Dangerous for the cracking control arm

The lower control arm of the car will play the role of bearing the load. If the bushing of the lower control arm cracks after being used for a period of time, there is a certain danger. We need to replace it with a new bushing, otherwise it will affect the driving of the car. Stability and maneuverability during the process.

Why is the lower control arm bushing damaged?

1. Whether the bushing of the lower control arm of the car is damaged, we can directly observe it with the naked eye. If there is a crack, it means that there is a problem. At this time, we need to replace it. If it is completely disconnected, then the problem is even worse.

2. And we can also analyze whether the bushing of the lower control arm is damaged through the experience in the process of driving. If we obviously feel the abnormal noise or looseness of the chassis, it means that the lower control arm needs to be replaced.

After the bushing of the lower control arm of the car has a problem, we must replace it in time. If we don’t change it all the time, it will affect our use and there is a certain safety hazard.

The effect of aging of the bushing of the lower control arm:

1. The bushing of the lower control arm is broken, and the tire will swing abnormally when driving. When checking, it is necessary to see whether the play of the ball head of the lower control arm in the ball joint increases;

2. The bushing behind the lower control arm is damaged, and the bushing with cracks will cause abnormal noise when the vehicle is driving on uneven roads;

3. The lower control arm of the car is the guide and support of the suspension, and its deformation affects the wheel alignment and reduces the driving stability. If the front control arm is damaged, the steering wheel will shake, and it is easy to go off track after the hands are released from the steering wheel.

If the bushing is aging and completely broken, it must be replaced. The lower control arm is an important part connecting the front axle and the tire. Once the tire angle changes, other connecting parts will be easily damaged.

After the bushing of the lower control arm is damaged, the control arm is in hard contact with the shaft, and the metal directly hits the metal, resulting in a huge rattling sound. On the other hand, the gap between the control arm and the shaft becomes too large, resulting in failure of the wheel alignment parameters, which may lead to wheel eccentric wear, tire eating and other failures

Lower control arm bushing replacement price:

The price of the bushing of the lower control arm of the car is about 300 to 500 yuan. After the damage occurs, the bushing can be replaced separately. Although the price of replacing the bushing is not expensive, the replacement requires a very troublesome process, and the car needs to be lifted first. Use a special tool or an automotive hydraulic press to push out the lower control arm bushing before replacing it with a new one.

The entire replacement process is very complicated, so although the price of the bushing is not expensive, the replacement needs to pay a certain amount of labor costs, etc., and the price is also very expensive.
