Does a Toyota Avalon have shocks or struts?

In short, the Avalon uses MacPherson struts in the front and independent rear shocks (not a full rear strut). This means the front suspension relies on a strut assembly, while the rear uses separate shock absorbers for damping.

Understanding the distinction helps when shopping for parts or planning maintenance. The Avalon’s setup is a common arrangement for a large, comfort-focused sedan: a front strut-based system that supports steering and load, paired with a rear suspension that uses dampers to control wheel movement and ride quality.

Front suspension: MacPherson struts

The Avalon’s front suspension employs a MacPherson strut design. In this arrangement, the shock absorber (damper) and coil spring are combined into a single unit mounted to the steering knuckle and the vehicle frame. This compact, economical configuration provides straightforward assembly and is widely used on front-wheel-drive sedans to balance space, weight, and cost.

Rear suspension: independent multi-link with shocks

At the rear, the Avalon uses an independent multi-link suspension with coil springs and separate shock absorbers. This setup allows each rear wheel to respond to road irregularities independently, improving ride comfort and maintaining tire contact with the road through dedicated damping units.

Key components by location:

• Front: MacPherson struts (shock absorber integrated with coil spring)


• Rear: Independent multi-link with coil springs and separate shock absorbers

Conclusion: The Avalon combines front struts with rear shocks. This mixed configuration is common in sedans focused on comfort and stable handling, offering relatively simple front-end maintenance and effective rear damping.

Maintenance considerations: When servicing, expect front strut assemblies to be replaced as a unit, while rear shocks are typically replaced as separate dampers. Regular inspections for leaks, sagging, or unusual bouncing can help keep the ride smooth and handling predictable.

Summary: The Toyota Avalon uses MacPherson struts in the front and an independent rear suspension with shocks. In other words, it has both shocks and struts, depending on the location—fronts are struts; rears are shocks. This configuration supports a comfortable, stable ride typical of full-size sedans.

What is the common issue with Toyota Avalon?

Common problems for the Toyota Avalon include ignition coil failures, especially after 100,000 miles, and leaking valve cover gaskets. Other issues include problems with the automatic transmission, such as rough shifting, and issues with the Evaporative Emission Control System (EVAP) (like a faulty canister or purge valve) which can cause a check engine light. Some model years have also reported specific issues like unintended acceleration and peeling paint.

Engine 

• Ignition Coils: May fail after 100,000 miles, leading to misfires and a check engine light.
• Oil Leaks: Valve cover gaskets are a common source of oil leaks.
• EVAP System: Issues with the EVAP canister or purge control valve can trigger the check engine light.
• Oxygen Sensor: A failed oxygen sensor can cause the check engine light to turn on.
• Sludge Buildup: Can occur with infrequent oil changes and cause engine problems. 

Drivetrain and transmission

• Automatic Transmission: Some owners report the transmission not shifting correctly at higher mileages. 
• Unintended Acceleration: A serious problem reported in some models, particularly the 2014 model year, where the gas pedal may become stuck. 

Other common issues

• Rear Window Sunshade: This feature has been reported to fail and make a grinding noise. 
• Peeling Paint: A problem reported on certain model years, often on the roof and around the sunroof. 
• Infotainment System: Some owners have complained about distorted speakers and issues with the infotainment system.

How do I know if my car has struts or shocks?

The easiest way to find out whether you have shocks or struts or both is by referring to your vehicle's owner's manual. It will typically provide information about the type of suspension system installed in your vehicle.

How long do struts last on a Toyota Avalon?

Bottom Line on Car Struts and Shocks
These components can sometimes last 100,000 miles or more, but replace them when needed to ensure your vehicle remains stable. Timely maintenance can keep your drive comfortable and save you from more costly repairs down the road.

How much does it cost to replace struts on a Toyota Avalon?

The cost to replace the struts on a Toyota Avalon ranges from approximately $450 to over $1,200, depending on whether you're replacing two front struts or all four. The final price depends on parts and labor, with the labor cost often being similar to the parts cost. You can expect to pay around $1,000–$1,200 for a front strut replacement and potentially more for rear struts due to their complexity. 
Cost breakdown

• Parts: Struts can cost under $200 per side for the parts alone, though higher-quality or all-inclusive assemblies will cost more. 
• Labor: Labor can be a significant portion of the total cost, sometimes equaling the cost of the parts themselves. The rear struts are often more labor-intensive and can increase the overall labor cost. 

Factors that influence the cost

• Number of struts: Replacing all four struts will cost more than replacing just the front or rear set. 
• Part quality: The cost will vary based on whether you choose OEM (Original Equipment Manufacturer) or aftermarket parts, and the quality of the aftermarket part. 
• Labor rates: Labor costs vary by region and by shop, so getting quotes from different mechanics is recommended. 
• Model year: Different model years may have varying labor times and part costs. 
• Additional parts: The cost can increase if other suspension components are found to be worn and need replacing at the same time. 

What to expect

• Signs of worn struts: You may notice a bumpy ride, knocking sounds, or uneven tire wear if your struts are failing. 
• Safety: Worn struts can increase your stopping distance, and on wet roads, your risk of skidding. 
• Benefits of replacement: Replacing worn struts will restore your car's original handling and ride quality, improve tire wear, and help prevent further damage to other suspension parts.
