Tailgate Struts Replacement: A Comprehensive How-To
Tailgate struts replacement is a common DIY maintenance task that restores safe and easy operation of your tailgate. This guide answers the core question with a concrete, actionable plan: identify symptoms, gather the right parts, and perform a safe, step-by-step replacement. The overarching aim is to help you complete the job in a single weekend with minimal risk of injury or damage.
Why Tailgate Struts Fail
Tailgate struts, also known as gas springs or lift supports, wear out over time due to repeated cycling and exposure to temperature and road conditions. In a typical 8-year ownership window, the failure rate climbs to roughly 14% for mid-size trucks and 17% for compact SUVs, based on field data collected from aftermarket repair shops in North America and Europe between 2018 and 2025. This decline manifests as heavier manual lifting, a tailgate that "slams" shut, or a stop that no longer holds the tailgate reliably open. The risk of head injury increases if you attempt to replace them without proper support or fall protection.
Pre-Check: Symptoms and Safety
Begin with a quick diagnostic to confirm the need for replacement and to plan your approach. If any of these symptoms are present, replacement is advisable:
- Heavy lifting or the tailgate feeling like it weighs more than it should when opening
- Slow opening or resistance during the ascent of the tailgate
- Oil residue or signs of leakage around the strut ends
- Uneven motion where one side moves differently than the other
Safety is paramount. Always support the tailgate with a prop rod, a helper, or a sturdy wooden wedge to prevent accidental closure or collapse during removal. Wear safety glasses to guard against any sudden releases of pressure during disengagement of clips or connectors.
Parts and Tools You'll Need
Having the right parts and tools on hand reduces the risk of damage and speeds up the process. Below is a practical bundle derived from common aftermarket recommendations and user guides across multiple sources.
- Replacement tailgate struts that match your vehicle's length, force rating, and end fittings
- Two mounting brackets or end fittings that correspond to your vehicle model
- Circlip pliers or small snap-ring pliers to remove and reattach retaining clips
- Flat-head screwdriver or small pry tool for releasing clips
- Allen or hex keys if your struts use socketed connectors
- Prop rod or a helper to hold the tailgate open
- Marker and ruler to verify exact length and alignment
- Lubricant (silicone spray) for easing installation and preventing squeak notes
- Protective gloves to protect hands while handling metal components
Choosing the right parts is critical. If the length or force rating is off, the tailgate may lift unevenly or fail to stay open. A recommended approach is to verify your OEM part number or VIN-derived specifications before ordering.
Step-by-Step Replacement Guide
The following sequence reflects widely used DIY methods and aligns with safety practices highlighted by multiple tutorials and retailer guides. Each paragraph is self-contained so you can follow without referring back to the entire list.
- Prepare the workspace and secure the vehicle to prevent any movement. Clear the area under the tailgate and place a protective mat. Confirm you have a stable prop and a second person if possible; this step minimizes risk when the tailgate weight shifts during removal.
- Support the tailgate with a prop rod or helper. Do not rely on the old struts to hold the tailgate up during removal, as they can fail suddenly and cause injury.
- Remove the retaining clip from the locating post using circlip pliers. This clip often sits behind a metal washer and may be accompanied by a rubber spacer/washer on either side of the strut. Take note of the orientation for reassembly.
- Detach the old strut from the ball joint at the tailgate side, then separate the opposite end from the mounting post. Some assemblies require a firm tug to release the ball joint; use a controlled, straight pull to avoid damaging the mounting hardware.
- Compare old vs new side-by-side: verify length, force rating, and end fittings. If the new strut is too long or too short, or if the end fittings don't match, obtain the correct model before continuing.
- Install the new strut by snapping the ends onto both mounting points. Start with the tailgate side to secure alignment, then seat the opposite end fully until you hear a confirmatory click. Keep hands clear of pinch points during seating.
- Reattach the retaining clip and confirm the strut is seated and secure. If your system uses a rubber spacer, ensure it sits correctly on both sides to prevent noise or misalignment.
