The owners who are accustomed to seeing the fault from various indicators，Do you know again，Small steering wheel，Can many failures be judged? today，Let's talk about the steering wheel with a large role in small bodies，What can I judge?

When the vehicle is driving，There is a periodic sound of the chassis，In severe cases, the cab and the door shake，The steering wheel is strong vibration，until the hand is numb。This means that the car fails!

Shake and numb at idling

Steering wheel shaking is not common when idling，Of course, the amplitude of this jitter is not very large，Generally because of resonance，It has little effect on the use of vehicles，You need to check whether there is a problem with the glue cover of the steering wheel transmission device、Whether the bolt of the transmission device of the fixed steering wheel is loose。

The speed of the car appears at 30 to 40 kilometers per hour

This situation appears most because the tires are rubbed due to daily use、Bullet or old cause caused by deformation，Just change the tire at this time。

The speed of the car appears at 80 to 90 kilometers per hour

This situation occurs mostly due to tire deformation or vehicle transmission system。At this time，Should check whether the front wheels and bouquets meet the requirements，If you are in trouble, adjust it，or stand up the front bridge test and rotate the wheel，Check the balance of wheel static and whether the tire is too large，If the deformation is too large, replace it。

Step on the brake shake at high speed

Excessive seabet iobrake force、Excessive frequency may lead to the brake disc、The brake pads are overheated，Cold deformation，Causes the steering wheel shake。Generally changing the brake disc、After the brake pad，Symptoms can be solved。

Platform roads are normal, low -lying road sectionsAbnormal

This is due to the car when the car is driving，Polying from the rod ball to wear a looseness or the glue set at the joint，It may also be irregular due to wear，Checking professional maintenance points for professional maintenance，Replace the damaged parts。

If you find that the car is just started，The first steering wheel is particularly heavy，Then just fight again，Generally because the driver is in the direction，There is a valve in the direction machine to open，Makes oil circulation。

As soon as the valve is stuck, there will be a steering wheel sinking situation。But if you always turn to labor，Generally there may be several cases:

Insufficient tire pressure

In particular, pay attention to the front tire pressure，If there is tire pressure monitoring in the car，It is easier to find problems。

Steering system

Steering rolling bearings and sliding bearings in various parts of the steering system are too tight，Bearing lubrication bad，Turn to the longitudinal pull rod、The ball head of the horizontal pull rod is too tight or lack of oil，turning shaft and sleeve bending，Card stagnation。

Improper coordination

Improper adjustment of the front wheels, the front sedan or frame bent.

The cause of the running bias is large and small，But basically caused by left and right asymmetric。

left and right tire pressure asymmetry

The simple and easy -to -handment situation isLeft and right tire pressure asymmetry,Which side of the tire pressure car is easy to partially biased。In short,，Check the fetal pressure first if you have any questions，The tire pressure is not wrong and then deepen。

seabet loginSuspension components aging wear

Severe more may be the aging wear of the suspension parts，Cause caused by different gaps，This situation generally occurs in an old car for more than 8 years，It can be completely solved by replacing parts。

Step on the brakes to run off

If you are not running when you drive normally，Drive when stepping on the brake，The more heavier you step on, the more severe the more severe。This may be caused by the brake system's braking power imbalance of the left and right wheels，It is best to monitor the braking system。

steering wheel crooked

The steering wheel is crooked because the positioning parameters are chaotic，Just to offset，The burden at this time is all borne by the wheels。

First, see if you step on the brakes,Followed by the steering wheel after the switch is turned into the switch, there will be this sound，If it is not the above situation，So you need to judge the direction of the sound。

The sound came from under the steering wheel

Check the direction column dust -proof set，Once the direction of the pillar anti -dust cover lacks lubrication, it will produce friction，You only need to paint the sound of butter in the dustproof cover and it will disappear。

The sound comes from the steering wheel

Most of this problem is caused by the interference of airbags in the steering wheel，Remove the steering wheel airbagwater to paint some butter and see it.，If you are still ringing, you can change the airbags，It may be damaged by airbags。

Pay attention to checking the help system and steering machine

1、Check if there is an oil seepage in the help tank，Is there any oil exudation at the pipeline joint。

2. Determine whether it is short of oil in the oil tank after the non -oil seepage.

3. Check whether the hydraulic oil has become dirty and deteriorated.

4. Check whether the pump is damaged.

1、The internal gear of the steering machine is severely worn seabet loginout，Can't cooperate well，Frication and collision during steering causes abnormal noise。

2. Electronic assistance servo motor fails and needs to be replaced.

3、The sealing ring of the bearing of the internal bearing of the steering machine is aging or damaged。

4、Help the motor card，Hold the steering wheel with your hands，The abnormal noise will disappear。
