Small cars and compact cars are the most common types of vehicles that use rack and pinion steering systems. These vehicles are usually used for urban commuting and are designed to provide smooth handling and low manufacturing costs. ·Representative models: Honda Civic, Toyota Corolla, Volkswagen Golf, etc.

If the driver is used to more intense driving, he may tend to choose a design with more sensitive steering. At this time, it is more appropriate to choose a gear with more teeth. For vehicles driven in daily cities, drivers may prefer easier and more comfortable steering. Appropriately reducing the number of teeth may bring a better driving experience.

The design of the electric steering rack is based on a certain intensity of use and load conditions. If the vehicle is overloaded for a long time, or during long-term high-speed driving, frequent parking and steering, the electric steering system may encounter excessive load.

The hydraulic oil should be kept in the pipes and steering rack inside the system, and should not flow out through the dust cover. If there is liquid outflow or accumulation in the dust cover, it usually means that there is a problem with the steering system, which may involve aging, damage or oil seal failure of the seal.

In other words, after the car is turned off, although the hydraulic system no longer maintains pressure, the hydraulic fluid in the system may continue to leak due to gravity or residual oil pressure. In particular, power steering fluid is more likely to leak in the following situations: 1. There is a small leak in the system 2. Leakage caused by pressure release 3. The influence of parking posture:

The steering system offset of old cars is more obvious, that is, when the steering wheel is slightly turned, the wheel does not turn quickly. This offset will make the driver feel that the control is not precise enough when driving at low speed or turning.
