The new bar bolts into the bracket with the high misalignment shims for maximum flexibility. All of the rod ends are Teflon lined, and all of the hardware is Grade 8 or better.

Our test truck has a 6-inch lift on it and sports LT315-70R17 tires. The owner was ready to sell it rather than deal with the insidious death wobble. In the top photo notice how the stock track bar is attached with a ball joint.....

......(A) at the axle and a bushing (B) at the frame. With this lift the ball joint is maxed out, and the angle of the track bar (C) doesn't match the angle of the draglink (D). The bottom photo shows the finished install with the drag link and track bar parallel as they should be.

While no welding is required for installation, minimal cutting is needed to get rid of the stock parts. The threaded portion of the ball joint end of the track bar needs to be cut off so the joint can be removed with the proper tool. An air grinder is the easiest way to do this.

With the threads cut off the ball joint, a remover is used to push the joint out of the cast section on the axletube. This mount is what the new WC Motorsports bar bracket will bolt to. Simply make sure the hole is round and clean for the installation.

The new bracket is installed on top of the mount for 6-inch and higher lifts, or underneath for up to 4-inch lifts. The 4140 machined steel piece comes with all the hardware needed to bolt it properly into place.

The rod end of the bar fits into the new bracket, and the bracket is tightened down. The bar is adjustable to center the axle under the vehicle and to adjust for manufacturing tolerances.

After the stock bar is removed from the frame bracket, the hole is reamed out with a 7/8-inch bit. Some brackets may become squished together if other aftermarket brackets have been used, so the brackets may have to be straightened to stock dimensions for the new rod end.

The new bar bolts into the bracket with the high misalignment shims for maximum flexibility. All of the rod ends are Teflon lined, and all of the hardware is Grade 8 or better.

The final steps are to replace the left upper ball joint shim with a fully adjustable style, and then have the alignment set at your favorite alignment shop. Off Road Unlimited had the whole job done in less than a day. The death wobble was cured for good!
