2. Installation
Installation of the MOOG K80109 Caster/Camber Adjusting Bushing requires specialized tools and knowledge of automotive suspension systems. It is highly recommended that installation be performed by a qualified professional technician.
2.1 Safety Precautions
- Always wear appropriate personal protective equipment (PPE), including safety glasses and gloves.
- Ensure the vehicle is securely supported on jack stands or a lift before beginning work.
- Refer to the vehicle manufacturer's service manual for specific torque specifications and procedures.
- Disconnect the vehicle's battery if working near electrical components.
2.2 General Installation Steps (Professional Installation Recommended)
- Prepare Vehicle: Lift and secure the vehicle. Remove the wheel and tire assembly.
- Access Bushing: Locate the existing caster/camber bushing in the suspension assembly. This typically involves the upper control arm or spindle area, depending on the vehicle's suspension design (e.g., Ford Twin I-Beam).
- Remove Old Bushing: Carefully remove the pinch bolt. Use appropriate tools (e.g., chisel, pry bar) to extract the old bushing. Exercise caution to avoid damaging surrounding components.
- Install New Bushing: Insert the MOOG K80109 bushing into the designated location. Ensure correct orientation as per vehicle-specific instructions or alignment requirements.
- Secure Bushing: Reinstall the pinch bolt and tighten to the vehicle manufacturer's specified torque.
- Reassemble: Reinstall the wheel and tire assembly. Lower the vehicle.
- Professional Alignment: After installation, a professional wheel alignment is mandatory to correctly set caster and camber angles. This product provides the adjustability needed for alignment but does not perform the alignment itself.

3. Function and Adjustment
The MOOG K80109 bushing is an adjustable component designed to correct caster and camber angles in your vehicle's front suspension. These angles are critical for proper steering, handling, and tire wear.
3.1 Caster Adjustment
Caster refers to the forward or backward tilt of the steering axis when viewed from the side of the vehicle. Proper caster helps with steering stability and return-to-center feel. The K80109 allows for adjustment to bring this angle within manufacturer specifications.
3.2 Camber Adjustment
Camber is the inward or outward tilt of the wheel when viewed from the front of the vehicle. Correct camber ensures even tire contact with the road, preventing premature tire wear. The K80109 facilitates adjustment to achieve the correct camber angle.
3.3 Adjustment Process
Adjustment of the caster and camber angles using this bushing is performed during a professional wheel alignment. The eccentric design of the bushing allows technicians to rotate it, thereby shifting the position of the spindle and altering the alignment angles. This process requires specialized alignment equipment and should only be performed by trained personnel.
4. Maintenance
Once installed and properly aligned, the MOOG K80109 bushing requires minimal direct maintenance. However, regular inspection of your vehicle's suspension components is recommended as part of routine vehicle maintenance.
- Regular Inspections: Periodically check the bushing and surrounding suspension components for signs of wear, damage, or looseness.
- Alignment Checks: Have your vehicle's alignment checked periodically, especially after hitting potholes or performing other suspension work, to ensure the caster and camber remain within specifications.
- Cleanliness: Keep the suspension area free from excessive dirt and debris, which can contribute to premature wear of rubber components.
5. Troubleshooting
If you experience issues after installing the MOOG K80109 bushing, consider the following common problems and solutions. Many issues related to alignment components require professional diagnosis and repair.

Symptom: Loose Steering / Vehicle Wanders
This can indicate incorrect caster settings or worn steering components. A professional alignment check is necessary.

Symptom: Steering Wheel Vibration
While often related to tire balance, suspension component wear or incorrect alignment can contribute. Inspect all suspension parts.

Symptom: Vehicle Pulls to One Side
A common sign of incorrect camber or caster. Immediate professional alignment is required.

Symptom: Uneven Tire Wear
Often a direct result of improper camber or toe settings. Check tire pressure and seek professional alignment.
5.1 Bushing Movement
Some users have reported that adjustable bushings can "walk up and out of the knuckle" if not properly secured or if the bolt is not sufficiently tight. Ensure the pinch bolt is tightened to the manufacturer's specifications to prevent movement.
If you suspect any issue with the bushing or alignment, consult a certified automotive technician.
