Why Can't the Steering Be Corrected?
2 Answers
There are many reasons for understeering, which can be roughly divided into: insufficient power steering fluid; damaged bearings in the steering gear or steering column; lack of lubrication or damage to the tie rod ball joint; insufficient front tire pressure; or the meshing clearance between the steering pinion and rack being too small. Below is more information about steering: 1. Power Steering: Depending on the source of the power assistance, power steering is further divided into hydraulic power steering and electric power steering. Electric power steering responds faster and is more advanced than hydraulic power steering. Nowadays, better cars are equipped with electric power steering. 2. Four-Wheel Steering: This involves all four wheels turning simultaneously but at different angles. At low speeds, the front and rear wheels turn in opposite directions to reduce the turning radius and improve turning responsiveness. At high speeds, the front and rear wheels turn in the same direction to enhance vehicle stability and smoothness during cornering.
Once while driving, my steering wheel suddenly became hard to turn, and I had to use a lot of effort just to barely move it. Later, I found out it was a problem with the power steering system. Common causes include damage to the power steering pump or a loose belt, leading to loss of power assist; internal wear or jamming in the steering gear, causing the gears to get stuck and unable to turn; insufficient or leaking power steering fluid, reducing the assist; or sensor failure in electric power steering systems, causing signal errors and control failure. That time, I first checked the power steering fluid reservoir and found the level was low. After adding some fluid, it improved a bit, but in the long run, I needed to replace the pump. These issues are particularly dangerous, especially on highways where turning becomes difficult and accidents are more likely, so I immediately went to a repair shop. It's advisable to regularly check the condition of belts and fluids during maintenance, as timely replacement of worn-out parts can prevent most problems.
