gear of the Mercedes Benz parts in the north of Baotou is too small.

(3) lack of lubricating oil.

The lubricating oil is metamorphosed.

When overheating occurs, the quantity and quality of lubricating oil should be checked first. If there is not enough lubricating oil, it is necessary to check if there is any oil leakage part. If there is any oil, if it is repaired, then add lubricating oil. If lubricating oil is deteriorated, it should be replaced. Note that the oil should be removed when the oil is changed so as not to affect the new oil. If the above check is normal, the rear axle should be opened to check whether the bearing is too tight. Check whether the meshing clearance between the driving gear and driven gear of Baotou Benz accessory is too small, if the fault is detected, it should be excluded immediately.
