What is this, a dd or off-roader, or both. Does it have a lift, what are you wanting to do with it as far as off-road ready. If it's a dd, go to a pull-it-apart junkyard. They sell axles complete for under $100. Just make sure you get an HP Dana 30 and that it's not a vacume disconnect type. If it's a wheeler, and tool storage and time, and space are a problem. Take the axles out, you'll need a hub socket and some of the tools above, and take them to a machine shop with a press. It costs $50 to replace the u-joints. Get some spicers and throw them back in there. If your shafts are messed up, again the pull-apart yard will have those too for around $30.
Track bar go buy a RE HD and put it on yourself, you'll need a tre pickle fork, and a BFH. Sway bar, buy some disconnects from Tere, RE, or JKS. This is easy stuff to do yourself. AGAIN, if this is you daily driver ocassional no lift off-roader. Go to pull it apart and get the parts. TRE's are cheap and easy to replace.
