How to Narrow a Crown Vic IFS
If you’re a fan of customizing your Crown Vic, you might have come across the need to narrow the IFS (Independent Front Suspension) arms. This modification can enhance the vehicle’s handling and give it a more aggressive look. In this article, we will guide you through the process of narrowing a Crown Vic IFS, ensuring a smooth and successful installation.
Understanding the IFS System
Before diving into the narrowing process, it’s essential to understand the Independent Front Suspension system. The IFS is a suspension setup that allows each wheel to move independently, providing better handling and ride quality compared to solid axles. The IFS system consists of several components, including control arms, ball joints, and strut rods.
Materials and Tools Needed
To narrow your Crown Vic IFS, you will need the following materials and tools:
– New control arms with the desired width
– Control arm bushings
– Ball joints
– Strut rods (if necessary)
– Wrenches, sockets, and torque wrench
– Jack and jack stands
– Wheel chocks
– Grease
Preparation
Before starting the narrowing process, ensure that your Crown Vic is on a flat and secure surface. Place wheel chocks on the opposite side of the vehicle to prevent it from rolling. Engage the parking brake and set the emergency brake.
Removing the Old Control Arms
Begin by removing the lug nuts and wheels. Next, locate the bolts that secure the control arms to the frame and the strut rods to the control arms. Use the appropriate wrenches and sockets to loosen and remove these bolts. Once the bolts are out, gently remove the old control arms from the vehicle.
Installing the New Control Arms
Now that the old control arms are removed, it’s time to install the new ones. Start by placing the new control arms in their mounting positions. Ensure that the ball joints are properly aligned with the control arm holes. Insert the bolts and tighten them to the manufacturer’s specifications using a torque wrench.
Adjusting the Strut Rods
If you’re narrowing the IFS, you may need to adjust the strut rods. Remove the strut rod from the control arm and install it on the new control arm. Tighten the bolts to the manufacturer’s specifications.
Reinstalling the Wheels and Final Adjustments
With the new control arms and strut rods in place, reinstall the wheels and tighten the lug nuts. Lower the vehicle and remove the jack stands. Finish by torquing the lug nuts to the recommended specifications.
Finishing Touches
Finally, apply grease to the ball joints and bushings to ensure smooth operation. Double-check all bolts and connections to ensure they are tight and secure. Take your Crown Vic for a test drive to verify that the narrowing process has improved the vehicle’s handling and ride quality.
By following these steps, you can successfully narrow your Crown Vic IFS and enjoy a more customized and performance-oriented driving experience.
