What is the phenomenon of heavy steering in a car?
2 Answers
The phenomenon of heavy steering in a car is as follows: 1. Insufficient tire pressure, especially in the front tires. 2. Insufficient power steering fluid, which needs to be topped up. 3. Incorrect front wheel alignment, requiring a four-wheel alignment check. Additional related information is as follows: 1. Heavy left steering is caused by the hydraulic oil in the lower part of the steering power cylinder not forming working pressure or the working pressure being too low. The reasons for low pressure include: damage to the inner sealing rings at both ends of the steering rocker arm shaft; damage to the outer sealing ring of the radial groove (upper groove) in the valve body; improper installation or damage to the sealing rings on the upper and lower end faces of the oil passage leading to the bottom of the power cylinder in the intermediate cover. 2. Heavy right steering is caused by the hydraulic oil in the upper part of the power cylinder not forming working pressure or the pressure being too low. The reasons for this include: damage to or insufficient tension in the sealing ring inside the thrust needle bearing of the intermediate cover; damage to the sealing ring at the contact part between the intermediate cover and the housing, or improper installation or damage to the sealing rings on the upper and lower end faces of the oil passage leading to the power cylinder in the intermediate cover.
Last time I was driving, the steering wheel suddenly became extremely heavy, as if pushing against a wall, which really scared me. There are quite a few reasons for this, mainly issues with the power steering system, such as a faulty hydraulic power steering pump or low fluid levels; in my case, it was due to an aging oil pump seal that caused a leak, leading to insufficient pressure. Tire problems can also cause heavy steering, like low tire pressure or uneven wear, especially noticeable during sharp turns. Loose components in the suspension system can also affect the steering feel. If you notice this, don’t delay—get it checked at a repair shop right away. I had a new pump replaced in time to feel safe, otherwise losing control on the highway would be dangerous. Regular maintenance, like checking power steering fluid levels and tire pressure, can effectively prevent such incidents.
