Parts Included

The Monroe Monro-Matic Plus 801680 Suspension Strut typically includes the following components:

• Monroe Monro-Matic Plus 801680 Suspension Strut assembly
• Parts Pack(s) (e.g., mounting hardware, nuts)

Note: Additional components such as dust boots, jounce bumpers, or spring isolators may be sold separately and are recommended for a complete replacement.

Setup and Installation

This section outlines the general steps for installing the Monroe Monro-Matic Plus 801680 Suspension Strut. Specific procedures may vary by vehicle make and model. Always consult your vehicle's repair manual for detailed instructions.

Tools Required:

• Vehicle jack and jack stands
• Wheel lug wrench
• Socket set and wrenches (metric/standard as required)
• Torque wrench
• Penetrating oil (optional)
• Spring compressor (if disassembling strut assembly)

Installation Steps:

1. Prepare Vehicle: Park the vehicle on a level surface, engage the parking brake, and block the wheels. Loosen the lug nuts on the wheel corresponding to the strut being replaced.
2. Lift Vehicle: Safely lift the vehicle using a jack and support it securely with jack stands. Remove the wheel.
3. Access Strut: Locate the strut assembly. You may need to remove brake lines, ABS sensor wires, or sway bar links that are attached to the strut.
4. Remove Old Strut: Loosen and remove the lower mounting bolts connecting the strut to the steering knuckle or control arm. Open the hood and remove the upper mounting nuts securing the strut to the vehicle's chassis. Carefully remove the old strut assembly.
5. Prepare New Strut: If transferring the coil spring, top mount, or other components from the old strut, use a spring compressor to safely compress the spring before disassembly. Install the spring and other components onto the new Monroe 801680 strut.
6. Install New Strut: Position the new strut assembly into the vehicle. Secure the upper mounting nuts first, then align and secure the lower mounting bolts. Ensure all attachments are properly seated.
7. Reconnect Components: Reattach any brake lines, ABS sensor wires, or sway bar links that were disconnected.
8. Torque Fasteners: Torque all mounting bolts and nuts to the vehicle manufacturer's specifications. This is critical for safety and proper performance.
9. Reinstall Wheel: Reinstall the wheel and hand-tighten the lug nuts.
10. Lower Vehicle: Carefully lower the vehicle to the ground. Torque the lug nuts to the manufacturer's specifications.
11. Final Check: Bounce the vehicle a few times to settle the suspension. Check for any loose components or unusual noises.

Operating Considerations

Once installed, the Monroe Monro-Matic Plus 801680 Suspension Strut will immediately begin to provide improved ride comfort and handling. No specific operational adjustments are typically required after installation.

• Initial Ride: The vehicle's ride height may settle slightly after a few days of driving as the new components break in.
• Alignment: It is highly recommended to have a professional wheel alignment performed after replacing any suspension components, including struts. This ensures proper tire wear and vehicle handling.

Maintenance

Monroe Monro-Matic Plus struts are designed for long-lasting performance with minimal maintenance. However, regular inspection of your vehicle's suspension components is crucial for safety and longevity.

• Periodic Inspection: During routine vehicle maintenance (e.g., oil changes, tire rotations), visually inspect the struts for signs of wear, damage, or fluid leaks.
• Check Mounting Points: Ensure all mounting bolts and nuts remain tight. Re-torque if necessary according to vehicle manufacturer specifications.
• Dust Boots/Jounce Bumpers: If optional dust boots and jounce bumpers were installed, check their condition. Replace if torn or damaged to protect the strut rod.

Note: A properly functioning strut should not show signs of fluid leakage around the piston rod seal. Any visible fluid indicates a failing strut that requires replacement.
