1、塑料件之間的摩擦
1. Friction between plastic parts
這種異響與氣溫變化會有一定關系，氣溫降低后塑料會變硬，摩擦就會出現異響。除此之外，新車也會出現這種情況，方向盤由各種塑料件組成，方向盤在轉動的時候如果相互間隙太小總會有摩擦，磨合上一段時間就好了。
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、轉向柱與腳墊之間的摩擦
2. Friction between steering column and foot pad.
這點是比較常見的了，如果汽車后安裝的腳墊太大，與轉向柱有著直接的接觸，隨著轉向柱的轉動就會產生摩擦，只要把腳墊位置調整一下或者更換腳墊即可。
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、方向盤內的氣囊游絲故障
3. Trouble shooting of air bag in steering wheel.
拆過方向盤的車子更要注意了，可能是氣囊游絲斷裂或者氣囊游絲插頭沒插，到店檢查更換或者固定即可。
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、轉向橫拉桿球頭老化、有曠量
4, the steering rod's aging and the amount of clearance.
這個就需要更換轉向橫拉桿球頭，而且在更換之后還需做四輪定位。
This requires the replacement of the steering tie rod ball, and it needs four rounds of positioning after the replacement.
5、方向機防塵套漏油
5. Leakage of steering wheel dust cover.
更換防塵套或者重新打黃油即可解決。重新打黃油是權宜之計。
You can solve the problem by changing the dust cover or re beating the butter. Butter is an expedient measure.
6、轉向機故障
6, steering gear failure
如果打方向傳來比較駭人的“咯噔咯噔”的異響，有可能是轉向機配合齒輪間隙過大造成的，需要更換轉向機。
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、平面軸承/頂膠故障
7. Failure of plane bearing / top glue
在轉動方向的時候傳來“特特特”的響聲，很有可能是減震器頂膠/平面軸承故障，需要更換。
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、助力皮帶松緊度不當或老化
8. Improper or aging of the belt's tightness.
對于機械液壓助力，如果助力皮帶松緊不當或者老化，就會傳來異響聲，調整皮帶松緊度或者更換皮帶。
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、轉向助力油太臟
9, steering power is too dirty.
如果助力油太臟會增加助力系統的壓力，助力泵就會傳來“嗡嗡嗡”的異響聲，因此要及時更換轉向助力油。
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.
