Any time you remove the control arms, and especially the track bars, it is very likely you will have issues lining up the bolt holes. You could use a come-along or a Hi-lift jack, but our favorite method for realigning the axle in the frame is to use a ratcheting tie-down strap. Just like the control arms, if you are putting an adjustable track bar in, adjust it to be close to the stock track bar. We went about 3/8-inch longer than stock, but higher lifts will require more length to keep the axle square under the Jeep. If you can afford it, we suggest adjustable track bars whenever possible.
