Rear AAG replacement typically costs between $400 and $1,200 per side, depending on your vehicle make and model, whether you choose OEM or aftermarket parts, and your location.

An AAG (anti-roll bar link, also called a sway bar link) is a small rod that connects your anti-roll bar to the suspension. When it wears out, you lose some of the suspension's ability to control body roll during turns, and you may hear clunking or knocking from the rear wheels. Replacing one is straightforward work, but the total bill depends on parts cost, labor rates at your shop, and whether you're replacing one side or both.

Most independent shops charge $150 to $300 in labor per side. Dealerships typically charge $200 to $400 per side. The parts themselves run $100 to $400 each for OEM (original equipment manufacturer) parts, or $50 to $150 for quality aftermarket replacements. If both rear AAGs need replacement — which is common, since they wear at similar rates — you're looking at doubling the parts cost but adding only modest labor time for the second one.

Key Takeaways

  • A single rear AAG replacement at an independent shop typically costs $250 to $600 total, including parts and labor.
  • Dealership prices run higher, usually $350 to $800 per side, because they charge more for both labor and OEM parts.
  • Aftermarket AAGs cost less than OEM parts but perform the same function; the labor cost is identical either way.
  • Replacing both rear AAGs at once costs less per side in labor than replacing them separately, so shops often recommend doing both if one is worn.

How parts cost breaks down

The AAG itself is the main variable in your parts bill. OEM parts from your vehicle's manufacturer cost $150 to $400 depending on the brand — luxury vehicles and trucks run higher. Aftermarket AAGs from brands like Moog, Dorman, or TRW cost $50 to $150 and carry the same warranty as OEM parts at most shops.

Some vehicles also need a new mounting bracket or bushing when the AAG is replaced, which adds $30 to $100 to the parts cost. Your mechanic will tell you during inspection whether these are necessary. A few high-end vehicles require a wheel alignment after AAG replacement, which adds $100 to $200 if your shop charges separately for that service.

Labor costs at different shop types

Independent repair shops typically charge $150 to $300 per side in labor. This is the most common route and usually the lowest total cost. The job takes 30 minutes to an hour per side if no complications arise.

Dealerships charge $200 to $400 per side in labor, sometimes more in high-cost urban areas. You're paying for the dealership's overhead and their technicians' training on your specific vehicle model. Dealerships also tend to charge more for OEM parts themselves.

Chain shops like Firestone or Midas fall between the two, usually $175 to $300 per side. They stock common aftermarket parts and can often schedule you faster than independent shops, but you have less control over which parts they use.

Why replacing both sides at once usually makes sense

If one rear AAG is worn enough to need replacement, the other is typically close behind. Both sides wear at the same rate because they handle the same forces. Replacing only one side means you'll likely return in a few months for the other, paying labor twice.

Most shops will quote you for both sides if they find one is bad. The second side's labor cost is often discounted slightly — sometimes $20 to $50 off — because the technician is already under the vehicle and has the tools out. The parts cost straightforward doubles, but you avoid a second service visit.

What affects your actual quote

Your vehicle's make and model is the biggest factor. A Honda Civic rear AAG replacement costs less than a Ford F-150 or a BMW, because the parts are cheaper and the labor time is shorter on the Civic. Luxury brands and trucks consistently run higher.

Your location matters too. Shops in urban areas and coastal regions charge more than rural shops. A rear AAG replacement that costs $500 in a small town might cost $750 in a major city.

Whether the AAG is stuck or corroded affects labor time. If it's seized to the suspension arm, the technician may need extra time to remove it, which can add $50 to $100 to the labor charge. This is rare but happens more often in older vehicles or those in salt-heavy climates.

Getting an accurate quote

Call or visit three shops — an independent, a dealership, and a chain shop — with your vehicle's year, make, model, and mileage. Tell them you need a rear AAG replacement and ask whether they recommend doing both sides. Ask specifically whether the quote includes alignment or any other work.

A written quote should list the parts cost, labor cost per side, and total. If the shop says "it depends on what we find," ask them to give you a range. Reputable shops will also tell you whether they use OEM or aftermarket parts, or ask which you prefer.

Don't assume the cheapest quote is the best. A shop quoting $250 per side might be using very low-quality parts or rushing the job. A shop quoting $600 per side might be overcharging. The middle range — $350 to $500 per side at an independent shop — is usually the sweet spot for quality and fair pricing.

Frequently Asked Questions

Can I drive on a bad rear AAG?

Yes, but you'll notice clunking or knocking when turning, and the rear end will feel less stable in curves. It's not an emergency repair, but don't ignore it for months — a completely failed AAG can affect handling enough to be unsafe in emergency maneuvers.

Is there a big difference between OEM and aftermarket AAGs?

No. Both are engineered to the same specifications and carry similar warranties. Aftermarket parts from established brands like Moog perform identically to OEM parts and often cost half as much. Choose aftermarket unless your dealership strongly recommends OEM for your specific vehicle.

Will my check engine light come on if an AAG fails?

Not usually. A bad AAG causes noise and handling changes, but it doesn't trigger the engine computer. If your check engine light is on, that's a separate issue your mechanic should diagnose.

How long does a rear AAG replacement take?

About 30 minutes to an hour per side if everything goes smoothly. If the shop is busy, the job might sit in the queue for a few hours before the technician starts. Most shops can complete both sides in a single day if you drop the car off in the morning.

Do I need an alignment after replacing a rear AAG?

Not always. Most shops don't recommend it unless your vehicle already had alignment issues or the AAG replacement involved moving suspension components. Ask your mechanic — they'll tell you if alignment is necessary based on what they find during the job.
