Refer to your vehicle's service manual for specific exhaust system diagrams and hanger locations.
Installation Steps
- Preparation: Ensure the exhaust system is cool to the touch. Locate the existing or intended mounting points for the hanger insulator.
- Removal (if replacing): If replacing an old insulator, use a specialized exhaust hanger removal tool or a pry bar to carefully detach the old insulator from the exhaust rod and vehicle mounting point. Lubrication may assist in removal.
- Installation: Slide the new Walker 35017 insulator onto the exhaust system's hanger rod. Then, align the insulator with the vehicle's mounting stud or bracket and push it into place. Lubricating the holes of the insulator with a silicone-based lubricant can make installation easier.
- Securement: Ensure the insulator is fully seated on both the exhaust rod and the vehicle's mounting point, providing a snug and secure fit.

Operating Principle
The Walker 35017 Exhaust System Hanger Insulator functions as a critical component in supporting the vehicle's exhaust system. Its primary role is to absorb vibrations and movements generated by the engine and road conditions, preventing these from being transferred directly to the vehicle's chassis. This helps to reduce noise, prevent damage to exhaust pipes and catalytic converters, and maintain proper alignment of the exhaust system. The durable rubber construction ensures flexibility while providing firm support, allowing for slight movement of the exhaust system without causing undue stress or detachment.

Maintenance
Exhaust hanger insulators are generally low-maintenance components. However, periodic inspection is recommended to ensure their continued effectiveness and prevent potential issues with the exhaust system.
Inspection Schedule
- Inspect the insulators during routine oil changes or vehicle maintenance checks.
- Check immediately if you notice increased exhaust noise, rattling, or a change in the exhaust pipe's position.
What to Look For
- Cracks or Tears: Look for any visible cracks, tears, or signs of deterioration in the rubber material.
- Stretching or Sagging: Ensure the insulator is not excessively stretched or sagging, which could indicate wear or improper support.
- Secure Fit: Confirm that the insulator is still securely attached to both the exhaust rod and the vehicle's mounting point.
- Corrosion: Check surrounding metal components for rust or corrosion that could affect the hanger's integrity.
If any signs of wear or damage are observed, replace the insulator promptly to maintain proper exhaust system support and prevent further damage.

Troubleshooting
While exhaust hanger insulators are simple components, issues can arise if they fail or are improperly installed. Here are common problems and their potential solutions:
Common Issues and Solutions
- Rattling or Clunking Noise:
Cause: Loose, worn, or broken insulator; exhaust pipe hitting the chassis.
Solution: Inspect all exhaust hangers and insulators. Replace any that are damaged or no longer providing a secure fit. Ensure proper clearance between the exhaust pipe and vehicle components. - Exhaust Pipe Sagging or Misalignment:
Cause: Failed insulator; incorrect insulator size or type.
Solution: Replace the faulty insulator. Verify that the correct part number (Walker 35017) is used for your specific vehicle model. - Increased Vibration in Cabin:
Cause: Insulator no longer effectively dampening vibrations.
Solution: Check insulators for hardening, cracking, or excessive wear. Replace if the rubber has lost its elasticity. - Difficulty Installing Insulator:
Cause: Tight fit; lack of lubrication.
Solution: Apply a silicone-based lubricant to the holes of the insulator and the metal rods/studs. Use an exhaust hanger installation tool if available.
