Before jacking up the front end of the vehicle, you should always set a block or brick against the back tire.  This will stop the vehicle from rolling.

Use a floor jack to raise the front of the jeep.  I commonly use a three ton jack for this, it has always worked great!

Once the vehicle has been lifted to a comfortable height.  Place jack stands under the axle and be sure that they are secure.

Undo the lug nuts and remove the rims and tires.

I like to get everything out of the way and clear of clutter.  This makes for a great working environment and easily accessible for light.

Unbolt the stock Track bar at its lowest point first.

Once the bolt is removed, use a pry bar to separate the stock track bar from the bracket.

Remove the bolts at the bottom of the frame rail first.

Then the two bolts on the outside of the frame rail.  Be sure to not lose the bolt-plate that comes in from the other side of the frame rail...it will fall inside the steering gear heat shield above the frame rail on the ZJ, making your life more difficult because you'll have to remove the heat shield to get it back again.

Now that you have the stock track bar out, compare it to Kevins Offroad track bar.  Notice the difference in quality and how the track bar will now pivot on the bracket where the tie rod style stock one restricts.

Bolt the new track bar back into place starting with the lower frame rail bolts.

Then follow through with the outer frame rail bolts. 

When assembling the trackbar itself, lubricate the bushings with poly-urethane lubricant, which is mineral based rather than oil based grease. Normal oil based grease will degrade the poly bushing over time.   Once completed wipe off the excess.

On the lower track bar bracket, drill out the factory hole with a  ½” bit.  This will accommodate for the heavier bolts that are supplied with the kit.

Be sure to use lock tite on all the threads, this will ensure they do not come loose.

After aligning the vehicle over the axle (possibly using a ratchet strap) adjust the track bar and bolt up both ends using the upgraded hardware.  Tighten both ends of the trackbar to 90 ft lbs, of course using lock tite.

Here is the finished product all bolted in!!  Looks great!!!
