And the knock in the front suspension, if you heard it in time and determined the source of the knock - will prevent your car from a serious breakage. The knock in the front suspension can not only report problems in the suspension system and depreciation, but the knock may be as a result of the production of the steering system, the problem in the brake system and the engine. To determine the source of the knock, it is necessary to make a comprehensive diagnosis.

Suspension system and depreciation, why a knock in the nodes of these systems occurs

To determine the fault in the suspension and depreciation system, you must have a viewing pit or a lift, as it is necessary to look under the car and inspect the following nodes carefully:

-The check whether silent blocks in the car suspension levers work.

You can check it yourself, it will take a flat mount for this. By moving the mount, both in the longitudinal and transverse direction, you can reveal the backlash and wear of the rubber sleeve - it may be the cause of the knock;

-Next step - check the work of the ball supports.

To check, you need to raise one side of the car, using a jack.

Holding two hands per wheel, take it right to the right, to the left at this time, follow the behavior of the ball support.

If there are doubts, take the mount, install the support for the mount and if you feel the play of the ball support while moving the mount - it is required to replace it;

- Check the rack shock absorbersSince due to a defect one of the racks, a deaf knock in the front suspension is possible.

For this it is necessary, in turn, shake the front of the car, from the same side.

A knock at swing talks about the problem of the shock absorber struts;

- Check the status of the hub bearing.

It is necessary using a jack to raise the front part of the car, take up the bottom and top of the car's wheel and try to shift it in the vertical plane, if there is wear bearing, you will feel it;

- Check the condition of the steering of the car, how to do it, is described in the next chapter.

Car steering, possible reasons for knocking

The reasons for the knock in the front of the car are possible due to problems (wear) of individual parts of the steering system.

Steering thrust have hinged connections and tips, wear out, gaps appear in the rod, when driving around the uneven road, knocking knocks and noises.

To check the quality of steering tips, use the overpass or observation pit.

To work, a partner is needed, it must turn the steering wheel sharply, and you put your palm on the tip if there is a gap - the knock is transmitted to the hand.

Grasp the tip and pull it up, down - when defect you hear a knock.

To check the status of the steering, take the hand for the thrust and you can feel the defect in the hinge connection.

Brake system, reasons for knocking

Disorder in the brake system, very often the cause of the knock in the front suspension.

The knock may appear when the brake disc defect, the brake shoe defect.

If, when you click on the brake pedal, the knock disappears, and after the pedal is released, it appears again - the problem in the brake pads.

To clarify the reason, lift the car and remove the wheel. Remove the outward brake disc with a stupid and caliper and you will see visually, which is going on with brake pads.

Very often, the brake pads from an unknown manufacturer become problematic immediately after installation.

Therefore, refrain from buying cheap brake pads - life, more expensive.

To identify all the front suspension knocks, you spend a lot of time, but thereby you will learn your car, you will find a worn item and may be able to replace it with your own hands.
Good luck to you and calm, silent trip.
