Yes. In most cars, replacing hood struts is a doable DIY task with basic tools, provided you follow the correct part specifications and take proper safety precautions.
What hood struts do and when to replace them
Types and compatibility
Hood struts are gas-charged lift supports that hold the hood open and control its movement. They come in varying lengths and end fittings, and some vehicles require specific part numbers to fit correctly. When replacing, confirm the extended length, compressed length, and mounting ends to ensure proper operation. If only one side is worn, some owners replace both sides for balanced lifting and longer overall life, though this isn’t strictly required in every case.
Common symptoms of failing hood struts include a hood that won’t stay open, a slow or jerky lift, or oil or residue around the strut ends. If the hood drops unexpectedly or does not hold position, inspect the struts and hinges and plan for replacement.
Safety considerations and preparation
Replacing hood struts involves working with pressurized springs and a heavy hood, so safety is essential. Follow these precautions before you begin.
- Support the hood securely with a prop rod or have a helper hold it open to prevent it from falling.
- Wear eye protection and gloves to guard against pinch points and sharp edges.
- Work on a stable, level surface in a well-lit area; keep bystanders away.
- Dispose of old struts according to local regulations; many auto parts stores will recycle them.
Before you begin, identify the correct replacement parts for your vehicle by checking the year, make, and model, or by bringing an old strut to the parts counter. Some cars require specific length or end fittings, and installation may differ by design.
DIY replacement steps
Below are typical steps for replacing hood struts on many vehicles. Always consult your service manual or the parts retailer for model-specific instructions, as designs vary.
- Support the hood with a prop rod or have a helper hold it open to prevent sudden movement.
- Secure the hood so the old strut can be removed without the hood tipping or snapping back.
- Locate the two struts at the sides of the hood near the hinges and identify the mounting ends (ball socket or stud).
- Detach the end fittings from the mounting points. Some ends use clips or bolts; follow your vehicle’s specific method. Use the appropriate tool and avoid applying excessive force.
- Remove the old strut by disengaging both ends. If necessary, carefully release any clip that holds the end in place while keeping hands clear of the ends.
- Compare the new strut’s length, stroke, and end fittings with the old one to ensure compatibility. Install with the correct orientation—some struts are direction-specific and should be installed so the piston faces the proper travel path.
- Attach the new strut at the upper hinge first, then secure the lower end. Some designs require slight compression of the strut during installation; follow the product instructions. Ensure both ends are seated securely.
- Gently lower the hood to test the lift. The hood should rise smoothly and be held in the open position without supports. If you hear hissing or suspect a leak, stop and recheck the fit.
- Open and close the hood several times to verify balanced operation on both sides. If the hood seems uneven or does not stay open evenly, inspect mounting points and consider replacing both struts for balance.
Important: If the hood does not stay open after installation or you notice leakage, stop and consult a professional. Do not operate a vehicle with a compromised lift system.
Tools and parts you'll need
Collect these items before starting to minimize interruptions.
- Replacement hood struts compatible with your vehicle (check make, model, and year).
- Basic hand tools such as a small flat-head screwdriver, pliers, and possibly a ratchet set for end fittings.
- Safety gear: eye protection and gloves.
- A helper to hold the hood open or a secondary prop rod for safety.
- Rags or cleaner to wipe hinge areas and inspect for rust or wear.
Tip: replacing both struts on the same side or on both sides can improve balance and longevity, even if only one appears worn. Also inspect hinges and mounting points for rust or excessive wear and address those issues as needed.
When to seek professional help
DIY replacement suits most vehicles, but certain situations warrant a professional's touch.
- The hood is unusually heavy or you lack a second person to assist safely.
- There is significant rust, corrosion, or damage around the hinges or strut mounts.
- Your vehicle uses a non-standard or specialty hood mechanism or mounting ends that are difficult to source.
- You’re unsure about part compatibility or feel uncomfortable performing the replacement.
Professional technicians can also inspect hood hinges and overall alignment to ensure the lift system operates safely and correctly, potentially saving time and preventing injury.
Summary
Replacing hood struts is generally a straightforward DIY task for many vehicles, requiring only common tools and proper parts. Confirm compatibility, support the hood during work, and follow model-specific guidance. If you encounter rust, leaks, or misalignment, or if you’re unsure about the process, consulting a professional helps ensure a safely functioning hood lift system and reduces the risk of injury.
Final notes
Always consult your owner’s manual and the parts retailer for model-specific installation details. With careful preparation and proper parts, many drivers can successfully replace hood struts themselves and extend the life of their vehicle’s hood mechanism.
