getting ahead of possible death wobble in the future

so i'm a relatively new jeep owner and have an 96zj 4.0L with 211k and counting. this is my DD and any off-roading i do is likely a dirt road since i prefer to do trails on my mountain bike. i don't plan on any sort of lift and everything on the jeep is stock and from what the previous owner said all steering and suspension is original as well. my problem is a slight oscillation in the front driver side. every now and again it gets bad with the steering wheel shaking along with the front end to the point were i need to slow down until it stops all at speeds from 40-50. i don't have the tools to do most everything i would need to do but have family friends who can help. as paychecks allow i want to replace my steering and suspension and my question is what are some parts that will be reliable but won't break the bank and yes i already know i get what i pay for so i don't plan on going as cheap as possible but i'm not bill gates so any suggestions?

The oscillation you describe is death wobble. Common points of failure are the trackbar bracket holes wallowing out and control arm bushings. Balljoints, tie rod ends, and unbalanced wheels/tires can also be a problem. Anybody tells you a steering stabilizer will fix it they're wrong.

Check the track-bar first, loose bolt there is the easiest to fix.

Since you have the 4.0 it's a good idea to upgrade to the V8 steering linkage: http://www.amazon.com/Crown-Automoti.../dp/B008VPUOSO
If your CA bushings are worn (they are) I suggest getting whole new arms as beating the bushings out isn't worth the pain for the cost difference. Get moog, some of the off brands sell you the wrong parts.

Moog is very reasonable and quality. Go to their website and get the part numbers from there and then go to Amazon and start buying stuff. Amazon gets really sketchy when it comes to using their system for finding the correct parts. A Haynes manual will tell you how to do it and then you just need an alignment after you replace your parts. Like kg6mov said, trackbar, I'd start with the lower front control arms, and then get the moog front V8 steering tie rod, tie rod ends, and draglink. There are lots of write ups on replacing these parts in the forum

i read through a good bit of death wobble threads and the only thing stopping me from saying full on death wobble is that it isn't constant even going on dirt roads it will sometimes be perfectly fine and then days later after plenty of driving ill be on a recently repaved road i have a death grip on the steering wheel. thanks for the advice on parts and it never crossed my mind to get the v8 linkage so ill definitely look into as i put together my list of parts.

Death wobble in early stages takes a trigger to get the axle moving, a bump in the road or a magic speed.

Then it gets to the point where you can't go over 20mph without it trying to jump off the road.

You should be able to drive with the swaybar disconnected with no DW.
