How to Find and Replace a Used Car Strut Assembly

Signs Your Car Needs Strut Assembly Replacement

Identifying a failing strut assembly early can save you money and prevent more serious suspension damage. Worn struts don’t just affect ride comfort; they compromise braking distance and steering control, making them a critical safety component.

• Bouncy ride – Your vehicle continues to bounce after hitting bumps or dips excessively when braking
• Nose diving – Sharp forward tilting during braking indicates compromised damping
• Uneven tire wear – Look for “cupping” or feathering patterns on tire treads
• Fluid leaks – Oily residue on the strut body signals blown seals
• Excessive vibrations – Steering wheel or chassis vibrations, especially at higher speeds
• Poor handling – Drifting, swaying in turns, or general instability

These symptoms indicate diminished strut performance and necessitate immediate inspection. When shopping for replacement parts, consider exploring when to buy used auto parts to make an informed decision about your repair options.

Finding Quality Used Strut Assemblies at Salvage Yards

Sourcing used strut assemblies from reputable salvage yards can provide significant cost savings compared to new parts. The key is knowing where to look and what to inspect before making your purchase.

Locating the Right Donor Vehicle

Start by identifying vehicles that match your car’s specifications. Visit LKQ Pick Your Part locations or other salvage yards to find compatible donor cars. Ensure the donor vehicle is the same make, model, and year, or verify cross-compatibility through parts catalogs.

Inspection Point	What to Look For	Red Flags
Leaks	Clean, dry strut body	Oil or fluid residue
Corrosion	Minor surface rust acceptable	Structural rust or deep pitting
Spring Condition	Properly seated, crack-free coils	Cracked or sagging springs
Mounts/Bushings	Intact rubber components	Cracked or deteriorated bushings

Essential Tools for Strut Assembly Replacement

Having the right tools is crucial for safely removing and installing strut assemblies. Never attempt this repair without proper equipment, especially spring compressor tools.

• Jack and jack stands – For safe vehicle lifting and support
• Socket set and ratchets – Various sizes (typically 14mm, 17mm, 19mm)
• Breaker bar – For loosening stubborn bolts
• Spring compressor tool – ESSENTIAL for safe spring handling
• Torque wrench – To meet manufacturer specifications
• Penetrating oil – WD-40 or similar for rusty bolts
• Pry bar and hammer – For component separation
• Safety equipment – Gloves, safety glasses, work clothes

Professional mechanics recommend having specific tools when working at junkyards to ensure safe and efficient part removal.

Step-by-Step Removal Process from Donor Vehicle

Removing strut assemblies from salvage vehicles requires careful technique to avoid damaging the parts or injuring yourself. Follow this detailed process for safe extraction.

Safety Preparation

• Ensure the vehicle is on level ground with wheel chocks
• Use proper jack stands – never rely solely on a jack
• Take photos before disassembly for reference
• Remove the wheel to expose the strut assembly

Component Disconnection

Start by carefully disconnecting all attached components to prevent damage during removal:

• Brake line clips – Remove carefully to avoid stretching lines
• ABS sensor wires – Unclip from strut mounting points
• Sway bar end links – Use proper wrenches to avoid rounding bolts
• Tie rod ends – Separate from steering knuckle if necessary

“Never attempt to compress springs or disassemble struts without a proper spring compressor tool due to risk of serious injury. The compressed spring can eject violently and cause severe trauma.”

For visual guidance on this process, watch detailed tutorials like this comprehensive strut replacement video that demonstrates proper safety techniques.

Strut Removal Sequence

• Remove lower strut bolts – Typically 14-17mm pinch bolts
• Support the steering knuckle – Use jack stand to prevent dropping
• Access upper mount nuts – Usually located in engine bay or trunk
• Leave center nut intact – Do not remove spring compression nut
• Extract the assembly – Carefully maneuver out of wheel well

Professional Installation Process

Installing your used strut assembly requires reversing the removal process with attention to proper torque specifications and alignment. This step-by-step guide from experienced DIY mechanics provides detailed instructions for various vehicle types.

Installation Steps

• Compare assemblies – Verify used part matches your old strut
• Insert from top – Start with upper mount in strut tower
• Align bottom connections – Connect to steering knuckle or control arm
• Finger-tighten initially – Allow for adjustment during assembly
• Reconnect all components – Brake lines, sensors, sway bar links
• Final torque with weight on – Lower vehicle before final tightening

Component	Typical Torque Spec	Note
Upper mount nuts	25-30 ft-lbs	Final tighten with vehicle down
Lower strut bolts	70-85 ft-lbs	Most critical for safety
Sway bar links	35-45 ft-lbs	Don’t over-tighten bushings

Quality Inspection and Testing

After installation, thorough inspection ensures your strut assembly replacement was successful and safe. Check out AutoZone’s comprehensive strut replacement guide for additional safety checkpoints.

Post-Installation Checklist

• Brake line clearance – Ensure no rubbing or pinching
• Sensor wire routing – Check ABS wires are properly secured
• Steering movement – Verify full lock-to-lock operation
• Visual inspection – Look for proper alignment of all components
• Test drive – Start with low speeds to check for noises

Understanding OEM suspension parts from salvage yards can help you identify quality components and avoid problematic installations.

Cost Savings and Expert Tips

Using used strut assemblies can save significant money compared to new parts. Professional repair shops typically charge $300-700 for front strut replacement including parts and labor, making DIY installation with salvage parts an attractive option.

Money-Saving Strategies

• Replace in pairs – Maintain balance and handling consistency
• Complete assemblies – Avoid dangerous spring disassembly
• Timing your visit – Learn about the best days to visit junkyards
• Bulk purchasing – Many yards offer discounts for multiple parts
• Warranty options – Some salvage yards provide short-term warranties

For additional savings opportunities, explore Pick-A-Part deals and discount days that can reduce your parts costs even further.

Professional Recommendations

• Use thread locker on critical fasteners
• Apply anti-seize compound to prevent future corrosion
• Consider professional alignment after installation
• Keep documentation for warranty purposes

Community forums like Edmunds discussion boards provide valuable insights from experienced DIYers who have successfully completed similar projects.

Safety Considerations and Best Practices

Working with suspension components involves serious safety considerations. The automotive industry continues to emphasize the importance of proper techniques, especially when dealing with compressed springs and heavy assemblies.

• Never skip spring compressors – Uncontrolled spring release can cause fatal injuries
• Use proper lifting techniques – Strut assemblies are heavier than they appear
• Wear safety equipment – Eye protection and gloves are essential
• Work on level surfaces – Ensure vehicle stability throughout the process
• Have backup support – Consider having an experienced helper present

Alternative Solutions and Related Repairs

While replacing complete strut assemblies is often the best approach, understanding related suspension repairs can help you make informed decisions about your vehicle’s needs.

Related Suspension Components

Consider inspecting and potentially replacing these related components during your strut replacement:

• Control arms and bushings
• Brake components that may have been affected by worn struts
• Sway bar links and bushings
• Ball joints and tie rod ends

When to Consider Professional Help

Some situations warrant professional assistance:

• Complex electronic damping systems
• Vehicles with integrated steering systems
• When specialized alignment equipment is needed
• If you encounter unexpected complications during removal

Research questions to ask before choosing an auto repair shop if you decide professional installation is necessary.

Environmental Impact and Recycling Benefits

Choosing used auto parts contributes significantly to environmental conservation. The automotive recycling industry prevents millions of tons of materials from entering landfills annually while providing affordable repair options.
