If you've noticed your patio shade isn't staying up like it used to, it's probably time for an rv awning gas strut replacement before the whole thing becomes a safety hazard. There is nothing quite as frustrating as setting up camp, reaching for that extension button, and watching your awning slowly drift downward or, worse, refuse to stay tensioned against a light breeze. Those little gas-filled cylinders do a lot of heavy lifting, and like anything else on a rig that bounces down the highway, they eventually wear out.
Why Those Struts Give Up the Ghost
Most of the time, we don't even think about the gas struts until they stop working. These components are essentially pressurized shocks that provide the "muscle" to hold the heavy fabric and metal arms of your awning in place. Inside that metal tube is a pressurized gas (usually nitrogen) and a bit of oil for lubrication.
Over time, the seals inside the strut start to perish. This happens faster if you live in a climate with extreme temperature swings. Heat causes the gas to expand and put pressure on the seals, while cold can make the rubber brittle. Eventually, a tiny bit of gas leaks out. Once that happens, the strut loses its "push," and you're left with an awning that feels like it's gained fifty pounds overnight. If you see oily residue leaking down the shaft of the strut, that's a dead giveaway that the internal seal has failed and you're overdue for a swap.
Getting the Right Parts
Before you go ordering anything, you need to realize that not all struts are created equal. You can't just grab a random set and hope for the best. If the strut is too weak, the awning will still sag. If it's too strong, you might actually bend the awning arms or strip the mounting hardware because the motor can't overcome the pressure to close it.
Take a look at your old strut. There should be a label or an engraving on the cylinder. You're looking for two main things: the length (usually measured from the center of one mounting hole to the other when fully extended) and the force rating. The force is typically measured in Newtons (N) or pounds (lbs). For example, you might see "120N" or "60 lbs" printed on the side. If the text has rubbed off, your best bet is to look up your awning's specific model number. Common brands like Dometic, Carefree of Colorado, and Solera all have specific specs for their hardware.
Tools You'll Actually Need
The good news is that an rv awning gas strut replacement isn't a job that requires a massive rolling toolbox. You can usually get this done with just a few basics: * A small flat-head screwdriver (for popping the retaining clips). * A pair of needle-nose pliers. * A sturdy ladder. * A helper (this is a big one—don't try to hold a heavy awning arm and swap a strut at the same time). * A 2x4 piece of wood or a telescoping pole to prop the awning arm open.
The Step-by-Step Process
First things first: safety. An awning under tension can be dangerous. If that arm snaps shut while your fingers are in the way, you're going to have a very bad weekend.
1. Secure the Awning Extend your awning fully. Once it's out, use your 2x4 or a support pole to prop up the outer rafter. You want to take the weight off the strut you're replacing. If the strut is under tension, it will be nearly impossible to pull off, and it might fly out with surprising force once it's released.
2. Remove the Retaining Clips Most RV struts use a "ball and socket" joint. There's a tiny metal spring clip wrapped around the head of the strut. Take your small flat-head screwdriver and gently pry that clip up. You don't usually need to take it all the way off—just enough to loosen its grip on the ball stud. Once the clip is loose, the strut should pop right off the ball. Do this for both the top and the bottom.
3. Check the Ball Studs While the old strut is off, take a second to look at the mounting points. If the ball studs are rusted, wiggly, or caked in grit, clean them up. A little bit of silicone grease on the ball can help the new strut pivot smoothly and prevent premature wear on the new socket.
4. Installing the New Strut This is the satisfying part. Most new struts are designed to just "click" into place. You shouldn't even need the screwdriver for this. Align the socket with the ball stud and give it a firm push with the palm of your hand. You'll hear a distinct click when the internal spring captures the ball.
Pro tip: Make sure you install the strut in the same orientation as the old one. Usually, this means the thicker "body" of the strut is at the top, and the thinner "rod" points down. This allows the internal oil to keep the seals lubricated every time the awning moves.
Why "Close Enough" Isn't Good Enough
I've seen folks try to use automotive hatch struts for an rv awning gas strut replacement because they found them cheaper at a local parts store. I strongly suggest you don't do that. Automotive struts are tuned for the weight of a car's trunk or hood, which has a very different movement arc than an RV awning. Awning struts are specifically valved to handle wind gusts and the slow, steady draw of a 12V motor. Using the wrong part can lead to a "buckling" effect where the arm doesn't fold flat, potentially causing your awning to catch the wind while you're driving down the interstate. That's a recipe for a very expensive insurance claim.
Dealing with Stubborn Arms
Sometimes, even after a successful rv awning gas strut replacement, the awning might still act a bit wonky. If it's retracting unevenly, check the alignment of the arms. Over years of use, the fabric can shift slightly on the roller tube. If the fabric is pulled too far to one side, it puts extra stress on one strut while the other stays relatively relaxed. You can usually fix this by extending the awning and physically sliding the fabric back toward the center of the rail. A little bit of silicone spray in the tracks of the awning arms can also work wonders. Just avoid using heavy grease, as it tends to attract road dust and turn into a sticky paste that actually makes the problem worse.
When to Call in a Pro
Look, I'm all for DIY. Most people can handle this job in about thirty minutes. However, if your awning arms are bent or if the mounting brackets are pulling away from the side of your RV, a new strut isn't going to fix the underlying structural issue. If you're smelling electrical burning when you hit the switch, or if the motor is making a high-pitched grinding sound, the problem might be the motor struggling against a seized pivot point rather than a bad strut. In those cases, it's worth having a tech look at it so you don't burn out a $500 motor trying to save $60 on a strut.
Final Thoughts on Maintenance
Once you've finished your rv awning gas strut replacement, you can keep the new ones happy by simply using the awning. These seals stay supple when they're moved. If your rig sits in storage for six months, those seals can dry out and "stick" to the internal shaft. When you finally open it up, that first movement can tear the seal. Every once in a while, even if you're just parked in the driveway, run the awning in and out to keep things lubricated.
Taking care of this small maintenance task makes a world of difference in your camping experience. No more propping up the arms with a broomstick or worrying that a light breeze is going to collapse your shade. It's one of those "weekend warrior" fixes that provides immediate satisfaction the next time you're sitting outside enjoying the view. Just take your time, get the right part numbers, and don't forget that helper to hold the ladder!
