Replacing exhaust hangers is a common maintenance task for vehicle owners and mechanics. Proper lubrication during replacement ensures the hangers are easy to install and prevents damage to the exhaust system. Following best practices can save time and extend the lifespan of the hangers.
Preparation Before Lubrication
Before applying any lubricant, inspect the exhaust hangers and surrounding components. Remove any rust, dirt, or debris that could hinder the lubrication process. Using a wire brush can help clean stubborn areas.
Choosing the Right Lubricant
- Silicone spray: Ideal for rubber hangers as it does not degrade rubber material.
- Graphite lubricant: Suitable for metal-on-metal contact, reducing friction.
- WD-40 or similar penetrating oils: Useful for loosening rusted or stuck hangers before lubrication.
Applying the Lubricant
Apply the lubricant evenly to the inside of the rubber or metal parts of the hanger. For rubber hangers, a silicone spray is preferred to avoid deterioration. For metal components, a graphite lubricant can reduce friction during installation.
Ensure the lubricant reaches all contact points to facilitate smooth installation and removal. Avoid over-lubricating, as excess can attract dirt and debris.
Installation Tips
Once lubricated, carefully slide the exhaust hanger into position. Use gentle force to prevent damage. If the hanger is difficult to install, apply additional lubricant or use a rubber mallet to tap it into place gently.
Post-Installation Care
After installation, check the hangers for proper fit and clearance. Reapply lubricant if necessary to maintain flexibility and prevent squeaking. Regular inspections can help identify wear or damage early.
By following these best practices, you can ensure a smooth replacement process and extend the life of your exhaust hangers and system.
