3. Setup and Installation
Installation of the Eibach Pro-Kit requires specialized tools and mechanical expertise. It is highly recommended that installation be performed by a certified professional. Improper installation can lead to vehicle damage, poor performance, or safety hazards.
General Installation Steps (Professional Installation Recommended):
- Safety First: Ensure the vehicle is securely lifted on a hoist or jack stands on a level surface. Disconnect the battery.
- Remove Wheels: Carefully remove all four wheels.
- Disassemble Suspension: Following the vehicle manufacturer's service manual, carefully disassemble the existing suspension components (struts/shocks, springs, sway bar links, etc.). Note the orientation of all parts.
- Spring Replacement: Using a spring compressor (if applicable and safe for the specific strut design), carefully remove the original springs and install the new Eibach Pro-Kit springs. Ensure proper seating and orientation.
- Reassemble Suspension: Reassemble all suspension components, ensuring all bolts are torqued to the vehicle manufacturer's specifications.
- Reinstall Wheels: Reinstall the wheels and torque lug nuts to specifications.
- Lower Vehicle: Carefully lower the vehicle to the ground.
- Alignment: A professional wheel alignment is mandatory after installing lowering springs to ensure proper handling, tire wear, and safety.
Important: Always refer to the specific vehicle service manual for detailed torque specifications and component removal/installation procedures.
4. Operating Considerations
After installing the Eibach Pro-Kit, your vehicle's ride height will be lower. This may affect certain driving conditions:
- Clearance: Be mindful of reduced ground clearance when driving over speed bumps, steep driveways, or uneven terrain.
- Handling: The vehicle's handling characteristics will be sportier. Allow time to adapt to the new feel.
- Tire Wear: Proper alignment is crucial to prevent premature tire wear. Regularly inspect tires for uneven wear patterns.
5. Maintenance
The Eibach Pro-Kit springs are designed for durability and require minimal maintenance. However, regular inspection of your suspension components is recommended:
- Periodic Inspection: Annually inspect springs, shocks/struts, and other suspension components for signs of wear, damage, or corrosion.
- Cleanliness: Keep suspension components free from excessive dirt and debris.
- Alignment Checks: Consider periodic wheel alignment checks, especially if you notice uneven tire wear or changes in handling.
6. Troubleshooting
If you experience any issues after installation, consider the following:
| Symptom | Possible Cause | Solution |
|---|---|---|
| Uneven Ride Height | Improper spring seating; incorrect spring installation (front/rear mixed); suspension component issue. | Verify springs are correctly seated and installed. Inspect other suspension components for damage. Re-check installation. |
| Excessive Noise (clunking, squeaking) | Loose bolts; worn bushings; improper component assembly; foreign object. | Check all fasteners for proper torque. Inspect bushings for wear. Ensure no components are rubbing. |
| Poor Handling / Steering Pull | Incorrect wheel alignment; worn steering/suspension components. | Perform a professional wheel alignment. Inspect steering and suspension components for wear. |
If issues persist, contact a qualified automotive technician or Eibach customer support.
