What causes the steering wheel of the Arrizo 5 to shake left and right at 90 km/h?

[McAbel]

Reasons for the steering wheel of the Arrizo 5 shaking left and right at 90 km/h: 1. Play in the chassis ball joint: When the vehicle is moving at high speed, there will be some movement allowance, causing shaking. Check the ball joint and replace any damaged ones. 2. Loose steering wheel shaft: Inspect the steering wheel system and replace any damaged components. 3. Incorrect wheel dynamic balance: Perform dynamic balancing on the tires. Precautions for tire dynamic balancing: 1. Do not touch the tire while it is rotating, as it may cause danger. 2. Clean the inside of the tire thoroughly; otherwise, the balancing weights may fall off.

I've encountered a similar issue before. When driving my Arrizo 5 at speeds above 90 km/h, the steering wheel starts to shake, wobbling left and right, which is very uncomfortable. The most common cause is improper tire dynamic balancing. When the wheels are unbalanced at high speeds, it can cause resonance, leading to left-right shaking of the steering wheel. Severe tire wear or uneven tire pressure can also cause this, such as one tire wearing more on one edge. Issues with the suspension system, like damaged shock absorbers or loose tie rods, can affect wheel stability. Additionally, deformed rims or aging steering ball joints may also lead to this problem. If not addressed promptly, severe shaking increases the risk of losing control, especially at high speeds. It's recommended to first check tire wear and pressure. If everything seems fine, it's best to visit a shop for balancing correction or a comprehensive inspection to ensure smooth and safe driving.

I analyzed this phenomenon from a mechanical perspective. Steering wheel shaking at 90 km/h typically stems from issues with wheels or chassis components. Unbalanced tires are the most common cause, where uneven force distribution during high-speed rotation induces vibration. Tire wear, inconsistent tire pressure, or deformed wheel hubs can exacerbate this condition. Components in the suspension system, such as leaking shock absorbers or worn support arms, may lead to wheel alignment deviations. Loose tie rods or ball joints in the steering system can make the steering wheel more prone to shaking. In vehicles like the Arrizo 5, problems with the drive shaft might also indirectly contribute. When shaking occurs only at specific speeds like 90 km/h, it's often due to triggering a resonance point. Performing dynamic balancing tests promptly or using professional equipment to inspect suspension components can effectively identify the root cause. Maintaining regular vehicle maintenance is crucial to prevent issues from worsening and affecting handling performance.
