Xiaobian further learned that the use of this car is a taxi, the average owner of more than 100,000 kilometers a year! Now, Xiaobian can understand why the frequency of bearing replacement is so high, which is also a normal loss! Next, according to several pictures taken by the master, we will have a brief understanding of the process of changing bearings by the master! __________

As shown in the figure below, the master has removed the steering knuckle. The following figure shows the situation after removing the steering knuckle, the yellow area shows the steering tie rod ball head; the orange area shows the wheel speed sensor; the red area shows the half-axle outer ball cage; the green area shows the lower arm ball head; and the blue area shows the brake pliers assembly.

As shown by the arrow below, this is the ball head of the lower arm. The rubber sleeve has been damaged. It is said that such a ball head should be replaced, but the owners of taxis are reluctant, because there is no big noise, the owners will inject some lubricant into the ball head to continue to use.

As shown by the arrow below, this is the lower arm rubber sleeve. The owner also applies some lubricant to the edge of the slightly loose rubber sleeve, which can be used for a period of time.
