Tailgate gas struts are crucial components that ensure the safe and effortless operation of your vehicle’s tailgate. They are designed to support the weight of the tailgate, allowing it to open smoothly and remain securely in the open position. Over time, these struts can lose their pressure or mechanical integrity, leading to a tailgate that’s difficult to lift, prone to sudden drops, or simply won’t stay up. Addressing this issue promptly with a tailgate gas struts replacement is essential for both convenience and safety.
Understanding Tailgate Gas Struts and Their Importance
Before diving into the replacement process, it’s helpful to understand what tailgate gas struts are and why they are so vital. These specialized hydraulic cylinders contain pressurized gas and oil, working together to provide controlled resistance and support.
What They Do for Your Tailgate
The primary function of tailgate gas struts is to counteract the weight of the tailgate, making it feel lighter and easier to lift. They also provide a dampening effect, preventing the tailgate from slamming shut and reducing wear on hinges and other components. When functioning correctly, they hold the tailgate firmly in the open position, allowing for safe loading and unloading.
Signs of Failing Tailgate Gas Struts
Identifying failing tailgate gas struts early can prevent potential injuries or damage. Look out for these common symptoms:
Difficulty Lifting: You might notice the tailgate feels significantly heavier than usual.
Sudden Drops: The tailgate may not stay open on its own, or it might fall unexpectedly after being lifted.
Squeaking or Groaning Noises: Worn internal components can cause audible signs of distress.
Loss of Support: The tailgate might only stay partially open, or it may require manual propping.
Visible Damage: Leaks around the strut body or bent shafts indicate a need for tailgate gas struts replacement.
Gathering Your Tools and Supplies for Tailgate Gas Struts Replacement
Having the right tools and replacement parts on hand will make the tailgate gas struts replacement process much smoother and safer. Preparation is key to a successful DIY repair.
Essential Tools You’ll Need
Most tailgate gas struts replacement jobs require only basic hand tools. Ensure you have these items before you begin:
Flathead Screwdriver or Pry Tool: Often used to release retaining clips on the strut ends.
Small Pick Tool (optional): Can be helpful for stubborn clips.
Prop Rod or Sturdy Support: CRITICAL for safely holding the tailgate open during the process. A broom handle or a dedicated prop rod works well.
Safety Glasses: Always protect your eyes when working on vehicles.
Work Gloves: To protect your hands.
Clean Rag: For wiping away dirt or grease.
Choosing the Right Replacement Tailgate Gas Struts
Selecting the correct replacement tailgate gas struts is paramount. Struts are vehicle-specific, varying in length, pressure, and mounting style. Always verify compatibility.
Vehicle Information: Know your vehicle’s make, model, year, and body style.
Part Numbers: If possible, check the part number on your existing struts for an exact match.
OEM vs. Aftermarket: Both options are available. OEM (Original Equipment Manufacturer) parts ensure an exact fit, while quality aftermarket options can offer cost savings.
Purchase a Pair: It’s highly recommended to replace both tailgate gas struts simultaneously, even if only one appears faulty. This ensures balanced support and extends the lifespan of the repair.
Step-by-Step Tailgate Gas Struts Replacement Guide
Follow these steps carefully to perform a safe and effective tailgate gas struts replacement.
Step 1: Prepare for Safety
Safety is paramount. Park your vehicle on a flat, level surface and engage the parking brake. Open the tailgate fully and use your prop rod or a sturdy helper to securely hold it in the open position. This is crucial to prevent the tailgate from falling during the strut removal.
Step 2: Locate and Inspect the Old Struts
Identify the existing tailgate gas struts. They are typically located on either side of the tailgate, connecting the tailgate itself to the vehicle’s body. Take a moment to observe how they are mounted, noting the position of the clips or bolts.
Step 3: Remove One Old Tailgate Gas Strut
Work on one strut at a time to maintain some stability for the tailgate. Locate the retaining clips at each end of the strut. Using a flathead screwdriver or pry tool, carefully lift or pry the clip away from the ball joint. Once the clip is disengaged, the strut end should pop off the ball stud. Repeat for the other end of the strut. Be prepared for a slight shift in tailgate weight, even with the prop rod in place.
Step 4: Install the New Tailgate Gas Strut
Take your new tailgate gas strut. Most new struts come with the retaining clips already in a ready-to-install position. Align one end of the new strut with its corresponding ball stud on the tailgate or vehicle body. Push firmly until it snaps into place. You should hear a click, indicating it’s securely seated. Repeat this for the other end of the strut. Do not force it; if it doesn’t align easily, slightly adjust the tailgate’s position if necessary.
Step 5: Repeat for the Second Tailgate Gas Strut
Once the first new strut is installed, you can remove the prop rod and move it to support the tailgate while you replace the second strut. Follow the exact same procedure as outlined in Step 3 and Step 4 for the remaining old and new tailgate gas strut.
Step 6: Test the New Tailgate Gas Struts
With both new tailgate gas struts installed, carefully remove the prop rod. Slowly close and open the tailgate several times. It should now lift smoothly, hold securely in the open position, and close with controlled resistance. Ensure there are no strange noises or excessive play.
Tips for a Smooth Tailgate Gas Struts Replacement
Keep these additional tips in mind to ensure a hassle-free tailgate gas struts replacement:
Clean Mounting Points: Before installing new struts, wipe down the ball studs to remove any dirt or old grease.
Lubrication (Optional): A small amount of dielectric grease on the ball studs can aid in installation and prevent future sticking.
Read Instructions: Always review any specific installation instructions provided with your new tailgate gas struts, as designs can vary slightly.
Two-Person Job: While possible alone, having a helper to hold the tailgate steady can significantly ease the process, especially if the tailgate is heavy.
Conclusion: Enjoy Your Restored Tailgate Functionality
Replacing your tailgate gas struts is a straightforward maintenance task that can dramatically improve the usability and safety of your vehicle. By following this detailed guide, you can confidently perform the tailgate gas struts replacement yourself, saving money and gaining a valuable sense of accomplishment.
