How to Replace a Front Sway Bar on a Jeep Wrangler

The sway bar or stabilizer bar on the front of the Jeep Wrangler is in place to keep the body from rolling on the suspension and improve the handling of the Jeep. You can replace the sway bay if necessary; replacement sway bars are available from Jeep and some auto parts stores. The sway bar on the front of your Jeep Wrangler runs over the top of the frame, making access to the mounting hardware much simpler than on other vehicles.

Instructions

1

Use a lug wrench to loosen the lug nuts on the front wheels, then raise the front of the Jeep off the ground with a jack. Position a set of jack stands under the front axle of the Jeep to support it, then remove the front tires and set them aside.

2

Locate the nut on the top of the stabilizer bar end link near the front coil spring. Use a wrench to remove the nut from the top of the end link and set it aside. Repeat on the opposite side of the Jeep, then lift the sway bar off the end links.

3

Move to the front of the Jeep and use a socket and ratchet to remove the four retaining bolts that secure the plastic valance on the frame just behind the bumper. Remove the valance to expose the sway bar bushings and mounts on top of the frame.

4

Use a ratchet and socket to remove the four bolts that hold the sway bar mounts to the frame. Lift the U-shaped retainers off the sway bar and set them aside. Lift the sway bar off the frame and remove it from the truck. Slide the bushings off the old bar and save them.

5

Slide the bushings onto the new sway bar after applying a small amount of grease to the inside of the bushing. Position the bushing and bar on the frame and install the U-shaped brackets over the sway bar and bushings.

6

Use a socket and ratchet to tighten the four retaining bolts. Install the plastic valance, tightening the retaining bolts until they are snug. Be careful not to crack the plastic valance.

7

Slide the sway bar onto the top of the end links near the coil spring on both sides of the suspension and thread the retaining nuts onto the top of the link. Torque the bolts to 45 ft.-lbs. with a torque wrench.

8

Install the front wheels and thread the lug nuts onto the wheel studs. Raise the front of the Jeep off the jack stands, then remove the stands from under the Jeep. Lower the jack until the tires are on the ground. Tighten the lug nuts with a lug wrench.
