The vast majority of motorists sooner or later encounter such a phenomenon as noise and knocking in the suspension. The appearance of any extraneous sounds directly indicates that there is a problem in the car. If you can postpone some of the malfunctions, diagnose structural ailments as soon as possible. If you do not want to earn even more unnecessary problems on your neck. Not everyone knows, but a significant part of the diagnosis can be relatively easily done on your own.
1. Checking the ball joints
Ball joints are similar to steering tips. In order to diagnose the degree of wear of the supports, you need to lift the wheel on a jack by the lower arm. Or you need to drive the car into a hole and climb under it. Further, under the ball joint, the "assembly" sits down, after which we begin to swing it lightly. If there is any play, then the suspension is in trouble.
2. Checking the stabilizer struts
The stabilizer legs are checked in an extremely simple way. It is enough just to reach for them and take hold of them with your hand, and then twitch with force. If, in response to the pitching, a characteristic knock followed, then the problem was precisely in them - it was time to change the part.
3. Checking the thrust bearings
Pilot bearings are also not very difficult to check. It is enough to grasp the stock with your hand and gently rock the car from side to side. If a backlash is felt, then the bearing is not working properly and most likely it is he who is the source of noise in the suspension. It is best to replace the part as soon as possible.
4. Checking the racks
We sharply lean on the car and push, after which we also abruptly release. If the body, when returning to its original position, does not stop immediately, but begins to sway, then the car has problems with the struts. In addition, the racks should be inspected. If they are dry, then everything is fine. If the racks are wet, oil is already leaking from them. Even if the car isn't rocking yet, it's time to change.
5. Checking the steering tips
One more person is needed here. To check the tips, jack up the machine on one side and grasp the steering tip with your hand. Once this is done, the assistant should quickly shake the steering wheel left and right. If the person holding the handpiece feels impacts at this moment, then the part needs to be replaced.
6. Checking the wheel bearings
To check the wheel bearings, each wheel is understood on a jack and spins up. If a characteristic noise appears on one of the wheels at the moment of rotation, then a bearing has flown. If you spin such a wheel again and take hold of its rack, you can also feel the characteristic vibration.
