If you’ve noticed a persistent clicking, clunking, or popping noise coming from your car’s front end—especially when turning, going over bumps, or accelerating—there’s a good chance a failing control arm is to blame. Control arms are critical suspension components that connect the wheel hub to the vehicle’s frame, allowing for smooth movement while keeping the wheels aligned. When they wear out, they don’t just cause noise—they can compromise handling and safety. In this guide, we’ll break down why control arms fail, how to diagnose the issue, and why Loosoo control arms are a trusted solution for drivers seeking reliability, affordability, and quality.
Why a Bad Control Arm Causes Clicking Noise: The Basics
Control arms rely on two key parts to function: bushings and ball joints. When either component wears out, you’ll hear telltale sounds:
1. Worn Control Arm Bushings
Bushings are rubber or polyurethane cushions that absorb vibration and prevent metal-on-metal contact between the control arm and frame. Over time, heat, moisture, and road debris cause them to crack, harden, or tear. When this happens:
- The control arm shifts excessively, creating a clicking or knocking noise when the wheel moves (e.g., turning or hitting a pothole).
- You may feel “play” in the steering wheel or notice uneven tire wear.
2. Loose or Damaged Ball Joints
Ball joints act as pivot points, connecting the control arm to the wheel hub. They’re sealed with a rubber boot to keep out dirt and retain lubricant. If the boot tears:
- Dirt invades, causing friction and wear. The joint becomes loose, leading to a clicking noise during turns (as the wheel pivots) or a “clunk” when accelerating/braking.
- In severe cases, a failed ball joint can cause the wheel to separate from the vehicle—never ignore this!
Other Symptoms of a Failing Control Arm
Clicking noise is often the first sign, but watch for these red flags too:
- Vibrations in the steering wheel at high speeds (due to misalignment from a loose control arm).
- Uneven tire wear (inner/outer edges wearing faster than the center).
- Pulling to one side while driving straight (the control arm can’t keep the wheel aligned).
- Excessive play when jacking the car (grab the tire and shake—if it moves horizontally, the ball joint or bushing is likely bad).
How to Diagnose: Is It the Control Arm or Something Else?
Clicking noises can also come from tie rods, sway bar links, or CV joints, so it’s important to narrow it down:
- Jack up the front end and secure the vehicle on stands.
- Gently shake the wheel side-to-side and up-and-down. Excessive movement (especially horizontal) points to a bad ball joint or bushing.
- Inspect the control arm visually: Look for cracked bushings, torn ball joint boots, or rust around the mounting points.
- Test drive: Listen for noise when turning sharply or going over speed bumps—control arm issues often worsen with these actions.
If you’re unsure, a mechanic can perform a “suspension bounce test” or use a pry bar to check for play in the control arm components.
When to Replace Your Control Arm
Don’t wait for the noise to get louder—address a failing control arm immediately to avoid:
- Further damage to tires, brakes, or other suspension parts (increasing repair costs).
- Reduced steering responsiveness, raising the risk of accidents.
Most control arms last 80,000–150,000 miles, but harsh road conditions (potholes, off-roading) or exposure to salt (in snowy climates) can shorten their lifespan. When replacing, opt for a complete control arm assembly (bushings and ball joints pre-installed) for easier installation and better long-term reliability.
