5. Installation Instructions
The WOLFSTORM Fender Inner Liners are designed for a straightforward bolt-on installation. No drilling or modifications to your vehicle are typically required as they utilize existing factory mounting points.
5.1. Tools Required (Not Included)
- Socket Wrench Set
- Open-end Wrench Set
- Torque Wrench (recommended for proper fastener tightening)
- Protective Eyewear and Gloves
5.2. Pre-Installation Steps
- Safety First: Ensure the vehicle is parked on a level surface, the parking brake is engaged, and the engine is off. For easier access, you may lift the vehicle using a jack and secure it with jack stands. Remove the wheels if necessary for better access to the wheel well area.
- Clean the Area: Thoroughly clean the inner fender well area, removing any dirt, mud, or debris. This ensures a clean surface for installation and prevents contaminants from being trapped.
- Inspect Components: Before beginning, inspect all fender liners and hardware for any shipping damage or manufacturing defects.
5.3. Installation Procedure
- Remove Existing Components (if applicable): If your vehicle has existing inner fender liners or splash guards that need to be replaced, carefully remove them by unbolting them from the vehicle frame.
- Position the Liner: Take one of the WOLFSTORM inner fender liners (start with either front or rear, and one side of the vehicle). Carefully position it within the wheel well, aligning the mounting holes on the liner with the factory mounting points on your vehicle.
- Secure with Hardware: Begin to loosely install the provided bolts, washers, and nuts into the aligned mounting holes. Do not fully tighten any fasteners until all bolts are in place and the liner is properly seated.
- Adjust and Tighten: Once all hardware is loosely installed, adjust the position of the fender liner to ensure optimal fitment and coverage. Then, progressively tighten all fasteners using appropriate tools. Refer to your vehicle's service manual for specific torque specifications if available, or tighten securely to prevent loosening from vibrations.
- Repeat for Remaining Liners: Follow the same steps for the remaining inner fender liners (other front, and both rear).
- Final Check: After all liners are installed, double-check all fasteners to ensure they are securely tightened. Verify that the liners do not interfere with any suspension components or tire movement.

6. Operation and Function
Once installed, the WOLFSTORM Fender Inner Liners function as a protective barrier within your vehicle's wheel wells. They are designed to:
- Prevent Debris Accumulation: Significantly reduce the amount of mud, dirt, rocks, and other road debris that can enter and accumulate within the engine bay and other sensitive areas behind the wheels.
- Protect Vehicle Components: Shield critical components such as wiring, hoses, and suspension parts from direct impact and corrosion caused by environmental exposure.
- Enhance Cleanliness: Make it easier to clean the wheel well area, as the liners provide a smoother, more accessible surface compared to exposed vehicle frame and components.
- Improve Aesthetics: Offer a cleaner, more finished look to the wheel wells, especially beneficial for vehicles with aftermarket fender flares or lifted suspensions.

7. Maintenance
To ensure the longevity and continued performance of your WOLFSTORM Fender Inner Liners, regular maintenance is recommended:
- Regular Cleaning: Periodically clean the inner fender liners, especially after off-road excursions or driving in muddy/salty conditions. Use a hose to rinse off accumulated dirt and debris. A mild automotive soap and soft brush can be used for stubborn grime.
- Inspect for Damage: Regularly inspect the liners for any signs of damage, such as dents, cracks, or chipped paint, particularly after impacts or heavy use.
- Check Fasteners: Over time, vibrations can cause fasteners to loosen. Periodically check all mounting bolts and nuts to ensure they remain securely tightened. Re-tighten as necessary.
- Touch-Up Paint (if needed): If the powder coating becomes chipped or scratched, consider applying a rust-inhibiting touch-up paint to prevent corrosion and maintain the appearance of the liners.
8. Troubleshooting
While WOLFSTORM Fender Inner Liners are designed for easy installation and durability, you may encounter minor issues. Here are some common concerns and their solutions:
| Problem | Possible Cause | Solution |
|---|---|---|
| Liner does not align with mounting holes. | Incorrect positioning; minor manufacturing tolerance; vehicle frame variations. | Slightly adjust the liner's position. Ensure all bolts are loosely started before tightening any. If a hole is slightly off, gently manipulate the liner to align. Do not force. |
| Liner appears bent or damaged upon arrival. | Shipping damage; manufacturing defect. | Contact WOLFSTORM customer service immediately with photos of the damage. Do not attempt to install damaged parts if they cannot be easily straightened without compromising integrity. |
| Vibration or rattling noise after installation. | Loose fasteners; improper seating of the liner; interference with other components. | Check and re-tighten all mounting hardware. Ensure the liner is not touching any suspension or steering components. Verify no tools or debris were left in the wheel well. |
| Difficulty cleaning accumulated mud/dirt. | Infrequent cleaning; hardened debris. | Rinse regularly. For hardened mud, use a pressure washer (with caution, maintaining distance) or a stiff brush and automotive cleaner. |
