Maintenance
Hellwig LP-25 Helper Springs are designed for durability and require minimal maintenance. Periodically inspect the springs and mounting hardware for any signs of wear, damage, or looseness. Ensure all bolts and nuts remain securely tightened, especially after initial installation and heavy use.
Clean the springs as needed to remove dirt and debris, which can accumulate over time. No lubrication is typically required for the spring leaves themselves, as they are designed to operate dry.
Troubleshooting
If you encounter issues with your Hellwig LP-25 Helper Springs, consider the following common troubleshooting points:
- Sagging or Ineffective Load Leveling:
- Verify that the helper springs are correctly installed and adjusted according to the installation kit instructions.
- Ensure all mounting hardware, especially the U-bolts, are properly tightened. Loose hardware can reduce effectiveness.
- Confirm that the correct LP installation kit was used for your specific vehicle model. The helper springs themselves do not include mounting hardware, which is crucial for proper function.
- Check if the load exceeds the 2,500 lb. level load carrying capacity.
- Unusual Noises (e.g., Squeaking, Clunking):
- Inspect all contact points between the helper springs and the factory leaf springs for proper alignment and potential rubbing.
- Re-check the tightness of all mounting bolts.
- Difficulty with Installation:
- Ensure you have the correct LP installation kit for your vehicle. The helper springs are a universal component, but the mounting hardware is vehicle-specific.
- Refer to the detailed instructions provided with your specific installation kit.
If problems persist, it is recommended to consult a professional mechanic or contact Hellwig customer support.
