Control Arm

Control arms are part of the suspension which locates and controls the movement of the hub and strut. There are usually a couple control arms on each corner of the vehicle. They also have bushings and ball joints which is usually why they need replacement ovetrtime, since those are wear items. The cost to replace varies depending on the vehicle. Control arms cost different amounts depending on the vehicle, as well as the labor to install. Some are easy to install and take little time, while others can take several hours.

Likely the replacement control arm comes with new bushings, although I'm not an expert in that particular car.  Most come as a unified assembly these days, and for a car as widely produced as the Accord, you could probably replace the entire unit for cheaper than just replacing just the bushings, but I'm not an expert in that particular car. Its always worth it to replace bushings on control arms.  I wouldn't mess with anything that has to do with integrity of the front suspension, unless you live somewhere where the roads are perfect and pristine, you never have to make evasive maneuvers, and you don't ever turn.   It also can substantially effect the front end alignment, depending on how worn it actually is, which effects how straight the car goes on the highway, and how well it responds to steering input.Front ends, while really sturdy, need to be intact to be operate as designed.   I realize you may not want to spend any money on it and want it to last another year, but its an  unfortunate false economy to not replace a control arm bushing.

Those are the bottom most mounts for your front wheels spindles. They set a lot of your alignment parameters and certain bearing surfaces becoming loose can cause steering and tire wear issues.They can also be bent from collision and abuse.

Ball Joint in Control Arms: The Pivot Point of Your Suspension 1. Core Function The ball joint is a pivotal component connecting the control arm (or A-arm) to the steering knuckle (or wheel hub). It serves as a multi-axis swivel point, enabling two critical movements: Vertical motion: Absorbs bumps by allowing the wheel to move up/down. Horizontal rotation: Facilitates steering by pivoting the wheel left/right. 2. Key Roles in Suspension Load Bearing: Supports the vehicle’s weight while maintaining wheel alignment. Flexibility: Combines rigidity (for stability) and articulation (for smooth ride). Precision Steering: Ensures responsive handling by minimizing play in the linkage. 3. Design & Components Ball-and-Socket Design: A spherical bearing (ball) rotates within a lubricated housing (socket), sealed by a rubber/plastic boot to keep out dirt/moisture. Types: Load-bearing (upper/lower joints in MacPherson strut systems). Follower-type (non-weight-bearing, common in double-wishbone suspensions). 4. Failure Symptoms Clunking noises over bumps (excessive wear). Vibration/loose steering (joint play). Uneven tire wear (misalignment due to joint failure). 5. Maintenance Tips Regular inspection: Check for torn boots or grease leaks. Avoid impacts: Potholes/curbs accelerate wear. Non-serviceable vs. serviceable: Some modern joints are sealed (replace entire unit), while others allow regreasing. Analogy: Think of it like your shoulder joint—it must be strong enough to carry weight but flexible enough to rotate freely! Why It Matters A failing ball joint can lead to loss of wheel control—a critical safety hazard. In many vehicles, it’s integrated into the control arm assembly, requiring full replacement.

A control arm is a crucial component of a vehicle's suspension system, connecting the wheel to the vehicle's chassis. Its primary function is to control the wheel's movement, allowing it to move up and down while maintaining its proper alignment with the body of the vehicle. Control arms typically come in pairs: an upper control arm and a lower control arm. They can be designed in various shapes and made from different materials to meet specific performance needs. By controlling the wheel's motion, control arms help the vehicle better respond to uneven road surfaces, providing a smoother driving experience and improving handling and safety. Additionally, control arms assist in absorbing impacts from the road, reducing the direct effects on the vehicle's body. In summary, control arms play a vital role in the suspension system, contributing significantly to driving comfort and safety.
