A car’s suspension repair cost can be significant. There are several parts to it, all of which are bound to fail at some point.
Anticipate the cost of repairing your suspension to be around $200 to $400, based on what’s causing the issue.
Parts of your suspension that could go wrong include the coil springs, shock absorbers (“shocks” or, technically, “dampers”), wishbone, drop-links, and MacPherson struts.
Don’t put repairs off when your suspension fails, as it unavoidably will at some point.
Get it fixed immediately to ensure your car is safe (and snug) to drive.
I will now elucidate the fundamentals of car suspensions before moving to the repair cost.

How Does Car Suspension Work?
Vehicle suspension is essentially everything that absorbs impact from the road. It protects its occupants and drivetrain from these vibrations and jolts.
It includes the wheels and tires, steering system, torsion bars and differentials, chassis, and the standard “shocks and springs” components.
The coil spring is the most vital part of your car’s suspension. It’s basically the same as any other spring you might be visualizing (except, of course, it’s robust enough to bear a quarter of the weight of a vehicle).
When you go over a bump in the road, the spring compresses, decelerating the speed with which the car’s body jars. It then releases, returning the vehicle to normal.
Well, in theory. In reality, springs would be bouncing around all over the place. Our roads are never exactly level, so the car would be impossible to control. It would look something like those low riders from Mexico and the southern states.
That’s where dampers come in. Dampers use a hydraulic fluid-and-piston-based system. The harder the impact, the greater the opposing force it applies.
They help absorb substantial impacts and return the car to its stable rest position within one spring bounce.
In the front of the car, the shock absorbers are integrated into the struts (typically “MacPherson struts”).
At the back of your vehicle, they’re attached independently to the suspension arm on each side. The identical is true for the rear coil springs.
How Do Leaf Springs Work?
Leaf springs are used on heavy-duty vehicles like trucks, serious off-roaders, and delivery vans. Leaf springs have been used in transportation for many years – long before the invention of the car, even!
This is made of metallic sheets stacked up in a “U” shape.
Leaf springs are much more durable than coil springs. They can handle significant loads but make the vehicle feel pretty stiff. You’ll feel every little jolt the road has to throw at you. They’re also rather large and heavy compared to coil springs and much more challenging to fine-tune.
For these reasons, it’s not usually a prudent idea to fit passenger cars with leaf springs. It’s better to have a lighter, more compact, and more comfortable suspension system.
With that being said, the enumerated cars possess leaf springs: the Pontiac Trans-Am, Shelby GT350 Mustang, Chevrolet Corvette Stingray C7, Toyota Tundra, Land Rover Defender, and Volvo XC90.

What Can Go Wrong With Car Suspension?
When it comes to car suspension, any of the elements can fail.
Two of the most common to watch out for are broken springs and leaking shock absorbers.
Coil springs break when they either rust away – very common in moist parts of the world – or suffer an intense, abrupt load (like a nasty pothole). Usually, the spring snaps somewhere near the top or bottom. The rest of the spring then expands and remains relatively in place.
You’ll need to get a fresh spring as soon as possible. A mechanic can’t repair it.
Shock absorbers (“dampers”) are likely to develop leaks over time. That said, they, too, can break due to severe impacts. Shock absorbers work through a hydraulic piston system. If the fluid leaks, they cease functioning. They can also freeze up.
Once more, you’ll need a new damper. It’s impractical to repair.
Many other things can also go wrong, although these are the principal things to watch out for.
How Much Does It Cost To Replace A Suspension System?
A vehicle suspension replacement expense is made up of labor and parts.
In this section, you’ll find approximations of how much it costs to fix your suspension, broken down into these categories. Bear in mind that these prices can vary substantially based on your mechanic’s hourly labor rate and the quality of the components you or they purchase.
It’s generally advised to replace suspension in pairs across the axle. However, for some individuals, the cost can’t be justified. It’s suggested but not crucial.
Coil Spring Replacement Cost
Replacement coil springs will cost around $150 to $200 per side. This consists of $40 to $100 for the parts and around an hour’s labor.
Rear coil springs will be slightly less, at around $100. Although the parts might be a similar cost, they’re much easier to swap.
Although mechanics work daily on suspension, replacing front coil springs is especially hazardous. When placed on the strut, they’ll compress springs using a compressor. If the spring compressor isn’t used correctly or fails, the enormous metal spring can fire off into the technician, causing severe damage.
You need specialist equipment for coil spring replacement! Always take your car to a mechanic.
Don’t get hurt!
Shock Absorber Replacement Cost
Shock absorbers cost a bit more than coil springs, in general. They’re also commonly sold in pairs, so if you’re buying your own components, ensure you purchase the quantity you want.
In most front suspension setups, the shock absorber housing is the MacPherson strut holding the spring and top mount. Therefore, when you buy a front shock absorber, you usually purchase an entire strut.
