Replacing the shocks or struts is a common maintenance issue that arises out of the need to keep the vehicle safe, stable and comfortable.
The cost can vary widely, usually ringing in at anywhere from $500 to $3000. This price range reflects the varying complexity of different vehicle suspension systems as well as the premium that tends to come with luxury vehicle repairs.
For most widely owned, standard vehicles, setting aside about $1,000 should sufficiently cover the costs of this repair.
Understanding Shocks and Their Distinction from Struts
In the realm of vehicle suspension systems, components like shocks and struts play pivotal roles.
Shocks, also known as shock absorbers, can be used on their own or as part of a strut.
The suspension of a car is an intricate network that includes springs and dampers designed to ensure a smooth ride.
- Springs: They are vital in supporting the vehicle’s weight, maintaining a separation between the wheels and the body, and absorbing road irregularities. Without them, you would experience every imperfection of the road directly.
- Dampers: Both shocks and struts fall into this category. Their essential function is to attenuate the oscillations of the vehicle caused by the springs, providing a controlled and comfortable ride.
Shocks, commonly referred to as dampers, are fluid-filled cylinders that counteract the bouncing by restricting fluid movement through precision-engineered valves. The resistance created by the fluid’s movement tempers the spring’s motion, reducing vehicle bounce.
On the other hand, struts are a composite unit combining the functions of a damper and structural support. They often play a role in the steering mechanism and may include the spring itself within their assembly.
Struts thus serve a dual purpose: they not only dampen movement like shocks do, but they also contribute to the vehicle’s structural integrity and alignment.
A famous type of strut is the MacPherson strut, named after an innovative engineer, Earle S. MacPherson, who revolutionized the design to facilitate more economical car production.
| Shocks (Shock Absorbers) | Struts |
|---|---|
| Non-structural | Structural component |
| Solely dampen motion | Dampen motion and support vehicle weight |
| Not integral to steering | May be part of steering system |
| Simple design with two tubes and fluid | More complex, often integrated with springs |
Recognizing When to Replace Shocks and Struts
If I notice my car performing poorly over bumps or hear strange noises coming from the corners, it might be time to inspect the suspension system. Here’s what I look for:
- Bouncing: Excessive movement over speed bumps signifies worn dampers.
- Noises: A distinctive banging sound when hitting a pothole could mean damage.
- Handling: If my steering feels loose or unresponsive, my shocks or struts may need attention.
- Braking: A tendency to dip forward under hard braking indicates potential strut issues.
- Turning: Feeling the car sway or seem ‘tippy’ while cornering suggests worn components.
- Vibration: Unusual vibration in the steering wheel might be due to failing shocks.
- Tires: Uneven tire wear can also be a symptom of suspension problems.
Ride comfort and handling rely on a well-maintained suspension. If these issues sound familiar, it’s best to have my vehicle checked to maintain a safe and comfortable driving experience.
Reasons Behind Shocks and Struts Deterioration
Shocks and struts are integral to a vehicle’s suspension system, and their failure can significantly impact tire wear and overall maintenance. I find that several factors contribute to their degradation:
- Wear from Prolonged Use: Regular exposure to corrosive substances, like road salt, hastens their deterioration.
- Impact Damage: A severe jolt from obstacles like large potholes can internally harm shocks and struts, leading to leakage of the dampening fluid and a shortened lifespan.
To maintain a vehicle’s suspension system and prevent uneven tire wear, I suggest routine inspections and prompt replacements of these components when necessary.
Possibility of Repairing Suspension Components
Shocks are always replaced rather than repaired. However, when it comes to struts, there are instances where only the internal damper could need replacing, not the entire assembly.
This is feasible with insert kits designed for such a purpose, provided that the rest of the strut components are in good condition.
Choosing between a full assembly replacement or just the damper part depends on various factors such as age, wear, or specific damage. Trust a qualified mechanic to make an informed decision on the best course of action.
Replacing Single Shocks or Struts: Is It Advisable?
When it comes to maintaining your vehicle’s suspension system, mechanics usually recommend replacing shocks and struts in pairs—this means both the front set or both the rear set. However, if you have a new car and encounter an issue with one shock or strut, due to a defect or damage from an incident, a mechanic might suggest you replace just the faulty one. This exception mostly applies when the car is still quite new.
Is It Safe to Drive With a Compromised Shock or Strut?
Driving with a compromised shock or strut is unsafe and can seriously affect your vehicle’s handling and braking performance. Worn or damaged shocks or struts diminish handling, making it difficult to control the vehicle during sudden maneuvers or on uneven roads.
This issue also extends to braking, as faulty shocks or struts increase the vehicle’s stopping distance, especially under heavy braking. The compromised suspension can lead to uneven tire wear and increased strain on other vehicle components, further affecting safety and potentially leading to tire blowouts.
In wet conditions, the risk is heightened as worn shocks or struts can cause the vehicle to hydroplane more easily, losing contact with the road surface. Additionally, while not a direct safety concern, the reduced ride comfort from failing suspension parts can lead to driver distraction and fatigue. Given these risks, it’s crucial to have any issues with shocks or struts inspected and repaired by a professional mechanic promptly to ensure safe driving conditions.
Necessity of Vehicle Alignment Post Shock or Strut Work
When replacing front struts, I always recommend a wheel alignment. These components are integral to tire performance and handling.
In the case of older vehicles, realignment post shock replacement isn’t mandatory unless the shocks suffered damage due to impacts like potholes, curb strikes, or vehicular accidents. In such events, aligning the vehicle is a definite must to ensure proper tire function and road safety.
Can I Replace My Own Shocks and Struts?
Absolutely, many individuals with basic car repair skills take on the task of replacing shocks. Nevertheless, you’ll need certain special tools to compress the springs, which is a critical safety measure.
If you’re not confident in your abilities, it’s wiser to consult a professional. Replacing struts is a more complex undertaking, and regardless of who does the job, an alignment will be necessary afterward. Due to these complexities, I typically recommend that strut replacement be left to a professional service center.
How Much Do Shocks and Struts Cost to Replace?
Replacing shocks on standard vehicles can be quite affordable, ranging from $500 to $1,000. This price assumes that the shock mounts are in good condition, without damage or corrosion.
For struts, which serve as a structural component of the vehicle and are integral to steering, particularly the front struts, the replacement costs are higher due to their complex design and dual function. Expect front strut replacements, including a wheel alignment, to begin at over $1,000. Luxury car models may incur costs significantly higher, sometimes more than double.
Should you opt for a repair at a dealership using OEM parts, the price can increase by approximately 25% to 50% compared to using aftermarket parts at a local service shop. The choice of brand and whether additional services are needed can also impact the final cost.
