Lower the car window and try to listen to any noise coming from the car. If the driver hears any strange sound, focus on where they are coming from. Some strange sounds emanating from the suspension of cars such as:
Sound similar to knocks on the door
This sound occurs when there is a strong collision, and it means there are possible issues with the strut rods, strut rod bushing, and ball joints.
A continuous sound
The sound is continuous and gets bigger as the car moves faster. This happens when there is a malfunction in wheel bearings or an issue with the tires.
A rumbling sound
It sounds like there is a strong collision between metal bars, which can be caused by malfunctioning of bolts or broken connector parts.

Step #2: Check the exterior of the car.
When gathering enough information, the driver should drive the car somewhere empty and set up the handbrake system.
Be sure to let the engine cool down 30 minutes after the test drive is enough before starting testing the vehicle. Wear gloves and prepare the necessary items.
Step #3: Press down the car.
Carefully put your hands on the intersection of the hood and mud fender, press firmly on the suspension until the car bounces back. At that time, if the driver sees that the car could bounce back normally, this is a good signal that the strut is still working well. This way, the driver should try to check the struts at the 4 corners to see if they have any trouble.

Step #5: Check the vibration of the wheel.
Hold the tires tightly and start shaking wheels with your hand moving along the direction of 9h-3h and 12h-6h. If there is any unusual movement of the wheel, some parts of the vehicle may have been worn.
Note: Unusual motions can come from a variety of causes, so drivers should check and make accurate judgments.
