How To Install An Adjustable Rear Sway Bar

With our car on a hoist, we used screw jacks to hold the chassis mounts in place.

With the sway bar arms and chassis mounts in place, gently move the shield and the fuel line on the passenger-side framerail before welding. Then weld the chassis brackets to the framerails and the brackets as illustrated in MM's instruction sheet.

The finished weld work with the chassis mount installed on each side should look like this.

Once the chassis mounts are welded, remove the installation plates, which aren't used when the bar is installed. They're replaced with the spherical rod ends and hardware installed here. Assemble and install these per MM's instructions using the appropriate hardware. Reinstall the rear springs, shocks, and wheels. Here, the ends are attached to the forward holes in the chassis mount which is the full soft setting. Increase stiffness if necessary after testdriving the car. With the car's weight on its wheels (either on the ground, on ramps, or on a ramp hoist), check the alignment of the rod-end assemblies. To avoid binding, they should be vertical when viewed from the rear of the car. If adjustment is needed, it can be done by moving the bar's sideways location by resetting the shaft collars. The bar's overall width can also be adjusted by sliding the sway bar arms on the bar's splines. If their required width is beyond the range of adjustment allowed by the splines, use more washers on the rod-end mounting bolts.

Recheck alignment of the rod ends. They should be vertical or nearly vertical. If adjustment is necessary, loosen and pivot the axle mounts slightly on the axle, being careful to keep the orientation of each axle mount the same with respect to the opposite side in order to not undo previous alignments. Complete the installation by securely tightening the U-bolts as shown.
