If your mechanic points to a cracked piece of rubber on a control arm during an inspection, you might wonder if it’s a minor wear-and-tear issue or something that needs immediate attention. The short answer is: It can be a serious safety concern, depending on the severity of the cracking. Ignoring deeply cracked or deteriorated control arm bushings can compromise your vehicle’s handling, tire health, and safety.
This guide will break down what control arm bushings do, the risks of driving with worn bushings, how to diagnose problems, and why upgrading to durable aftermarket solutions like MYWAY Bushings is a smart long-term investment.

1. What Are Control Arm Bushings and Why Do They Matter?
Control arm bushings are small but critical components in your car’s suspension system. They are rubber or polyurethane sleeves mounted where the control arm attaches to the vehicle’s frame. Here’s what they do:
Cushion Vibrations: They absorb shocks from road irregularities, providing a smoother ride.
Allow Controlled Movement: They enable the control arm to pivot smoothly during wheel travel.
Maintain Wheel Alignment: They help keep the wheels in the correct position for optimal handling and tire wear.
When these bushings crack or wear out, they can’t perform these roles effectively. The suspension system becomes less precise, leading to a range of problems that escalate from minor annoyances to major hazards.
2. What Causes Control Arm Bushings to Crack?
Bushing failure isn’t random. Here are the most common causes:
Age and Wear: Rubber naturally hardens and becomes brittle over time due to exposure to oxygen, heat, and ozone. Most OEM rubber bushings have a service life of around 100,000 miles under normal conditions.
Heat and Environmental Exposure: Bushings, especially front ones, are located near brakes and engines, which generate intense heat. This “bakes” the rubber, accelerating cracking. Road salt, oil leaks, and UV radiation can also degrade the material.
Stress from Driving: Constant twisting, compression, and impact from potholes or rough roads fatigue the rubber. Heavy loads, frequent towing, and aggressive driving put extra strain on them.
3. Symptoms of Worn Control Arm Bushings
Watch for these warning signs:
Clunking or Knocking Noises: A distinct “clunk” when going over bumps or during acceleration/braking often indicates excessive play from worn bushings.
Steering Wander or Vagueness: The vehicle may feel loose, requiring constant small steering corrections to stay straight—a sign the control arm isn’t held securely.
Vibrations Through the Steering Wheel: You might feel shimmies or shakes, especially at higher speeds.
Uneven Tire Wear: Worn bushings disrupt wheel alignment, causing irregular tread wear. This can shorten tire life significantly.
Visible Damage: During inspection, you may see:
Deep cracks (not just superficial surface cracks)
Rubber separation from the metal sleeves
Distortion or tearing of the bushing material
4. How Serious Is It? The Risks of Driving with Cracked Bushings
The seriousness depends on the extent of the damage:
Minor Surface Cracking
What it looks like: Small, shallow cracks in the rubber, similar to old tire sidewalls.
Risk Level: Low. This is often part of normal aging. You can monitor it and plan for replacement during routine service.
Moderate Cracking with Symptoms
What it looks like: Deeper cracks, possibly with minor separation. You might notice slight steering wander or occasional noises.
Risk Level: Medium. The bushing is failing. Address this soon to avoid accelerated tire wear and stress on other suspension components like ball joints and tie rods.
Severe Cracking or Separation
What it looks like: The rubber is deeply cracked, torn, or pulled away from its metal housing. The center sleeve may be visibly misaligned.
Risk Level: HIGH. This is a safety-critical issue. Consequences can include:
Dangerous Handling Changes: During hard braking or evasive maneuvers, the wheel can shift unpredictably, causing sudden pulls.
Complete Suspension Failure: In a worst-case scenario, a fully separated bushing could allow the control arm to detach, leading to loss of vehicle control.
Costly Collateral Damage: A failed bushing can cause rapid tire wear, misalignment, and damage to expensive components like shocks and springs.
Real-World Example: In 2022, General Motors issued a recall for certain 2016 Cadillac Escalade, Chevrolet Tahoe, and GMC Sierra models due to poorly welded front upper control arms. The recall noted that a failure could “affect steering and directional control of the vehicle, increasing the risk of a crash”. This highlights how critical these suspension links are.
5. When Should You Replace Control Arm Bushings?
Don’t wait for a complete failure. Replace your bushings if:
Any symptoms like clunking, wandering, or vibrations are present.
Visual inspection shows deep cracking, tears, or separation.
Your vehicle has high mileage (e.g., over 100,000 miles) and the original bushings have never been changed.
You’re already performing other suspension work—it’s often cost-effective to replace them while the system is disassembled.
6. Why Choose MYWAY Control Arm Bushings?
When it’s time for replacement, not all bushings are created equal. MYWAY Bushings are engineered for superior performance and longevity. Here’s how they solve the problems of cracked OEM bushings:
Robust Construction: Forged under high-tonnage pressure for a dense, void-free structure that withstands stress better than generic cast parts.

Extended Service Life: Designed to deliver a long service life, making them a reliable choice for drivers.
Improved Vehicle Dynamics: By maintaining precise control arm positioning, MYWAY Bushings help ensure consistent handling, reduce tire wear, and restore that solid, “like-new” feel to your steering.
Whether you drive a sedan, SUV, or light truck, MYWAY has a bushing solution tailored to deliver safety and performance you can count on.
7. Conclusion: Don’t Underestimate a Cracked Bushing
Cracked control arm bushings are more than just a maintenance item—they are a vital part of your car’s safety and performance. While surface cracks might only require monitoring, any cracking accompanied by handling changes or noises demands immediate action.

Frequently Asked Questions
1. Can I drive with slightly cracked control arm bushings?
Yes, for a short time—if the cracks are minor and no symptoms (noises, handling issues) are present. However, have them inspected at your next service. If cracks are deep or you notice any symptoms, replace them immediately.
2. How long can I drive with bad control arm bushings?
There’s no safe fixed mileage. Once symptoms appear, the situation deteriorates. Driving for weeks or months with faulty bushings risks safety and increases repair costs. Don’t delay.
3. Is it better to replace just the bushings or the entire control arm?
This depends:
Replace just the bushings if the control arm itself is in good condition and the labor to press out old bushings and install new ones is manageable.
Replace the entire control arm assembly (which typically includes new bushings and a new ball joint) if it’s more cost-effective. This is often recommended on high-mileage vehicles since other attached components (like ball joints) are likely worn too. It can save on future labor costs.
4. How much does it cost to replace control arm bushings?
Parts: A quality bushing set can cost $20 – $100 per bushing.
Labor: Typically $150 – $400+, depending on complexity and shop rates.
While cheaper options exist, investing in high-quality parts like MYWAY Bushings can prevent premature repeat repairs.
5. Can worn control arm bushings cause tire wear?
Yes, absolutely. Worn bushings allow the control arm to move excessively, disrupting wheel alignment. This often causes uneven tire wear, forcing you to replace tires prematurely.
