I used these as well re-gearing my Cherokee a few weekends ago.I just installed gears in my TJ.
Every thing I needed I got from Harbor Freight.
Large earring puller Large Bearing Separator
Magnetic base Multipositional Magnetic Base with Fine Adjustment
6" Calipers 6" Digital Caliper
Dial Indicators 1" Travel Machinist's Dial Indicator
In top of that basic hand tools and a die grinder to make a set of set up bearings and you have everything you need to get install a set of gears.
I also used their hydrolic press quite extensivly - couldn't not have done it without that.
I needed a digital micrometer for measuring shims accurately. I used this rather than calipers.
A nice to have tool was the harbor freight seal and race driver but not needed.
I needed an inch pound bar torque wrench along with adaptors to go up to 1/2" drive for it to fit the pinion socket and check that preload.
A dremel to make setup bearings especially in the front end.
The master install kit came with my gear marking compound, and new bearings - I used my old ones as the setup bearings.
