Control Arm Replacement Cost: Parts, Labor & Average Price

A control arm links the wheel assembly to the vehicle's frame and lets the suspension move up and down. Each front wheel usually has a lower arm and, on many vehicles, an upper arm too. When an arm bends, cracks, or wears out its bushings or ball joint, the car can clunk over bumps, wander on the road, or wear its tires unevenly.

The price of a replacement depends on the vehicle, whether the ball joint is built into the arm, how many arms you replace, and whether you go to a dealership or an independent shop. The figures below were checked on Oct 13, 2026 and come from Empire Auto Protect and a second published guide.

The typical independent shop price for one lower arm is $300 – $750. Dealership pricing runs higher, and so does the cost of replacing arms on both sides in one visit. Replacing a pair does not simply double the price, because the shop is already doing much of the same work and one alignment covers both sides.

Size and design drive the difference. A plain stamped steel arm on a compact car is cheap. A forged aluminum arm with an integrated ball joint on a late-model truck or a European luxury car costs more and can take longer to fit. The first table shows estimates for common models. The second shows vehicle classes from a different source, so the numbers do not line up exactly.

Two things set the part price: whether you buy an aftermarket or original equipment arm, and whether the arm comes with the ball joint and bushings already installed. A complete arm assembly costs more than a bare arm, but it usually saves labor, since the shop does not need to press out and replace the joint separately. Very cheap arms from overseas marketplaces are a poor way to save money on a part that holds your wheel in place.

Labor depends on the shop's hourly rate and how rusty or seized the fasteners are. Rural shops tend to charge less than shops in large coastal cities. Cars that spend winters on salted roads often take longer because bolts resist coming loose. The two sources below quote labor per arm.

Taking a control arm off changes the wheel's camber and caster, so a shop will normally recommend a four-wheel alignment afterward. Skipping it can wear down the inside edge of a front tire quickly. Ask whether the quote includes the alignment or lists it as a separate line.

Dealerships generally charge higher labor rates and use original equipment parts, which sit at the upper end of the part price range. They know the vehicle well and often back the work with a parts and labor warranty. Independent shops usually install quality aftermarket parts at a lower cost, and many offer their own warranty. Neither choice is wrong. Compare the written quotes, the parts brand, and the warranty terms rather than the total alone.

Published guides define the job differently. Some price a single lower arm with an alignment. Others price an arm only, or an arm with a ball joint pressed in. Vehicle mix, regional labor rates, and parts quality also differ, so two honest sources can land far apart.

Control arms are part of the suspension and steering geometry. A failing arm can change how the car handles, and in a severe case a part can separate. Warning signs include a clunk over bumps, a pull to one side, steering that feels loose, or a bent or cracked arm visible after an impact. If you notice any of them, have a qualified technician inspect the car soon. Do not delay the repair or keep driving hard on a worn suspension. This work involves lifting the vehicle, releasing spring tension, and torquing safety-critical fasteners, so it belongs with a trained technician.

• Which arm is worn. Upper and lower arms are priced differently, and some vehicles have several arms per wheel.
• Ball joint design. An integrated joint raises the part price and lowers the labor.
• Part quality. Original equipment, quality aftermarket, and low-cost arms differ in price and durability.
• Number of arms. Doing both sides at once costs less than two separate visits.
• Rust and age. Seized bolts add time.
• Location. Labor rates vary a great deal by region.
