What Causes Difficulty in Turning the Steering Wheel on Rainy Days?
2 Answers
Possible reasons for difficulty in turning the steering wheel on rainy days include: 1. The steering wheel may have already been turned to its maximum limit, possibly one and a half or two full turns; 2. Low tire pressure in the steering tires: The tires may be squeezed and stuck due to excessively low pressure; 3. Issues with the steering wheel bearing: There could be a problem with the steering wheel bearing, or the power steering pump belt may have broken or internal components may be worn or damaged; 4. Steering gear failure: The steering gear may be faulty, the steering oil pipe may be clogged, or there may be a significant lack of oil. It is necessary to check whether the steering column is functioning properly, whether there is any oil leakage, and to inspect the front suspension for any abnormalities.
I also encountered a similar situation last time I drove in the rain, where the steering wheel became extremely heavy, almost as if it was welded shut. This is mainly because rainwater makes the road surface slippery, reducing tire grip, which causes the steering wheel to provide greater resistance. Additionally, if it's a car with electronic power steering, you should check whether the system has been exposed to water or if there's a short circuit in the wiring, as the high humidity during rainy days can easily lead to electrical faults. Another easily overlooked issue is the drag force caused by water-soaked brake discs, which can make steering more difficult. My suggestion is that the next time you encounter this situation, first slow down but avoid braking suddenly, then try turning the vehicle off and restarting it to let the electronic system perform a self-check. If you're on the highway, immediately turn on the hazard lights and pull over to inspect the tires.
