Why is the car steering wheel particularly heavy?
2 Answers
The main reasons for a suddenly heavy car steering wheel are as follows: 1. Power steering pump oil pipe leakage or oil cup shortage. 2. Power steering pump belt breakage causing the pump to stop working. 3. Power steering pump failure leading to non-operation. The main solutions for a heavy car steering wheel are: 1. Check if there is a fault in the power steering pump's oil pressure or oil circuit. 2. Visit a 4S shop for further inspection. Additional information: The working principle of a car steering wheel is: the car transmits torque to the rack and pinion mechanism by turning the steering wheel, thereby pushing the wheels to turn left or right. The longer the rack pushes, the greater the angle the tire turns.
A sudden increase in steering wheel heaviness may be related to power steering system issues. With years of driving experience, I've found common causes include insufficient or contaminated power steering fluid, which reduces hydraulic pump efficiency—you should check fluid levels and clarity. Secondly, wear in the steering pump or belt can also cause this; a loose or cracked belt diminishes power assistance. Additionally, low tire pressure affects steering feel—I always recommend checking if tire pressure meets standards first. Ignoring this issue may make handling difficult and even lead to steering failure, posing safety risks. I once experienced this on the highway and immediately pulled over—never force the vehicle to continue. Regular power steering system maintenance is crucial; check fluids every 5,000 km or six months to prevent costly repairs.
