[quote name='UnderwaterMadman']I will not be using it as a daily driver. I am looking at mostly just weekend cruising around town with the top down and some trails with light mud/medium mud.
Not really on a budget per se, but since this is not going to be my main vehicle I would like to keep it around $8k at the max including any lift/tires I will need, but can wait and exceed the budget if necessary?
Do I need lockers? Front and rear, or will just rear do?
I am in NY and we salt the roads like crazy, how much rust on the under body is to much?[/QUOTE]
Alrighty, sorry for the delay.
Out of the choices of CJ, YJ, and TJ, in my opinion your best bet will be a TJ. 98-00 TJs can be had pretty cheap (well under $10k) and for the most part, the TJ fixed everything that was wrong in the YJ which fixed everything that was wrong in the CJ, etc.
A couple of things you should look for when getting your TJ include making sure it has the 4.0 I6 engine. The little 4 cylinder is just not worth it. Also try and make sure that the Wrangler you are getting has a rear Dana 44 axle (this should be standard on Sahara editions and those with the 30 inch tire and wheel group, but double check to be sure). The Dana 44 should provide you with fewer headaches than a Dana 35 (the other standard axle), and trust me on this, I know from experience. Also be sure to have a mechanic check out the axles and the transfer case.
As far as rust, I live in IL and we salt the roads quite a bit as well. If the rust on the underside is all surface rust, it should be fine and if you're adventurous you can spend a couple days on the underside sanding and repainting if you really feel like it. If the rust is so bad that the metal is actually starting to flex and tear, skip it.
I never wheeled with lockers and I went through some pretty interesting situations. I don't believe they are essential from the start, so I'd wait on them before you decide to put more money in.
For lift and tires, if you want it on the cheaper side, you can get a real basic coil spring lift and 31 inch tires and be pretty good to go for under $500. If you're looking for something more like fitting 33 inch tires, check out the Rubicon Express 3.5 Super Flex kit. It's about a grand, but Rubicon Express makes the top of the line lifts.
