How Long Does It Take to Replace Struts?

How many labor hours does it take to replace struts?

The average labor time to replace struts typically ranges from 1.5 to 3 hours, but this can vary significantly based on factors like vehicle type, strut location, and the condition of existing components. Most shops provide estimates within this window, but drivers should expect variations depending on the specifics of their car. For instance, front-wheel-drive vehicles often take less time than all-wheel-drive models, as accessing struts in the latter may require additional steps to disconnect drivetrain components.

Factors affecting labor time

- Vehicle make and model: Luxury or performance vehicles (e.g., BMW, Audi) may have complex undercarriage designs, adding 30 minutes to an hour to the process.
- Strut location: Replacing rear struts can take longer than front ones, especially if the vehicle requires removing trim panels or exhaust parts.
- Additional repairs: If rusted bolts, damaged control arms, or worn shocks are present, labor hours may increase by 0.5 to 1.5 hours to address these issues.

How shops calculate labor rates

Mechanics typically charge based on hourly labor rates, which average $75–$150 per hour depending on the shop’s location and expertise. For example, replacing both front struts on a compact car like a Honda Civic might take 1.5–2.5 hours, while a truck or SUV could take up to 3–4 hours due to heavier components and larger undercarriage spacing. Always request a detailed estimate that breaks down labor time and costs for unexpected repairs.

When to expect longer labor times

- Rusted or seized parts: Struts with corroded mounting hardware may require additional time to free components without damaging the suspension.
- Specialized tools: Some vehicles (e.g., those with threaded strut bolts) need specialized equipment, which can slightly extend labor duration.
- Alignment adjustments: Post-installation wheel alignments add 0.5–1 hour to the total labor time, as improper alignment can void warranties or cause premature wear.

Drivers should also note that labor estimates rarely include diagnostics for unrelated issues discovered during the replacement process, which could add time and cost.

Are struts easy to replace?

Replacing struts can be challenging for most drivers, as it requires technical expertise and specialized tools. Struts are integral to a vehicle’s suspension and steering systems, and improper installation can lead to safety risks or poor handling. While the process involves removing the old strut and installing a new one, the complexity depends on the vehicle’s design and the technician’s experience. For example, some cars require lifting the vehicle, disassembling suspension components, and recalibrating sensors, which can be time-consuming and technically demanding.

Key steps involved in strut replacement

The process typically includes:
- Removing the wheel and brake components to access the strut assembly.
- Disconnecting suspension parts and electrical sensors attached to the strut.
- Unscrewing the strut from the chassis while avoiding damage to nearby components.
- Installing the new strut and carefully reassembling all parts, ensuring proper alignment and torque specifications.

Factors that affect ease of replacement

Certain factors can make the job more difficult:
- Vehicle-specific designs: Some cars have tightly packed engine compartments or unique strut configurations.
- Rust or corrosion: Older struts may be stuck due to rust, requiring extra effort to remove.
- Calibration needs: Modern vehicles often require sensors to be reset, which may need professional diagnostic tools.

While DIYers with mechanical skills might manage simpler vehicles, most drivers should consider professional installation to ensure safety and compliance with manufacturer guidelines. The time and tools required often make this a job best left to certified technicians.

Do I need an alignment after replacing struts?

After replacing struts, an alignment is strongly recommended to ensure proper vehicle performance and safety. Struts are critical components of the suspension system, and their replacement can shift the position of wheels relative to the vehicle’s axles. Even minor adjustments during strut installation—such as removing or reinstalling components—can disrupt existing alignment settings. A professional alignment ensures wheels are correctly positioned, optimizing contact with the road and preventing long-term damage.

Why alignment matters after strut replacement

Struts work with other suspension parts like control arms and bushings, which may shift during the replacement process. Without an alignment, you might experience:
- Uneven tire wear, leading to premature replacement costs.
- Pulling to one side while driving, reducing control.
- Reduced handling precision, affecting braking and cornering.
A post-replacement alignment corrects these issues by adjusting caster, camber, and toe angles to factory specifications.

When alignment is essential

An alignment is particularly critical if:
- The old struts were severely worn, causing significant misalignment.
- Other suspension components (e.g., control arms, ball joints) were replaced or repaired during the same service.
- The technician notes shifts in wheel positioning after strut installation.
Even if the replacement seems straightforward, alignment ensures all wheels align correctly with the vehicle’s geometry.

Risks of skipping alignment

Skipping alignment after strut replacement can lead to:
- Increased stress on steering and suspension parts.
- Poor fuel efficiency due to tire drag.
- Safety hazards like unstable handling in adverse conditions.
Proper alignment balances performance, longevity, and driver confidence, making it a cost-effective step post-strut replacement.

What is the labor cost to replace struts?

The labor cost to replace struts varies based on several factors, including the vehicle type, complexity of the repair, and the mechanic’s expertise. Struts are critical components of a vehicle’s suspension system, and their replacement often requires precise alignment and calibration. On average, labor rates for strut replacement typically range from $75 to $150 per hour, though this can fluctuate depending on the shop’s location and reputation. Most shops provide an estimate before starting the job, but unexpected complications (like rusted bolts or damaged parts) may extend labor time and increase costs.

Factors Influencing Labor Costs

Labor costs can differ significantly based on:
- Vehicle type: Smaller cars or compact vehicles often take less time to service, while SUVs, trucks, or vehicles with complex suspension systems may require more labor hours.
- Location: Shops in urban areas or high-cost regions may charge higher hourly rates compared to rural or suburban locations.
- Shop expertise: Specialized mechanics or dealerships for luxury brands (e.g., BMW, Mercedes) may charge premium rates due to training and equipment requirements.

Typical Labor Rates and Estimates

Replacing a single strut usually takes 1–2 hours of labor, resulting in a labor cost of $75–$300. Replacing both struts (commonly recommended for even suspension) may take 2–4 hours, leading to a total labor cost of $200–$600. Some shops bundle alignment adjustments into the labor cost, while others charge separately. Always ask for a detailed breakdown to avoid surprises. Luxury or high-performance vehicles may have higher labor costs due to specialized tools or manufacturer-specific procedures.

The process involves removing the old strut assembly, installing new components, and recalibrating the suspension system. In some cases, additional steps like removing wheel wells or engine components can add time and cost. Transparent communication with the mechanic about potential variables ensures clarity and helps manage expectations.
