Suspension Control Arms: What to Know Before Buying at Advance Auto Parts

When your vehicle's suspension starts feeling loose or you notice uneven tire wear, the control arms might be the culprit. These critical components connect the wheels to the frame and allow controlled vertical movement. If you're shopping for replacement suspension control arms, Advance Auto Parts offers a wide selection. Here's what you need to know to make an informed choice.

What Are Suspension Control Arms?

Control arms are pivot points that link the steering knuckle (or wheel hub) to the vehicle's frame or subframe. They allow the suspension to move up and down while keeping the wheels aligned. Most vehicles have both upper and lower control arms, though some designs only use lower arms.

Types of Control Arms

• Stamped Steel: Factory equipment on many vehicles. Durable and affordable, but heavier.
• Forged Steel: Stronger and more resistant to bending. Common on trucks and SUVs.
• Aluminum: Lightweight and corrosion-resistant. Often used in performance or luxury cars.
• Adjustable: Allow camber and caster adjustments for lowered or modified suspensions.

Signs You Need New Control Arms

• Clunking or knocking noises over bumps or when turning.
• Vague steering or wandering on the highway.
• Uneven tire wear (especially inner or outer edges).
• Visible damage: cracks, bent arms, or torn ball joint boots.
• Failed alignment that can't be corrected.

If you notice any of these, inspect the control arms and their bushings and ball joints. Often, the ball joint or bushing fails before the arm itself, but replacing the entire assembly saves labor time.

Control Arms vs. Complete Assemblies vs. Individual Parts

When shopping at Advance Auto Parts, you'll see several options:

Bare Control Arm

Just the metal arm. You'll need to press out old bushings and ball joints and install new ones. This is more labor-intensive but often cheaper.

Complete Control Arm Assembly

Comes with new ball joints, bushings, and sometimes even a tie rod end. Bolt-on replacement – no pressing required. Ideal for DIYers because it saves time and ensures all components are new.

Ball Joint Only

If only the ball joint is worn, you can replace just that. But if the bushings are also old, it's smarter to replace the whole arm.

At Advance Auto Parts, look for brands like Duralast, MOOG, and ACDelco. Duralast offers a lifetime warranty on many parts, which is a plus for budget-conscious shoppers.

How to Choose the Right Control Arms

Vehicle Compatibility

Use the online fitment filter on Advance Auto Parts' website. Enter your vehicle's year, make, model, and engine. Always double-check with your vehicle's service manual.

Quality vs. Cost

• Economy: Duralast or similar. Good for older cars with moderate mileage.
• OE Quality: MOOG problem-solving parts often include improved grease fittings or stronger bushings.
• Performance: Brands like Energy Suspension for polyurethane bushings, but be aware they increase NVH (noise, vibration, harshness).

Bushings

• Rubber: Comfortable, quiet, but wear faster. Good for daily drivers.
• Polyurethane: Stiffer, more responsive, but can squeak. Better for performance or towing.
• Hydraulic: Filled with fluid for damping. Found on some luxury vehicles.

Ball Joints

• Non-greaseable: Sealed for life. Convenient but cannot be lubricated.
• Greaseable: Have a zerk fitting for periodic greasing, extending lifespan. Preferred by many mechanics.

Installation Considerations

Replacing control arms requires basic mechanical skills and tools: jack, jack stands, sockets, torque wrench, and possibly a ball joint press (if not using complete assemblies). If you're unsure, have a professional install them. Improper installation can lead to alignment issues or even failure.

After installation, a wheel alignment is mandatory. Drive a few miles to settle the suspension, then align.

Recommendations for Buying at Advance Auto Parts

• For most drivers: A complete control arm assembly from Duralast or MOOG. It's a bolt-on replacement with new bushings and ball joints. Check the warranty – Duralast Gold has a limited lifetime warranty.
• For trucks or heavy use: MOOG or ACDelco professional-grade arms. They often have reinforced ball joints.
• For performance or lowered cars: Look for adjustable arms with polyurethane bushings. Brands like SPC or Eibach may be available online but check in-store.
• If budget is tight: Consider a bare arm and press in new bushings and ball joints yourself. But account for the cost of a shop pressing the old parts.

Final Tips

• Before buying, check if the arm includes the ball joint and bushings. Read the product description carefully.
• Use the Advance Auto Parts website or app to check inventory at your local store. You can often pick up same-day.
• Take advantage of online coupons or loyalty rewards. Sign up for SpeedPerks to earn points.
• If the control arm is part of a larger project (e.g., replacing struts or shocks), do all related work at once to save on alignment costs.

Choosing the right suspension control arms keeps your ride safe and comfortable. With the options at Advance Auto Parts, you can find parts that fit your vehicle and budget. Just match the quality to your driving needs.

Conclusion

Suspension control arms are vital for steering and tire life. Whether you need one or all four, Advance Auto Parts stocks a range of options from budget to premium. Focus on complete assemblies for easy replacement, and always install new bushings and ball joints. A proper alignment afterward ensures your vehicle handles as designed. For most vehicles, a Duralast or MOOG complete arm offers the best balance of cost and reliability. If you drive a truck or work vehicle, consider upgrading to a heavier-duty brand. With these guidelines, you can confidently pick the right suspension control arms for your next repair.
