RV Life: DIY Repair for Deteriorating Rubber

RVs are a fantastic way to travel and explore the open road. However, like any vehicle, they require regular maintenance and repairs to keep them in top shape. One common issue that many RV owners face is deteriorating rubber components. In this comprehensive article, we will guide you through DIY repairs for three common rubber-related problems in your RV: the exhaust hanger bracket, hydraulic jack seals, and muffler straps. With some basic tools and a little bit of know-how, you can tackle these repairs yourself and ensure that your RV stays in great condition.


Regular inspections of your RV are essential to catch any potential issues before they become major problems. This is especially true when it comes to deteriorating rubber components. Rubber parts, such as the exhaust hanger bracket, hydraulic jack seals, and muffler straps, can degrade over time and lead to more significant damage if not addressed promptly. By understanding the common issues with deteriorating rubber and conducting regular inspections, you can catch these problems early and save yourself time and money in the long run.

Inspecting the Exhaust Hanger Bracket

The exhaust hanger bracket is an essential component of your RV’s exhaust system. It supports the weight of the muffler and ensures that it stays securely in place. Over time, the rubber on the exhaust hanger bracket can deteriorate, leading to a loose or unstable muffler. To inspect the exhaust hanger bracket, you will need a few basic tools. Start by visually examining the rubber for any signs of deterioration, such as cracking, splitting, or sagging. Additionally, check for any excessive movement or unusual noises coming from the exhaust system.

Replacing the Exhaust Hanger Bracket

If you notice any issues with the exhaust hanger bracket during your inspection, it is essential to replace it promptly to prevent further damage. When replacing the exhaust hanger bracket, it is crucial to use the exact replacement part for your specific RV model. While there may be alternative options available at a lower cost, it’s best to stick with the manufacturer’s recommended part to ensure a proper fit and function.

Before replacing the exhaust hanger bracket, consider the type of glue you will use. The glue should be suitable for both metal and rubber and not melt or damage the rubber during the bonding process. Apply the glue to the metal hanger bracket and press it firmly against the rubber, holding it in place until it sets. Follow a step-by-step guide for replacing the hanger bracket to ensure a successful repair.

Dealing with Hydraulic Jack Seals

Hydraulic jacks are responsible for lifting and leveling your RV. These jacks rely on seals to prevent hydraulic fluid from leaking, maintain pressure, and ensure smooth operation. Over time, these seals can deteriorate, leading to leaks and potential damage to the hydraulic system. Regular inspections are crucial for identifying signs of deteriorating hydraulic jack seals.

During the inspection, carefully examine the seals for any signs of wear, such as cracks, tears, or leaks. If you notice any issues, it is essential to clean the hydraulic jack and seal thoroughly before proceeding with repairs.

Cleaning and Repairing the Hydraulic Jack Seal

Cleaning the hydraulic jack seal is a vital step in the repair process. Start by preparing the necessary cleaning materials, such as a Mr. Clean Magic Eraser and a blue scrubby pad. These tools will help remove any dirt, dust, or debris that may have accumulated on the seal and the bottom of the jack.

Once cleaned, scuff the seal to improve adhesion when applying the glue. Choosing the right glue is crucial to ensure a secure and long-lasting bond between the rubber seal and the metal components of the hydraulic jack. Avoid using glues that are not intended for use with rubber, as they may melt or damage the seal.

Apply the glue to the scuffed surface of the seal and press it firmly against the hydraulic jack, ensuring proper alignment. Hold the seal in place until the glue sets, following the manufacturer’s instructions. This repair should restore the integrity of the hydraulic jack and prevent further leaking or damage.

Replacing the Broken Muffler Strap

Muffler straps play a crucial role in supporting and securing the muffler to your RV’s exhaust system. Over time, these straps can become rusty, weakened, or completely broken. A broken muffler strap can lead to excessive movement and potentially cause damage to other components of the exhaust system.

If you notice a broken or deteriorating muffler strap during your inspection, it is essential to replace it promptly. Start by removing the old strap using a socket wrench. It can be helpful to spray the bolts with WD-40 a few days in advance to ease removal. Once the old strap is removed, select the appropriate replacement strap for your RV. While stainless steel straps may be preferable, galvanized straps can also provide durability.

Install the new muffler strap by aligning it with the muffler and exhaust system, ensuring a secure fit. It may be necessary to clean and reuse the original bolts, so take time to clean them properly using WD-40.

Quick and Easy Muffler Strap Replacement

Replacing the muffler strap may seem like a challenging task, but with the right techniques and tools, it can be a quick and easy repair. Start by using WD-40 to lubricate the bolts and ensure they are easy to remove. This step will help prevent any unnecessary frustration or difficulty when reaching and loosening the strap bolts.

With the bolts loosened, reach up to the muffler bracket and remove the broken strap. Take this opportunity to select the appropriate galvanized strap for replacement. Galvanized straps are corrosion-resistant and can withstand the harsh environment of your RV’s exhaust system.

Follow a step-by-step guide for replacing the muffler strap, ensuring a secure and proper installation. Once the new strap is in place, consider cleaning and reusing the original bolts. Cleaning them with WD-40 will remove any dirt or debris and help prevent future issues with rust or corrosion.

Inspecting Other Areas of the RV

While addressing the exhaust hanger bracket, hydraulic jack seals, and muffler straps is essential, it is equally crucial to inspect other areas of your RV for signs of deteriorating rubber. Pay close attention to components such as window seals, door seals, slide-out seals, and roof vents. Look for any visible signs of cracking, crumbling, or sagging.

Regular inspections and proactive maintenance can prevent small issues from turning into costly repairs later on. By taking the time to inspect and address potential issues with deteriorating rubber components, you can extend the lifespan of your RV and preserve its value.


Maintaining your RV is an essential part of being a responsible owner. Regular inspections and DIY repairs can save you time, money, and stress in the long run.
