Welcome to Grafco Electric, your trusted resource for all your automotive maintenance needs. In this comprehensive guide, we will provide you with detailed instructions on inspecting and replacing rubber exhaust hangers for your vehicle. Ensuring that your exhaust system is properly supported is crucial for optimal performance and longevity.

Why Are Rubber Exhaust Hangers Important?

Rubber exhaust hangers are responsible for securing various components of your vehicle's exhaust system in place. These hangers are crucial for minimizing vibrations, reducing noise, and preventing excessive strain on other exhaust components. Over time, rubber hangers may wear out or become damaged due to exposure to heat, environmental factors, and general wear and tear.

Inspecting Rubber Exhaust Hangers

Regularly inspecting your rubber exhaust hangers is essential to identify any signs of wear or damage. Here are some steps to follow for a thorough inspection:

Step 1: Vehicle Preparation

Before inspecting your rubber exhaust hangers, ensure that your vehicle is parked on a level surface and the engine is turned off. It's also a good idea to let the exhaust system cool down to avoid any potential burns.

Step 2: Visual Inspection

Carefully inspect each rubber exhaust hanger for any visible signs of wear, such as cracks, tears, or deformation. Ensure that the rubber is still flexible and not hardened or brittle. Look for any signs of disconnection or misalignment between the hanger and the exhaust system components it supports.

Step 3: Manual Inspection

Gently apply pressure on each hanger to check for any excessive movement or sagging. A properly functioning rubber hanger should provide adequate support without allowing the exhaust components to hang too low or make contact with the undercarriage of the vehicle.

Step 4: Functional Check

If you notice any deficiencies during the visual and manual inspection, it's important to test the functionality of the rubber exhaust hangers. Start the engine and listen for any unusual vibrations, rattling sounds, or excessive movements of the exhaust system. These can be indicative of worn or damaged hangers.

Replacing Rubber Exhaust Hangers

If your rubber exhaust hangers show signs of wear or damage, it is crucial to replace them promptly to maintain the integrity of your exhaust system. Follow these steps to replace the hangers:

Step 1: Gather the Necessary Tools

Before starting the replacement process, make sure you have the following tools ready:

  • Jack or ramps
  • Socket wrench set
  • New rubber exhaust hangers
  • Safety gloves and goggles

Step 2: Vehicle Elevation

Raise the front or rear of your vehicle using a reliable jack or ramps, ensuring proper safety precautions are taken. Consult your vehicle's owner manual for specific jacking points.

Step 3: Identify and Remove Existing Hangers

Locate the rubber exhaust hangers that require replacement based on your earlier inspection. Use a socket wrench appropriate for the hanger's bolts and remove them carefully. Be cautious when handling the exhaust system components.

Step 4: Install New Rubber Exhaust Hangers

Take the new rubber exhaust hangers and insert them into the corresponding hanger brackets. Make sure they are securely attached to both the exhaust system components and the vehicle's frame. Tighten the bolts using the socket wrench.

Step 5: Lower the Vehicle

Safely lower your vehicle using the jack or ramps, ensuring stability and proper alignment.

Step 6: Final Inspection and Functional Test

Perform a final inspection of the newly installed rubber exhaust hangers to ensure they are properly secured and aligned. Start the engine and listen for any abnormal sounds or vibrations, indicating a successful replacement.


By following these detailed instructions for inspecting and replacing rubber exhaust hangers, you can effectively maintain the performance and reliability of your vehicle's exhaust system. Remember, if you lack the necessary tools, expertise, or confidence to perform this task yourself, it is always recommended to seek professional assistance from trusted automotive service providers like Grafco Electric. Regular maintenance and timely replacements will significantly contribute to the longevity and optimal functioning of your vehicle's exhaust system.
