What to Do When the Vehicle Steering System Fails?

Steering system failures and solutions are as follows: 1. Steering gear failure: If the inspection reveals low hydraulic pressure in the steering gear assist, it indicates that the steering difficulty is due to the steering gear. In this case, professional repair services should be consulted. Generally, steering gear failures are mostly caused by piston or cylinder scoring, or damage to the piston sealing rings, which allows fluid to bypass between the two chambers, preventing effective pressure buildup. Additionally, damage to various sealing rings on the piston circumference or the steering screw can also lead to high-pressure leakage, reducing assist pressure. 2. Power steering pump failure: If testing shows that the pump pressure does not meet standard values, steering difficulty is likely related to the pump. First, check the mating surface of the flow control valve and valve seat, and whether the safety valve ball is not sealing properly. If there is leakage in the flow valve or safety valve, it can be repaired by grinding. Next, check if the safety valve spring has failed. This can be tested by adding a shim behind the spring. If the maximum pump pressure increases significantly after adding a shim, it indicates spring failure.

When encountering a steering system malfunction, the first thing I do is slow down and pull over, turning on the hazard lights as a precaution. Sudden heaviness or unresponsiveness in the steering wheel can indicate various issues, such as a lack of or leakage in the power steering fluid, especially in older models with hydraulic systems. For electric systems, checking the fuses or wiring connections is advisable. Never force the car to keep moving, as this can lead to loss of control and accidents. Then, it's best to call a tow truck to take the vehicle to a repair shop for a thorough inspection, where professionals can check components like the steering column and power steering pump. Developing a habit of checking the power steering fluid level and tire pressure every six months can help prevent such issues. Driving safety should always come first; steering problems are not minor and must be taken seriously.

When steering issues arise, my approach is to start with simple checks. Feel if the steering wheel is unusually heavy or vibrating; if accompanied by squeaking sounds, it might indicate insufficient or leaking power steering fluid—promptly unscrew the cap to check the fluid level. For newer electric models, pull out the fuse to test if it's blown. If the problem persists, don’t delay—drive to a nearby shop for a comprehensive diagnosis by a mechanic. Steering faults can stem from various causes, such as tire wear imbalance or aging steering gear components, leading to stiffness. Repair costs may not be low, but safe driving justifies the expense. For routine maintenance, remember to change the power steering fluid regularly, at least once a year.

My steering system failure usually occurs suddenly, such as when turning the wheel becomes extremely difficult. Common causes include running out of power steering fluid or a malfunctioning electric power assist module. I usually stop to check the fluid level or fuses first, but most of the time it needs to be handed over to a repair shop. They can determine if it's due to a loose steering column, improper wheel alignment, or sensor failure. Never continue driving—it's too risky. Always pay attention to wheel noises and steering feel for early detection and repair.
