Air suspension systems provide a smooth ride, but leaks in the airbag struts can quickly compromise performance. While replacement is often recommended, a DIY Airbag Repair Kit offers a temporary or even long-term solution for minor leaks. This guide outlines a step-by-step process to patch and reinforce your airbag struts using readily available materials.
Repairing Airbag Struts with an Inner Tube
This method utilizes a motorcycle inner tube and vulcanizing cement to create a durable patch for your leaking airbag struts.
Gathering Your Airbag Repair Kit Materials
You’ll need:
- Vulcanizing patch cement (available at most auto parts stores)
- A motorcycle inner tube at least 20 inches in diameter, slightly smaller than the strut bag’s circumference
- A razor blade
- A method to apply 5 psi of pressure to the strut
Preparing the Strut and Inner Tube
- Remove the strut from your vehicle.
- Rig the strut to apply a maximum of 5 psi, ensuring it’s fully extended. This provides rigidity for the repair process.
- Cut the inner tube into 2-inch wide sections using a razor blade.
Applying the Patches
-
Apply a 2-inch wide strip of vulcanizing cement to the top of the airbag strut bag, following the cement’s instructions.
-
Allow the cement to dry until tacky.
-
Slide a 2-inch inner tube section onto the strut from the bottom, positioning it over the cemented area.
-
Roll the inner tube section upward, creating an O-ring shape that seals against the cemented area. Practice this step without cement first.
Layering the Patches
-
For subsequent sections, apply cement to 1 ¾ inches of the bag and ¼ inch of the previously installed patch. This ensures overlapping coverage.
-
Install the next inner tube section, overlapping the previous one by ¼ inch. Roll it up to create the O-ring seal.
-
Repeat this process until the entire airbag bag is covered.
Curing and Reinstallation
-
Allow the cement to cure for 24 hours before reinstalling the strut.
-
Once cured, carefully reinstall the repaired strut.
This DIY airbag repair kit method provides a cost-effective solution for addressing small leaks in your air suspension system. While it might not be a permanent fix, it can extend the life of your struts and restore ride quality. Remember to monitor the repair for any signs of failure and consider professional repair or replacement for larger leaks or persistent issues.
