Replacing rv awning struts is a fundamental maintenance task that significantly extends the lifespan of your outdoor living space. These slender hydraulic components are the unsung heroes of your awning, using compressed gas to counteract the weight of the fabric and deploy it smoothly. Over time, the seals inside these struts degrade, causing the arm to lose its spring and eventually collapse, which can leave your canvas hanging limply or refuse to deploy at all.
While the prospect of tackling this repair might seem daunting, the process is straightforward with the right preparation and tools. Engaging in this maintenance not only saves you the cost of professional labor but also ensures you understand the integrity of your equipment. This guide walks you through the precise steps to safely replace rv awning struts, emphasizing safety protocols and the correct hardware selection to ensure your next adventure under the stars is comfortable and secure.
Understanding the Mechanism and Safety First
Before you begin the physical work, it is essential to understand exactly what you are dealing with. An awning strut is essentially a sealed metal tube containing nitrogen gas that provides the necessary tension to hold the fabric taut. When these fail, the immediate risk is not just a saggy appearance; a completely broken strut can cause the awning to fall unexpectedly, potentially causing damage to the RV or injury to someone standing below.
Therefore, safety is the absolute priority. You should always perform this maintenance on a level, solid surface with the RV securely parked and the parking brake engaged. Furthermore, the wheel chocks are non-negotiable. Because you will be lowering the awning arm to its full extended position to relieve tension, never work on an awning that is partially deployed or wind-assisted. Ensure the fabric is fully retracted and the mechanism is at rest before you climb a ladder.
Gathering the Right Tools and Hardware
Preparation is the difference between a frustrating afternoon and a satisfying repair. You will need a specific set of tools to match the typical hex-head fittings found on most modern RV awnings. While the exact size varies by manufacturer, a standard set of imperial or metric socket wrenches is usually required.
Additionally, you must source the correct replacement hardware. RV struts are sold by specific measurements, which include the total length of the rod and the thread length. It is critical to bring the old strut to the store or verify the model number online to ensure you purchase an exact match. Using a strut that is too short will not provide adequate support, while one that is too long will not fit into the mounting brackets and could jam the mechanism.
| Specification | Description |
|---|---|
| Overall Length | The total distance from the center of the male end to the center of the female end. |
| Rod Diameter | The thickness of the metal rod, usually ranging from 16mm to 25mm. |
| Thread Type | The thread specification (e.g., 1/2" NPT) that must match the male and female fittings. |
Step-by-Step Replacement Procedure
With the area secured and the correct new struts in hand, you can begin the replacement. The typical procedure involves accessing the bracket on the underside of the awning arm where the strut connects. You will usually need to loosen a vertical bolt or pin that holds the bracket in place, which allows you to swing the arm down to a horizontal work position.
Once the arm is secured in a down position, locate the spring-loaded retaining clip or the bolt that locks the piston end of the strut into the bracket. You will need to compress the old strut slightly to relieve the gas pressure and remove the mounting hardware. Carefully extract the old unit and immediately position the new strut into the bracket, reversing the removal steps. Ensure the piston end is fully seated in the bracket before tightening the retaining hardware to the manufacturer's specified torque.
Inspecting the Bracket and Mounting Hardware
One of the most common mistakes during replacement is assuming the bracket and bolts are still in good condition after years of stress. As you remove the old strut, take a moment to inspect the metal bracket for cracks or bending. Replacing a failed bracket mid-deployment is a dangerous scenario you want to avoid.
It is highly recommended to replace the mounting bolts and washers during this process. Stainless steel hardware is resistant to the elements and less likely to seize or snap compared to older galvanized steel. Apply a high-quality marine-grade lubricant to the threads and pivot points of the bracket to ensure smooth operation and protect the metal from rust and corrosion moving forward.
Reassembly and Testing
With the new struts installed and the hardware secured, it is time to return the awning to its operational configuration. Slowly raise the awning arm back to its travel path, listening for any unusual noises that might indicate misalignment or binding. If the arm moves smoothly, you have successfully completed the replacement.
Finally, conduct a thorough test in a controlled environment. Deploy the awning fully and engage the locking mechanism. Walk along the length of the awning to check for any soft spots or unevenness. The fabric should feel tight and the arm should remain securely in place without drifting downward. This test ensures the gas struts are providing the correct amount of lift and that your investment is protected against the elements.
