To start off, begin preparing for the installation by spraying all of the nuts & bolts now (!) with a penetrant like Kroil, Break-Free, Liquid Wrench, or PB-Blaster. No, WD-40 is not in that list, don't waste your time thinking it will work too... it won't.

Spray the hardware several times over a few days to give it time to work its way into the threads so the nuts & bolts will have the best chance of coming apart with no drama.

Don't forget that the very first thing you must do after installing the suspension lift is that you must (!) then adjust the toe-in of your front axle. A suspension lift pulls the front of your tires closer together which means it produces excessive toe-in which will quickly ruin your front tires.

This articcle shows how to do that, as well as how to re-center your steering wheel which will also be required. NO, you do not need to pay an alignment shop to do either, you can easily do both in your garage or driveway as acccurately as an alignment shop can do. Really.

Here's how... Basic Jeep Front End Alignment

Set your toe-in per the above instructions so the fronts of the tires are 1/16" to 1/8" closer together than they are in the rear. All you need to do this is a tape measure, wrench, and big water pump pliers or a pipe wrench to rotate the tie rod.

The below image shows a more repeatable method of measuring between the tires so you get the toe-in set properly. Basically two 1" square pieces of aluminum spring-clamped to your rotors, marked at points equal to your tire diameter. Measure between them at the front & rear & rotate the tie rod so the fronts are 1/16" to 1/8" closer than in the rear. :)
