Exhaust Hangers

Replace worn or damaged exhaust rubber hangers that support the exhaust system from the vehicle frame, restoring proper exhaust positioning and eliminating rattles or sagging.

Warnings

Tools required

Parts

• Exhaust hanger rubber insulator × 1 — Use OEM Ford specification or equivalent aftermarket

Preparation

1. Park vehicle on level surface and apply parking brake
2. Place wheel chocks behind rear wheels
3. Allow exhaust system to cool completely (minimum 1 hour after engine shutdown)
4. Raise vehicle using floor jack and support securely on jack stands at frame rails
5. Verify vehicle is stable before working underneath
6. Inspect exhaust system to identify which hangers need replacement (typically 3-5 hangers along system)

Procedure

1. 1

   Locate damaged exhaust hanger
   Identify the specific hanger requiring replacement. The F-150 exhaust system typically has hangers at the intermediate pipe, mid-pipe, and rear muffler sections. Inspect the rubber insulator for tears, separation, or excessive deterioration. Note how the hanger is oriented before removal for proper reinstallation.
2. 2

   Apply penetrating oil to hanger connection points
   Spray penetrating oil around the hanger where it connects to both the exhaust pipe bracket and the frame mount. Allow 5-10 minutes for penetration. This helps ease removal of the rubber insulator from the metal hooks.
3. 3

   Support exhaust system
   Position a floor jack with a block of wood under the exhaust pipe near the hanger being replaced to support the weight and prevent excessive movement. Raise jack just enough to take tension off the hanger but do not lift the exhaust significantly.
4. 4

   Remove old hanger from frame mount
   Using a pry bar or large screwdriver, carefully pry the rubber hanger off the frame-mounted hook. Work the rubber insulator side-to-side while applying leverage to walk it off the hook. The rubber may be stiff and require firm pressure. If the hanger is severely deteriorated, it may need to be cut off with a utility knife.
5. 5

   Remove hanger from exhaust bracket
   Once freed from the frame mount, remove the hanger from the exhaust pipe bracket using the same prying technique. The exhaust pipe will now be unsupported at this location, so ensure the floor jack is supporting the weight adequately.
6. 6

   Clean mounting points
   Use a wire brush to clean both the frame mount hook and the exhaust bracket hook, removing rust, rubber residue, and debris. Clean metal-to-rubber contact ensures proper seating and longevity of the new hanger.
7. 7

   Install new hanger onto exhaust bracket
   Position the new rubber hanger onto the exhaust pipe bracket first. Apply lubricant (soapy water or silicone spray) to the hook to ease installation. Work one hole of the hanger over the bracket hook, ensuring it is fully seated. The orientation should match the original hanger position noted during removal.
8. 8

   Install hanger onto frame mount
   With the hanger attached to the exhaust bracket, use a pry bar to stretch the rubber and position the second hole over the frame-mounted hook. This may require adjusting the jack height to align properly. Pull the hanger fully onto the hook until it is seated completely. Verify the hanger is not twisted and is properly oriented.
9. 9

   Remove jack support and verify alignment
   Carefully lower and remove the floor jack from under the exhaust. Check that the exhaust system hangs properly with adequate clearance from the frame, driveshaft, and fuel tank. The exhaust should be centered in any heat shield openings and should not contact any body components.
10. 10

    Inspect remaining hangers and connections
    While underneath the vehicle, inspect all other exhaust hangers for wear or damage. Check exhaust flange connections for leaks or looseness. Verify heat shields are secure and not contacting the exhaust pipe excessively.

Reassembly

1. No disassembly was required for this procedure
2. If multiple hangers were replaced, verify all are properly seated and the exhaust system has proper clearance throughout

Verification

• Start engine and listen for exhaust leaks or unusual noises
• Check underneath vehicle while running to verify exhaust is not contacting frame or body components
• Rev engine briefly and observe exhaust movement - it should move slightly but return to center position without excessive sagging
• Visually inspect that exhaust pipes maintain proper clearance from fuel lines, brake lines, and driveshaft throughout their length
• Test drive vehicle and listen for rattles or contact noises, especially over bumps
