What Are Rear Hatch Struts and Why They Fail
Replacing rear hatch struts yourself is a straightforward process that restores your vehicle's liftgate support. This guide details the steps to safely remove old struts and install new ones, ensuring your hatch stays open reliably.
- Worn struts can no longer hold the hatch open.
- Struts are gas-filled cylinders providing lifting assistance.
- Common failure points include leaks and loss of gas pressure.
- Replacement is crucial for safety and preventing damage.
Understanding Hatch Strut Functionality
Rear hatch struts, often called lift supports or gas springs, are specialized pneumatic cylinders. They contain compressed gas (typically nitrogen) and a small amount of hydraulic fluid. When you open the hatch, the gas expands, assisting the lifting motion and holding the hatch securely in the open position. This mechanism prevents the heavy hatch from slamming shut unexpectedly, which is vital for safety.
Think of them as gas-charged shock absorbers for your tailgate. The internal seal is critical; once compromised, the gas escapes, and the strut loses its lifting power. This is why a failing strut can no longer hold the hatch up, leaving it sagging or closing on its own.
Our analysis indicates that exposure to extreme temperatures and constant stress from opening and closing are primary factors in their eventual degradation. Unlike more complex components like a mini 14 accu strut or a full strut turkey mount, these are designed for consistent, predictable movement.
It is imperative to acknowledge that a malfunctioning hatch strut is not merely an inconvenience; it poses a significant safety risk. The hatch can fall unexpectedly, potentially causing injury to anyone standing beneath it or damage to items being loaded or unloaded.
Common Signs of Failing Struts
You'll notice several clear indicators when your rear hatch struts are nearing the end of their service life. The most obvious sign is the hatch not staying open on its own. It might droop slowly or drop suddenly, requiring you to prop it up manually. Another symptom is difficulty lifting the hatch; you'll feel significantly more resistance than usual.
Sometimes, you might observe visible signs of wear on the strut itself, such as oil or grease leaking from the cylinder shaft or the seal. The speed at which the hatch opens might also change; it could open much slower than it used to, or slam open too quickly without proper damping. Understanding these signs is fundamental.
This mechanism is critical for user safety and vehicle accessibility. Ignoring these symptoms can lead to further damage or personal injury.

Essential Tools and Preparation for Strut Replacement
What You'll Need to Get Started
Before you begin, gather the necessary tools and safety equipment to ensure a smooth and secure replacement process. Having everything ready will prevent interruptions and potential hazards. You’ll need a set of new rear hatch struts specifically designed for your vehicle's make, model, and year. Always verify part compatibility.
Essential tools include a socket set or wrenches (often 10mm, 12mm, or 13mm), a flathead screwdriver, safety glasses, work gloves, and potentially a second person to help stabilize the hatch. A helper is highly recommended, as the hatch can be heavy and awkward to manage solo.
You might also need a ladder if your vehicle's hatch sits very high when open. For securing the hatch temporarily, a sturdy prop rod, a broom handle, or even a length of strong rope can be used as a safety backup while you disconnect the old struts. This is a proactive measure against unexpected drops.
Safety First: Securing the Hatch
This is the most critical step before any disassembly begins. The rear hatch is heavy and balanced on its hinges. If not properly supported, it can fall unexpectedly and cause serious injury or damage. Never rely solely on the failing struts to hold the hatch up.
Secure the hatch firmly in the fully open position. Use your prop rod, helper, or rope to brace the hatch against the vehicle body or roof. Ensure the support is stable and will not slip. If working alone, a robust prop rod wedged securely is your best bet. This principle applies whether you’re dealing with standard liftgate struts or specialized units like lesjofors gas struts rear specifications.
Failing to secure the hatch is a common mistake that leads to accidents. Such precision is paramount for DIY tasks involving heavy lifting components.
When working on your vehicle, always consider the context of similar heavy-duty applications, like installing a garage door reinforcement strut or using universal strut clamps for custom projects. The need for secure bracing remains constant.
Step-by-Step Guide to Replacing Your Rear Hatch Struts
Removing the Old Struts
With the hatch securely supported and tools at hand, you can begin removing the old struts. Each strut is typically attached at two points: one on the vehicle body and one on the hatch itself. You'll usually find a ball stud fitting secured by a metal clip or a small bolt.
Start by identifying the attachment points. Use a flathead screwdriver to carefully pry away the retaining clip or loosen the bolt holding the strut's ball fitting to the stud. Be gentle; these clips can be brittle. Once one end is detached, repeat for the other end of the same strut. If the strut is still under pressure, it might want to extend or retract slightly; be prepared to control its movement.
Sometimes, the attachment point is a bracket instead of a ball stud. In such cases, you might need to loosen or remove bolts holding the bracket. Always work methodically, one strut at a time if possible, to maintain some balance.
It is imperative to acknowledge that the force exerted by a strut, even when failing, should not be underestimated. Proceed with caution.
Installing the New Struts
Now, take your new rear hatch strut. Align one end with its corresponding attachment point on either the hatch or the vehicle body. Often, you can simply push the ball fitting onto the stud until it clicks into place, or re-secure it with the clip or bolt you removed. If a clip was used, ensure it's fully seated to prevent the strut from popping off.
Attach the other end of the new strut to its mating point. Once both ends are connected, gently test the strut's connection by trying to move it manually. It should feel secure and resist movement. With the first new strut installed, repeat the process for the second strut on the opposite side of the hatch, or if you’re replacing them in pairs as recommended.
The primary consideration involves ensuring both new struts are installed in the correct orientation and securely fastened. Misaligned strut angle bracket attachments can lead to premature wear or failure.
Pro Tip: Before fully tightening any bolts or re-seating clips, gently push and pull on the new strut to ensure it seats correctly onto the stud. A firm, positive engagement is key.
Final Checks and Testing
Once both new struts are installed, remove any temporary supports or props from the hatch. Slowly and carefully lower the hatch, feeling for smooth operation. Then, raise it again. The new struts should now effortlessly lift the hatch and hold it steady at its fully open position without any sag. Cycle the hatch open and closed a few times to ensure smooth operation and that both struts are working in unison.
If the hatch operates smoothly and stays put, you have successfully replaced your rear hatch struts. This is a simple yet effective way to maintain your vehicle's functionality and ensure safety during use.
