What Causes Slight Jerkiness and Lack of Smoothness in the Steering Wheel?
2 Answers
Steering wheel slight jerkiness is caused by small turning clearance, faulty clock spring, steering angle sensor failure, or steering angle circuit issues. Below are the relevant explanations regarding steering wheel jerkiness: Small turning clearance: Friction between plastic components The steering wheel consists of various plastic parts. If the clearance is too small during rotation, abnormal noises may occur, especially in new cars, which usually improve after a break-in period. If the noise persists after break-in, try reinstalling the steering wheel. Faulty clock spring: Clock spring failure inside the steering wheel Those who have disassembled the steering wheel should pay special attention. It may be due to a broken clock spring or improperly connected clock spring plug. Replacing the clock spring or securing the plug can resolve the issue. Steering angle sensor failure: Use an automotive diagnostic computer to read the data stream from the steering angle sensor and analyze whether the data matches the actual situation to confirm the fault. If the steering angle sensor fails, a "steering angle sensor signal not credible" fault will appear. Replace the steering angle sensor. Covered by free replacement at authorized dealers during the warranty period. Sensor circuit failure: Remove the steering angle sensor and inspect its connecting wires for damage, cracks, or loose plugs to confirm the fault. If the steering angle sensor circuit fails, it cannot power the sensor, leading to this issue.
I've also experienced a slight stickiness in the steering wheel while driving, especially when turning or maneuvering. That unsmooth, jerky sensation is quite uncomfortable. Generally, in such cases, the first thing that comes to mind is an issue with the power steering system, such as a problem with the electric power steering pump or hydraulic circuit, leading to uneven force distribution. Secondly, insufficient or unbalanced tire pressure can cause wheel slippage, indirectly affecting the steering wheel's feel. Additionally, wear in the steering column bearings or tie rods can make the steering wheel feel jerky when turning. You can start by checking if the tire pressure and power steering fluid level are normal. If they're too low, inflate the tires or top up the fluid to rule out simple issues. If that doesn't help, it's best to visit a professional auto repair shop for a check-up to prevent the problem from worsening and affecting driving safety. Ignoring it for too long can accelerate wear in the steering system, making replacement parts more expensive.
