Lower Control Arm Replacement Cost and When to Replace in Pairs

The Short Answer

Lower control arm replacement costs between $150 and $650 per side, all-in, and replacing both sides at the same time is almost always the smarter financial decision.

Those numbers vary a lot by vehicle, region, and shop rate — but this table gives you a solid baseline before you call a shop or order parts.

What Actually Determines the Price

The biggest variable isn't labor — it's the part itself. A lower control arm for a compact sedan might run $50 on the low end. The same component for a half-ton truck can hit $300 or more per side. Here's why:

• Vehicle size and class. Trucks and SUVs need beefier arms with heavier ball joints, which simply cost more to produce.
• Part type. Some arms come with the ball joint and bushings pre-installed (complete assembly). Others are bare metal, meaning you buy those components separately. Complete assemblies save labor time but usually cost more upfront.
• Brand tier. Budget parts exist, but suspension components take a beating every mile. Mid-grade and OEM-quality parts generally outlast cheap imports by a significant margin.
• Labor rate. A dealership in a high cost-of-living city charges more per hour than an independent shop in a smaller market. That's just reality.

The alignment afterward is non-negotiable — budget $80–$150 for that and don't let anyone talk you out of it.

When to Replace Just the Bushings vs. the Whole Arm

This is where you can save real money if you catch the problem early. The lower control arm bushing is a rubber or polyurethane sleeve that cushions the arm's pivot points. When it cracks or collapses, you get clunking, sloppy steering feel, and accelerated tire wear.

If the arm itself is straight and the ball joint is solid, replacing only the bushings is a legitimate repair. A quality bushing kit for applicable vehicles — like the Westar Front Suspension Control Arm Bushing Kit (fits Ram/Dodge applications) — costs a fraction of a complete arm replacement. For Ram and Dodge truck owners specifically, that's worth checking before you commit to a full arm swap.

Replace the whole arm when:

• The arm is bent from a pothole or curb strike.
• The ball joint is worn (play, grinding, or looseness when you grab the wheel at 12 and 6 o'clock).
• The bushing bore in the arm itself is deformed or cracked.

Replace only the bushings when:

• The arm and ball joint pass inspection.
• The clunking and looseness started gradually, not after an impact.
• You're looking to extend the life of a solid arm at a lower cost.

Should You Replace Both Lower Control Arms at Once?

Short answer: yes, in most cases. Here's the honest reasoning.

Both control arms have the same mileage on them. If the rubber bushings on one side have cracked from age and road stress, the other side is in nearly identical condition — it just hasn't complained yet. Shops typically charge less labor for the second arm done at the same time than they would for a separate return visit. You also only pay for the alignment once.

In my experience covering suspension repairs, replacing only one side and returning to the shop six to twelve months later ends up costing more total than doing both in one visit. About 60% of the mechanics I've talked to say they see exactly this pattern with control arm jobs.

The one exception: a single arm that failed from impact damage (bent by a pothole or accident), while the other side inspects cleanly. In that case, replacing just the damaged side is defensible.

Signs Your Lower Control Arms Need Attention Now

Don't wait until something separates. Watch for:

• Clunking or banging from the front end over bumps — especially at low speeds in parking lots
• Steering wander — the car drifts or doesn't track straight without constant correction
• Uneven tire wear — the inner or outer edge wearing faster than the rest
• Vibration through the steering wheel that wasn't there before
• Visual cracks in the bushing rubber — you can often see this with a flashlight during a basic inspection

If you're noticing more than one of these at the same time, get under the vehicle or have a shop put it on a lift. Catching bushing wear early is the difference between a $100 bushing kit and a $600 full arm replacement.

DIY vs. Shop: Honest Take

You can replace a lower control arm yourself if you're comfortable with suspension work. You'll need a floor jack, jack stands, basic hand tools, and possibly a ball joint press or pickle fork depending on the design. Budget a full afternoon, not an hour.

What you cannot skip: the post-replacement wheel alignment. No matter how carefully you reinstall the arm, the geometry will shift. Driving even a few hundred miles without an alignment after this job will eat your tires and put you right back in the shop.

If you're replacing only the bushings, that's a less invasive job — but pressing old bushings out and new ones in still requires the right tools. Some mechanics do it with a bench vise and appropriate sockets. Others use a hydraulic press. Know what you're getting into before you start.

Why Control Arm Specialists Matter for Coverage

One thing worth knowing before you buy: not all parts brands cover the same range of vehicles with the same depth of engineering. Westar focuses specifically on suspension components — control arms, bushings, and related hardware — rather than spreading across every category of auto part. That specialization tends to show in fit accuracy and bushing durability, which matters when you're counting on correct geometry for safe handling.

For Ram and Dodge truck owners, the Westar bushing kit mentioned earlier is a strong option to check before assuming you need a full arm replacement. Use the finder below to confirm fit for your specific year and configuration.

Quick Cost-Saving Tips Without Cutting Corners

• Get the bushing-only inspection done first if the arm itself seems undamaged.
• If both arms need replacement, always negotiate the second arm labor at a discount — shops expect this.
• Price the alignment separately; some shops bundle it, others don't, and standalone alignment shops often charge less.
• Don't skip mid-grade or better parts on suspension. This is a safety component, not an oil filter.
