The steering stabilizer (dampener) just isn't pictured or it is behind the drag link. That is not my Jeep. That is from www.4x4xplor.com's website - a GREAT site for basic DIY maintenance and upgrades.
 
My steering setup is stock with the exception of aftermarket swaybar disconnects (like those shown in the pic), aftermarket track bar (made by JKS), and a tie rod for a Grand Cherokee (since it is thicker and stronger). Geometries are 100% the same though.
 
For checking the loose nuts, have somebody sit behind the wheel. Start the Jeep. Have them slowly steer back and forth at your command.
 
1. Check the joints for the trackbar (frame and lower passenger axle). If there is any movement, they need to be tightened down.
2. Check the tierod ends. If the do anything OTHER than rotate the bar a tiny bit (ie there appears to be play), tighten em down.
3. Check the drag link ends. If it is loose at the steering box, tighten as best you can.
4. If you can jack up your front a bit so wheels are off the ground, do that. Then grab the top and bottom of the tire and see if you can 'rock' the wheel back and forth. It may have a tiny bit of play, and that is normal. If it seems excessive, your ball joints may be toast.
5. While it is jacked up, grab one end of the axle and see if you can 'rock' it forward and back. If you can move it excessively, your control arm bushings may be worn and may need replacement.
 
Most likely, you'll find one of those to be the case.
 
As for tightening down, a torque wrench is a GREAT investment and you can find them at harbor freight fairly inexpensively. You can also pick up a Haynes manual from places like Autozone for about 20.00. I'm not mechanically inclined when I started, but now have no problems working on my Jeep at all.

Thank you for the tips. I do have a torque wrench that I bought from Harbor Freight about 5 years ago. I'll do the checks you listed. Hope you'll be around because I think I'll be needing a crash course in Jeep fixer-uppers.

I'll be around. I could give you my email if that would help. I posted it in the regular Jeep Wrangler forum in response to a new Jeep for a teen.

Yes, I would really appreciate it if you would give me your email address or direct me as to where I can get it. I have lots of questions about this. I owned only one Jeep before back in the early '70s and that was a CJ-6 with a 350ci, 4bbl carb. I really loved that thing but had to sell it since I was doing more and more highway driving at the time. My son (about 3 1/2 yrs old at the time) and I used to do a lot of off road antics and mudding. That Jeep had nice tight steering and was very stable. Of course it was larger than what they have now-a-days but I'm not complaining about that. LOL
 
Anyhow, I want to learn as much as I can about this newer one. I sent off for a repair manual but it only goes up to 2003. I didn't think they had changed much up to '06 so I ordered it.
 
Before I go on, I want to explain that I'm merely an old woman (58) who tries to do my own wrenching as much as possible. In my younger years it was more fun than anything else but these days with the prices repair shops charge and the awful rip-offs, I find I am in 'need' to do my own work when I can. I hope this fact (that I'm a woman) doesn't turn you off on helping me out.
 
Later on I want to learn how to make my own cold air induction system hoping to gain a little more horsepower and maybe save a tad on gas useage.
 
I do want to tell you that I appreciate your offer. Thank you!

Why would your age turn me off of helping? I ain't exactly young.
 
my email is skimblzbvs at yahoo dot com. That's the email I use for this stuff. If you got the haynes manual, I think that is the right one. I have the factory service manual for your year as well, but those kinds of repairs are probably more than you need to worry about. I can help ya as much as possible. When you contact me, I have a few things you can try.

I'm hoping the manual will be here by tomorrow. I'll let you know. Thank you for your email address. I'll send you an email so you have mine as well.

I've read way to much about the Deat Wobble the past couple of days. This is my first Jeep. It's a 2007 Wrangler Unlimited Sahara. I haven't done a single thing (alteration wise) to it since I bought it brand new from the dealer. I've had it since Jan. 07 and the "wobble" has started. Of course, I'm still under warranty and the dealer has ordered me a new damper to "repair" the problem. I'm only 8K miles away from the warranty expiring so I want to make sure everything is taken care of. What do you suggest I do if the damper will only mask the problem for a short while?

I had this problem after only 13,000 miles on my 2003. Jeep service said the steering damper was bad and I replaced it. Although this helped, the problem was still there. I went to buy new tires since they always seemed like they were out of balance but asked the tire dealer to check the track bar first. Quite a few people have commented on this site about it being the problem. The dealer found a small amount of movement in the track bar which shouldn't be there, replaced it, and the car drives like a new one. It doesn't shimmy, the car now feels solid, and so far the wobble has not returned. I suggest having this checked which is easy to do for a technician. The dealer did tell me that there is a new steering damper out for the 2003 which was over double the price of the original which makes me suspect it might have caused the track bar wear. Anyway, good luck in finding the problem.

Jim, Thanks for the input. I'm taking the Jeep in tomorrow to check out the track bar.

It isn't just the track bar you should check out. Any joints or steering components should be considered.
 
Consider:
1. Control arm bushings - if they are worn, you may get play in the axle.
2. Tie rod ends - ensure greased, intact, and no lateral movement (may have some rotation due to the joint type).
3. Track bar - check BOTH ends (frame and axle)
4. CV joints - jack tire up and check for motion top to bottom /\ kinda thing.
5. Draglink/tie rod. make sure that connection is secure as well.
 
If the problem has cropped up, you should also ensure your tires are properly balanced and have even wear.
 
IF you replace the steering stabilizer/dampener, I'd suggest at least getting a good aftermarket one, like Old Man Emu or something. That stock unit is so so. That will be my next acquisition.
 
As an FYI, I'm on 33" tires with NO death wobble at all. Aftermarket track bar (JKS), and a Grand Cherokee tie rod (stronger). I did swap out my control arms back in August to newer, unbent ones. I did notice my trackbar loose at one point, but the only issue I had from it was loose/sloppy steering.
 
If you look at this pic, you can see the primary components for the front suspension. Any of those points being loose can create havoc.
