Key Features:
- Consistent Ride: Velocity Proportional Valving (VPV) technology and all-weather fluid with special additives reduce friction for a smoother ride.
- Reliable Performance: Nitrogen gas-charge maintains tire-to-road contact, improving ride and handling by reducing aeration.
- Restores Ride and Handling: A larger bore provides more efficient damping control for consistency and a smooth ride (where applicable).
- Durability: Self-lubricating fluid seal retains gas and reduces friction, preventing premature wear. Banded piston and bronze reinforced guide enhance durability.
- OE Specification: Designed and validated to meet original equipment (OE) specifications for consistent performance.
2. Compatibility and Pre-Installation
Before proceeding with installation, it is crucial to verify that this shock absorber is compatible with your specific vehicle. Incorrect parts can lead to improper function and potential safety hazards.
Vehicle Compatibility:
- 1978-1979 Ford Bronco
- 1977-1977 Ford F-150
- 1978-1979 Ford F-150
Important: Always research and confirm compatibility by entering your vehicle's year, make, model, engine, and trim information. Check any qualifier notes provided by the manufacturer or retailer.

3. Installation (Setup)
Installation of shock absorbers requires specialized tools and knowledge. It is highly recommended that installation be performed by a qualified automotive technician. Improper installation can compromise vehicle safety and performance.
General Installation Steps (Professional Installation Recommended):
- Prepare Vehicle: Safely lift and support the vehicle on a level surface. Remove the wheel(s) corresponding to the shock absorber being replaced.
- Remove Old Shock: Locate and carefully remove the fasteners securing the old shock absorber to the vehicle's chassis and suspension arm.
- Inspect Mounting Points: Clean and inspect the mounting points for any damage, corrosion, or wear. Replace any worn components as necessary.
- Install New Shock: Position the new Monroe Monro-Matic Plus 32285 shock absorber. Secure it using the provided hardware (bushings, washers, nuts) and appropriate torque specifications. Ensure all components are correctly oriented.
- Reassemble: Reinstall the wheel(s) and lower the vehicle safely.
- Final Check: After installation, perform a visual inspection to ensure all connections are secure and there is no interference with other components.

4. Operation
Once installed, the Monroe Monro-Matic Plus 32285 shock absorber operates continuously as part of your vehicle's suspension system. It is designed to control spring and suspension movement, ensuring tires remain in contact with the road surface for optimal control and comfort.
How it Works:
- The shock absorber dampens oscillations caused by road irregularities and vehicle movement.
- Velocity Proportional Valving (VPV) adjusts damping force based on the speed of suspension movement, providing a consistent and smooth ride across various conditions.
- The nitrogen gas charge helps to reduce aeration (foaming) of the hydraulic fluid, maintaining consistent damping performance even under demanding conditions.

5. Maintenance
Proper maintenance of your vehicle's suspension components, including shock absorbers, is essential for safety and longevity. While shock absorbers are generally sealed units, regular inspection is recommended.
Recommended Maintenance:
- Regular Inspections: During routine vehicle service, have your shock absorbers inspected for signs of wear, damage, or fluid leaks.
- Check for Leaks: A visible fluid leak on the shock absorber body indicates a seal failure and requires replacement.
- Inspect Bushings: Check the rubber bushings at the mounting points for cracks, deterioration, or excessive play. Worn bushings can lead to noise and reduced effectiveness.
- Listen for Noises: Unusual knocking, clunking, or squeaking sounds from the suspension area may indicate a problem with the shock absorbers or other suspension components.

Replace shock absorbers in pairs (front or rear) to maintain balanced handling and ride characteristics.
6. Troubleshooting
If you experience issues with your vehicle's ride or handling after installing or while using Monroe Monro-Matic Plus shock absorbers, consider the following common troubleshooting points:
Common Issues and Solutions:
- Excessive Bouncing or Swaying:
- Cause: Worn shock absorbers, incorrect part for vehicle, or improper installation.
- Solution: Inspect shocks for leaks or damage. Verify correct part application. Re-check installation for proper torque and component seating.
- Unusual Noises (Knocking, Clunking):
- Cause: Loose mounting hardware, worn bushings, or internal shock damage.
- Solution: Tighten all mounting bolts to specification. Inspect bushings for wear and replace if necessary. If noise persists, the shock may be faulty and require replacement.
- Harsh Ride or Stiffness:
- Cause: Incorrect shock absorber for vehicle application, or other suspension components (e.g., springs) are worn.
- Solution: Confirm the shock absorber is the correct model for your vehicle. Have a professional inspect other suspension components.
- Fluid Leaks:
- Cause: Damaged seal.
- Solution: A leaking shock absorber must be replaced.
If troubleshooting steps do not resolve the issue, consult a certified automotive technician for diagnosis and repair.