A quality shock absorber could be $60 to $200, although a figure of around $100 is a reasonable estimate to go on. The mechanic will still need to remove the spring from the old strut to attach it to the new unit. As such, the labor rate will be the same as for replacement coil springs.
Anticipate it to come to $200 to $300 per side.
Rear shock absorbers should be more cost-effective. The parts might cost a comparable amount, but they’re generally simpler to install since there’s no strut involved.
Wishbone/Suspension Arm Replacement Cost
Wishbone (also known as a suspension arm) replacement is an expensive job because it requires the removal of most of the corners of the car.
The suspension arm itself will only come to around $70, but you can expect to add two or three hours of labor to that. In total, costs could readily reach $300 to $400, depending on your vehicle.
What Are The Symptoms Of Needing A Car Suspension Repair?
If you experience any of the following indications while driving, the issue might lie with your suspension. For now, consider “suspension” to be the shocks and springs.
A Rough Ride
Does your car feel a bit more uncomfortable to sit in? Perhaps you’re feeling the bumps in the road more than you used to. Or maybe you’re noticing some extra bouncing as you go over speedbumps or potholes.
The most likely culprit is either a broken spring or shock absorber. A bumpier ride usually means that the spring has snapped or the shock absorber has seized. A bouncier sensation might mean the damper has developed a leak, but the coil spring is still intact.
If you suspect something’s up, take your car to a mechanic. They will put your car up on a ramp to look underneath and identify the problem.
Trust your intuition – it’s better to be safe!
Body Roll
Body roll is what happens when you corner energetically. You can feel the vehicle leaning towards the outside of the turn.
Some cars suffer severely with body roll straight off the production line. Towering, high-riding, and enormous cars are the worst culprits.
However, if your car abruptly develops this sensation, it might be due to a damaged shock absorber or torsion bar.
“Dive” Under Brakes
When you apply the brakes under ordinary circumstances, the car will “dive.” “Dive” refers to the front dipping as the rear rises. It’s all to do with physics and momentum.
Note: if you’re interested, when the front of the car rises and the back drops under acceleration, this is “squat”.
All vehicles experience dive and squat, although most top-notch manufacturers go to great lengths to minimize it.
If you notice your car dipping more than usual when you brake, there may be an issue with the front suspension.
Uneven Tire Wear
The suspension is partly composed of wheels and tires. Anything that breaks in the suspension arm, shocks, or springs will immediately affect the rubber tread.
Problems with the shocks and springs might cause a “cupping” wear pattern. It’s also known as “feathering” or “scalloping” and is when the tread develops dips as it rotates. You’ll probably also feel vibrations through the steering wheel. A new tire will be in order, as well as a replacement suspension component.
If the wishbone breaks, you’re most likely to see irregular wear along one side of your tire. This will throw the tracking out, meaning you’ll need a wheel alignment and a fresh tire.
Bounce Test
Stand over each rear corner of your car and push down. This is part of general checks and should be done monthly as part of routine maintenance.
The body should lower, rise back up, and settle almost immediately. If it keeps bouncing up and down for a second, you’ve got an issue with the suspension.
It likely indicates a faulty shock absorber. Take a look at it if you can. If it has broken, you’ll notice grease dripping down from it.
The bounce test doesn’t really work at the front of the car since the struts are too stiff. Instead, you’ll only be able to identify problems from driving street tests.
What Else Needs Doing When The Suspension Is Repaired?
After the replacement suspension is fitted, you’ll need to have the wheels aligned. New suspension can alter the tracking. Even a few millimeters of change can be enough to put substantial stress on your tires.
The check itself should be complimentary, although some shops might charge. Make sure you understand this before they do it. You should then expect to pay around $100 if it needs adjusting. It’ll be nearer to $150 to $200 if you need a four-wheel alignment.
Although it might feel like a superfluous cost, skipping this step might mean you’re back in a week, red-faced, and needing a new tire or two. Thus, it’s likely to save you money in the long run.
How Much Does Suspension Cost? Conclusion
Suspension is very intricate to work on by yourself at home, even for trained mechanics. It’s quite genuinely hazardous.
Even experts use the specialized spring compressors available in a shop. It’s not worth risking using questionable homemade “equipment.”
Don’t attempt to work on your suspension yourself. If you don’t put it back on correctly, the entire corner of your car could collapse while driving. Although the labor costs might be considerable, think of your personal safety and the vehicle’s operational effectiveness.
In total, you can expect to pay somewhere between $200 and $400 per wheel for vehicular suspension repairs – whatever they may be.
Here’s one last point to leave you with.
Suspension is notoriously frustrating for mechanics to work on. Bolts are always seizing, spring compressors are failing, knuckles are being bloodied, and technicians are cursing the ground on which they stand.
So, the next time you see a mechanic who’s had to replace two shocks and struts, buy them a beverage.
