The suspension ball joint is a critical component that connects the wheel to the vehicle's chassis. Its primary functions are to transmit steering forces, support the vehicle's weight, and ensure stability and safety during driving.

Structure and Function
A suspension ball joint typically consists of a steel ball and a socket. The steel ball can rotate freely within the socket, enabling multi-directional movement. This design allows the wheels to steer flexibly and adapt to bumps and body roll under various road conditions.

Installation Location

• In front-wheel drive vehicles, it is installed between the half-shaft and the wheel.

• In rear-wheel drive vehicles, it is installed between the transmission output shaft and the input shaft of the drive axle's differential.

Consequences of Damage
If a suspension ball joint is damaged, it may lead to issues such as abnormal noises while driving, impaired steering control, or uneven braking (brake pulling). Timely replacement is essential.
