Why isn't my axle centered (TJ)? -
On coil sprung Jeeps a track bar is used to locate the axle under the Jeep. When you lift a Jeep the track bar mounts are now farther apart, but the track bar is still the same length so the axle will be pulled off centered. To re-center the axle underneath the Jeep the track bar mounts must be relocated, or an adjustable track bar must be used. This image will help explain.
