Symptoms: When you cross a hurdle, the front of the car will shake and make a squeaking sound

Inspection showed that the rubber at the ball head was cracked and the oil leaked, as shown in the picture

These are the old parts that have been removed. The screw mouth of the original balance bar is a hexagonal star, and the new part is a hexagonal or pentagonal one.
The ball head on the front right is rotten to death. The left front is fine, but there are also cracks.

Look for the mark on the new piece, L is left front, R is right front.

There are screw caps, but the technician said that the original screw caps are better and use the original factory.

After changing it and driving it, I feel that the front of the car is stiff and much more stable!
The current mileage is 97,000 kilometers. I suggest you also change it early. The two balance bars are 300 yuan and the working hours are 80 yuan, making a total of 380 yuan.