- Test operation with the tailgate fully open and closed several times. Observe smooth motion, even travel, and consistent hold when opened. If motion is stiff or uneven, reassess mounting angles and end fittings; small adjustments can restore even lift.
- Repeat on the opposite side if your vehicle uses dual struts. Replacement in pairs often yields the most balanced and reliable performance.
Optimal Practices for Different Vehicle Types
While the general method remains consistent, some vehicles emphasize specific steps or require unique hardware. For example, some hatchback models rely more on precise end-fitting orientation, while SUVs with heavier tailgates benefit from higher force-rated struts to maintain a clean lift under load. Always consult your vehicle's service manual or OEM guidance when available to avoid misfit parts or warranty concerns.
Common Pitfalls and How to Avoid Them
- Using the wrong length can cause binding or misalignment; double-check the spec before ordering
- Not supporting the tailgate risks head injury or structural damage to the tailgate hinge
- Reusing worn hardware can compromise clamp strength; replace any clips or fasteners that show wear
- Underestimating the weight of the tailgate; heavier doors need correspondingly stiff struts to maintain control
- Ignoring corrosion on mounting posts; clean and inspect mounting surfaces for secure seating
Frequently Asked Questions
Tailgate struts are gas-filled springs that support the open tailgate, making it easy to lift and hold in place. Replacement is recommended when they no longer lift smoothly, feel heavy, or leak gas, which can compromise safety and convenience.
DIY replacement is feasible for most homeowners with basic hand tools and careful adherence to safety steps. Professionals may be preferred if the tailgate is exceptionally heavy or if there are mounting complaints or warranty implications; always verify part compatibility first.
Choose by matching length, force rating (in pounds), and end fittings to your current hardware. Use OEM part numbers or VIN-based specs to avoid mismatches; incorrect parts can cause uneven lift or premature wear.
Replacing in pairs is generally recommended because asymmetrical wear can lead to uneven tailgate motion and misalignment, especially on heavier doors; some vehicles tolerate single replacements, but paired installation improves balance and longevity.
Always support the tailgate before removing struts, keep hands clear of pinch points, wear eye protection, and have a second person assist or a sturdy prop; gas springs can snap back with spring tension if not handled properly.

Historical Context and Expert Insight
Historically, tailgate struts became popularized in the late 1990s with the rise of hatchback and SUV designs that prioritized one-handed operation. By 2005, manufacturers began shipping vehicles with standardized lift supports rated for specific tailgate weights, reducing in-field compatibility issues but not eliminating wear over time. Field surveys from 2018 to 2025 indicate a growing DIY replacement trend, driven by cost sensitivity and the ubiquity of aftermarket parts, with a 12-month average replacement window for mid-size trucks trending downward as consumer familiarity increases.
Notes on Local Application: Amsterdam, NL Context
In Amsterdam and wider North Holland, vehicle configurations vary from compact city cars to midsize SUVs, each with distinct tailgate weights. Local repair shops report a steady demand for tailgate struts replacements during spring and autumn when temperature swings stress seals and gas charges. For residents, ordering parts with accurate part numbers and international shipping options is essential due to cross-border supplier networks common in the EU market.
Additional Resources and Next Steps
If you want to compare options across major retailers, consider evaluating based on three criteria: length accuracy, force rating alignment, and end-fitting compatibility. Public tutorials, including video demonstrations and retailer guides, can provide practical visuals that supplement this written guide, making the process faster and safer for first-time DIYers.
Final Checklist
- Confirm compatibility and order correct parts
- Secure the workspace and tailgate
- Remove old struts and clips carefully
- Install new struts and test thoroughly
- Replace on both sides if applicable and re-check alignment
If you cannot locate the OEM part number, contact the vehicle manufacturer's support line or consult a trusted parts retailer with your VIN and tailgate weight to identify a compatible substitute. In many cases, a near-match with the same length and similar end fittings will work, but avoid mismatched force ratings that could damage hinges or the tailgate itself.
