Control Arm and Ball Joint Assembly
What is a control arm ?
The control arms are one of the core components of a suspension system and serve as the direct connection points between the front wheel assemblies and the vehicle's frame. The control arms allow a driver to steer a car while also guiding the wheels up and down with the road surface. Although they are simplistic in appearance, control arms have a vital role in a vehicle's overall stability and drivability.
The Functions of a Control Arm：
A control arm's purpose is straightforward. It connects the steering knuckle to the frame and stabilizes the vehicle by allowing the chassis and the wheels to move in unison while the vehicle is in motion. Ultimately, control arms help achieve coordination between the suspension and steering systems, dampening the ride and giving the driver the ability to maneuver the vehicle.
The control arm's swiveling ball joint serves as the steering system's pivot point, allowing the vehicle to be turned in either direction while moving forward or backward. The hinge joint on the control arms' frame side keeps the wheels in contact with the ground, whether traveling over smooth pavement or treading over bumps and potholes on the road. Both sides of the control arm work together to grant the movement necessary for a vehicle to safely and adequately operate on roads.
Control Arm Damage：
There are three primary types of damage to a control arm: frame damage, bushing damage, and ball joint damage. Frame damage can result from rust, extreme flexing, or breakage from a forceful impact or collision. Bushing damage generally occurs over time due to wear and tear. Ball joint damage is susceptible to wear and tear or even cracking due to moving parts that are always in contact.
A damaged or improperly functioning control arm will exhibit various symptoms, including vehicle vibration, a wandering steering wheel, misalignment, wobbly wheels, unusual grinding noises, fluctuations in braking, and uneven tire tread wear. If one or more of these issues are occurring, control arm replacement may be necessary. A mechanic will be able to make that determination.
What do ball joints do?
Ball joints are the critical component of the front suspension that connect various links and allow them to move. Ball joints consist of a ball and socket similar to the hip joint of the human body. Ball joints of your front suspension provide pivoting movement between the steering knuckles and control arms to provide a safe, smooth ride and allow you to precisely control your vehicle.
How Does The Suspension Ball Joint Operate?
The suspension ball joint is essential to a vehicle's suspension system. It allows the suspension system to move freely and absorb shock from the road. By allowing the suspension to move freely, the ball joint reduces the wear and tear on the suspension system, allowing for a smoother, more comfortable ride. The ball joint is a small, cylindrical metal connected to the steering knuckle and the lower control arm. It contains two sealed ball bearings, which allow it to rotate and absorb shock from the road. Between the bearings, a rubber boot used to keep dirt and moisture out helps extend the joint's life and keep it working correctly.
As the suspension moves up and down, the ball joint allows the wheels to move accordingly, keeping the vehicle's tire angle optimal. Without the suspension ball joint, the suspension system would be unable to move freely, and the vehicle would have a harsher, uncomfortable ride. Suspension ball joints need regular checks and maintenance.
The suspension ball joint can malfunction due to wear and tear. Friction from wear and tear causes the ball joint to become loose, leading to erratic movements. Dirt, grime, oil, salt, and other road debris can make it loose over time. A professional may inspect the suspension ball joint for any indication of wear or loose ball joints, such as faint, intermittent clunking noise or uneven tire wear.
When to Replace Suspension Ball Joints？
Given their role in the suspension system, ball joints experience daily wear and tear and, at some point, need replacement. Ball joints should need replacement when they show signs of wear and tear, such as clunking, rattling noises when the suspension moves, drifting to the side, and uneven tire wear. Ball joint replacement is not straightforward. It is necessary though, due to aging and rust. Parts made from premium materials are usually more durable, while parts made from low-grade steel can reduce the lifespan of the ball joint by up to 50 percent.
As a ball joint wears out, more space develops between the stud and the socket, which can cause issues. The constant movement of the ball stud can cause it to become loose and move around inside the socket. Your safety could be at risk if ball joints become too worn out — in severe cases, the stud can pull out of the socket and cause a wheel to become partially disconnected from the vehicle.
