What Causes Difficulty in Steering Wheel Rotation After Multiple Reversing Maneuvers?
2 Answers
It is possible that heavy braking during reversing triggered the auto start-stop system, causing the power steering system to lose power; alternatively, prolonged steering wheel rotation may have activated the system's overheating protection or damaged the power steering pump. Owners should promptly send the vehicle for inspection and repair. The reasons for a heavy steering wheel are as follows: 1. Insufficient power steering fluid: Power steering fluid is a medium oil used in the vehicle's power steering pump, serving to transmit steering force and provide cushioning. This fluid requires regular replacement, and leaks should be checked. When the power steering fluid is insufficient, the steering will feel heavy and stiff. 2. Low tire pressure: Low tire pressure increases the contact area between the tires and the road surface, raising friction and making steering more difficult, resulting in a heavy steering wheel. This is not conducive to driving safety, and tire pressure should be promptly replenished in such cases. 3. Overly tight bearing fit: For the rolling bearings connected to various steering systems, if they fit too tightly with sliding bearings, it can prevent proper lubrication and operation, leading to sticking phenomena and a heavy steering wheel. In such cases, the mechanical parts and power steering system should be inspected, or checked for oil leaks and damaged intake manifold seals. 4. Power steering system issues: The steering wheel and power steering system are closely related. Therefore, when the steering wheel becomes very heavy, it is likely that there are internal issues in the power steering system, such as poor electrical contact or other problems. In such cases, the vehicle should be taken to a 4S shop for inspection and repair.
With over 10 years of automotive repair experience, this issue commonly occurs in power steering system failures. The steering wheel becoming heavy after multiple reverse maneuvers may indicate steering fluid leakage or insufficient levels, causing a drop in power steering pump pressure and making steering difficult to operate smoothly. Examples include aging/cracked steering hoses, worn seals, or overheated/worn power steering pump bearings. Frequent steering during reverse maneuvers increases load, making these underlying issues more likely to surface. Additionally, electronic power steering systems may suddenly malfunction if the motor overheats or the control module fails. I recommend first checking the steering fluid level—if low or contaminated, promptly top up or replace it. Simultaneously, listen for abnormal noises from the power steering pump; if present, visit a professional repair shop as soon as possible. Safety first—never ignore minor warning signs to prevent accidents.
