Unbalanced wheel alignment

This is one of the most common causes, which can result from several factors. These include wheel weights falling off, causing the wheel to become unbalanced, or the technician lacking expertise in balancing the wheels at the service center.

Take the car to a skilled technician for wheel balancing. There are two methods of balancing wheels:

• Off-Car Balancing: This costs around 50-150 baht per wheel (depending on the shop)
• On-Car Balancing: This is more expensive, costing around 700-900 baht. This method is suitable if the first method doesn't resolve the issue

Bulging Tires

Bulging tires are an often unexpected cause because the issue can sometimes occur inside the tire, making it invisible to the driver. This usually happens from driving over potholes harshly, causing the tire's structure to deform. Additionally, tires that have been used for a long time can also develop bulges.

The only way to fix this issue is to replace the tire with a new one and properly align the wheels.

Another common problem that often confuses drivers is a “shaking steering wheel while braking.” If you notice the steering wheel shaking when driving at speeds of 50 km/h or higher, it could be due to warped brake rotors. In this case, the brake rotors need to be resurfaced to make them smooth again. If the rotors are too thin to be resurfaced, it is recommended to replace them with new ones.

If you notice these symptoms in your car, make sure to have it checked and fixed to ensure safe and smooth driving.
