What Causes the Clicking Sound When Turning the Steering Wheel After Replacing the Shock Absorber?

After replacing the shock absorber, the steering wheel may produce abnormal sounds for the following reasons: 1. Damaged turn signal return spring causing noise: If the sound occurs only after activating the turn signal and then turning the steering wheel, it is the sound from the return spring of the turn signal auto-return mechanism. This sound is normal and is designed for the convenience of the driver. 2. Noise from the steering column dust cover: Whether stationary or driving, if you hear a sound coming from below the steering wheel when turning it, you should check the steering column dust cover. Lack of lubrication in the dust cover can cause dry friction sounds. Applying some grease inside the dust cover will eliminate this noise.

Damaged steering damper: Oil leakage or deformed front suspension springs also affect stability. 3. Loose wheel hub bearings or severely worn steering knuckle ball joints: Result in inaccurate front wheel alignment. 4. Loose lateral thrust rod ball joint or bracket: Causes unstable driving. 5.

What is the unit of measurement for car speed?

There are two units of measurement for car speed: km/h and mph. In China, the unit used is km/h. 1mph equals 1.609344km/h, and 1km/h equals 0.6213712mph. The commonly mentioned horsepower is not a unit of car speed. More details about car speed are as follows: 1. Introduction: Japanese, Korean, and German cars typically use kilometers per hour (km/h) to indicate speed, while American cars generally use miles per hour (mph). The unit used depends on the country. Many car owners habitually refer to km/h as "miles," but this is not the standard speed unit in China. "Miles" actually refers to mph. 2. Horsepower: Horsepower is an important parameter of an engine, representing the work done by the engine per unit of time. For cars of the same mass, the greater the engine's power, the higher the car's speed. 3. Car speed regulations: Motor vehicles must not exceed the speed limit indicated by road signs. On roads without a central dividing line, the speed limit is 30km/h in urban areas and 40km/h on highways. On roads with only one lane in the same direction, the speed limit is 50km/h in urban areas and 70km/h on highways. When turning, the maximum speed of a motor vehicle must not exceed 30km/h.
