1、塑料件之间的摩擦
1. Friction between plastic parts
这种异响与气温变化会有一定关系，气温降低后塑料会变硬，摩擦就会出现异响。除此之外，新车也会出现这种情况，方向盘由各种塑料件组成，方向盘在转动的时候如果相互间隙太小总会有摩擦，磨合上一段时间就好了。
This abnormal sound will have a certain relationship with the temperature change, the temperature will be reduced after the plastic will harden, friction will appear abnormal sound. In addition, the new car will also have this situation, the steering wheel is composed of a variety of plastic parts, the steering wheel in the rotation of the gap between too small there will always be friction, run-in for a period of time is good.
2、转向柱与脚垫之间的摩擦
2. Friction between steering column and foot pad.
这点是比较常见的了，如果汽车后安装的脚垫太大，与转向柱有着直接的接触，随着转向柱的转动就会产生摩擦，只要把脚垫位置调整一下或者更换脚垫即可。
This is more common, if the car installed after the footpad is too large, and steering column has a direct contact, with the steering column will produce friction, as long as the footpad position adjustment or replacement of the footpad can be.
3、方向盘内的气囊游丝故障
3. Trouble shooting of air bag in steering wheel.
拆过方向盘的车子更要注意了，可能是气囊游丝断裂或者气囊游丝插头没插，到店检查更换或者固定即可。
More attention should be paid to the car that has been dismantled the steering wheel. It may be that the air bag wiring is broken or the air bag wiring plug is not plugged in. Go to the shop and check for replacement or fixation.
4、转向横拉杆球头老化、有旷量
4, the steering rod's aging and the amount of clearance.
这个就需要更换转向横拉杆球头，而且在更换之后还需做四轮定位。
This requires the replacement of the steering tie rod ball, and it needs four rounds of positioning after the replacement.
5、方向机防尘套漏油
5. Leakage of steering wheel dust cover.
更换防尘套或者重新打黄油即可解决。重新打黄油是权宜之计。
You can solve the problem by changing the dust cover or re beating the butter. Butter is an expedient measure.
6、转向机故障
6, steering gear failure
如果打方向传来比较骇人的“咯噔咯噔”的异响，有可能是转向机配合齿轮间隙过大造成的，需要更换转向机。
If there is an appalling "chuck-chuck" abnormal sound coming from the direction, it may be caused by excessive clearance between the gears of the steering gear, and the steering gear needs to be replaced.
7、平面轴承/顶胶故障
7. Failure of plane bearing / top glue
在转动方向的时候传来“特特特”的响声，很有可能是减震器顶胶/平面轴承故障，需要更换。
The "Tete" sound coming in the direction of rotation is likely to be a rubber/plane bearing failure on the top of the shock absorber and needs to be replaced.
8、助力皮带松紧度不当或老化
8. Improper or aging of the belt's tightness.
对于机械液压助力，如果助力皮带松紧不当或者老化，就会传来异响声，调整皮带松紧度或者更换皮带。
For mechanical hydraulic power, if the belt is not tightened properly or aging, there will be abnormal sound, adjust the belt tightness or change the belt.
9、转向助力油太脏
9, steering power is too dirty.
如果助力油太脏会增加助力系统的压力，助力泵就会传来“嗡嗡嗡”的异响声，因此要及时更换转向助力油。
If the booster oil is too dirty will increase the pressure of the booster system, booster pump will come out of the "buzz" abnormal sound, so to replace the steering booster oil in time.
