Reasons for Slight Steering Wheel Vibration and Hand Numbness
2 Answers
Steering wheel vibration is caused by engine shaking. Severe shaking is primarily due to excessive carbon deposits in the engine, throttle valve, fuel injectors, or intake manifold leading to cylinder misfire; or insufficient power caused by low oil pressure or cylinder pressure. Below are the relevant explanations: 1. Engine carbon deposits: A very common cause of car shaking is a dirty throttle valve or excessive carbon buildup in fuel injectors. Solution: Clean the fuel system and check for carbon deposits in the idle control valve. 2. Ignition system issues: Inspect the condition of spark plugs, high-voltage wires, and ignition coils. Poor performance in the ignition system or improper spark plug firing can also lead to such symptoms. Solution: Check if spark plugs have excessive carbon deposits and replace them if necessary.
I've experienced slight steering wheel vibrations and numbness in my hands after driving for many years. At that time, the steering wheel kept shaking like a phone vibrating, and after a while, my arms would feel uncomfortable. This is usually caused by unbalanced tires, where the weight distribution is uneven when the wheels rotate, or it could be due to tire wear or deformed rims from hitting potholes too hard. Additionally, loose suspension components, such as damaged control arms or shock absorbers, can also cause this. If left unchecked, the vibrations will worsen, affecting steering precision and increasing fuel consumption. It's important to go to a repair shop for a thorough inspection. Replacing tires or performing wheel balancing usually solves the problem. Avoid driving over potholes at high speeds to save yourself a lot of trouble.
