Installation Instructions
Installation of suspension components requires specialized tools and knowledge. It is highly recommended that this procedure be performed by a qualified automotive technician. Improper installation can lead to vehicle damage, loss of control, and serious injury.
General Installation Steps (Consult Vehicle-Specific Service Manual for Detailed Procedures):
- Preparation: Safely lift and support the vehicle on jack stands. Remove the wheel.
- Disassembly: Disconnect any brake lines, ABS sensors, or sway bar links attached to the strut assembly. Carefully remove the lower strut mounting bolts and the upper strut mount nuts from the vehicle chassis.
- Strut Removal: Remove the entire strut assembly from the vehicle.
- Spring Compression: Using a certified spring compressor, safely compress the coil spring. This step is critical and dangerous if not performed correctly.
- Old Mount Removal: Once the spring is compressed, remove the top nut securing the old strut mount to the strut shaft. Remove the old strut mount, bearing, and any associated components.
- New Mount Installation: Install the new Monroe Strut-Mate 908997 strut mount, bearing, and isolators in the correct orientation onto the strut shaft. Ensure all components are seated properly.
- Secure New Mount: Tighten the new top nut to the manufacturer's specified torque.
- Spring Decompression: Carefully release the spring compressor.
- Reinstallation: Reinstall the strut assembly into the vehicle, securing the upper strut mount nuts and lower strut mounting bolts to the manufacturer's specified torque.
- Reconnect Components: Reconnect all brake lines, ABS sensors, and sway bar links.
- Final Checks: Lower the vehicle, perform a final torque check on all fasteners, and have a professional alignment performed.
