First, a little bit of back story.

I've got a 96 cherokee country that I installed a 3" BB and hydro 7000 shocks on almost a year ago. Prior to the lift install I had 1 instance of death wobble happen on the highway at about 65mph. Shortly after the lift was installed I put a new track bar bushing in and did not have any DW issues until just recently.

Now the current issue.

I've had 2 DW outbreaks in the past 2 weeks. This provoked me to start looking around underneath. Only now do I notice that my axle is not centered from the lift. This I understand. But I'm not sure why my track bar and drag link are not perfectly parallel. If I understand it correctly, (which I may not) shouldn't those two remain parallel as long as nothing is changed about the mounting points? (I.e pitman arm drop, tb drop bracket)

I'm pretty sure I can chalk my dw up to a combination of poor alignment (apparent by horribly unevenly worn tires) and said unevenly worn tires and also I think my driver side caliper is sticking slightly.

Anyway, I attached a pic of my suspension geometry, maybe it's not as bad as it seems to me. someone set me straight if I'm wrong about anything here. Sorry for the crappy pic and thanks for your replies!

I added the arrows just because everything is so muddy and dirty it was hard to tell things apart haha

At 3" of lift , your steering geometry is fine. After the lift, what did you do with/for the track bar to re-center the axle under the body ? Re-drill the axle side hole, lift kit bracket, aftermarket track bar, or nothing ?

Nothing lol. I only just noticed it a week or two ago. I'm debating re drilling or just buying an adjustable tb right now.

CJ7-Tim 08-26-2013 05:00 PM

Get the axle correctly centered under the body. At about 2-3" of lift you should be considering an aftermarket adjustable track bar instead of a Band-Aid fix that may cause issues later on.

Well here's an idea that I just recently started to formulate...

When I installed the new tb bushing, the hole was very wallowed out. So I drilled the hole out larger an used a larger bolt. Now I'm thinking of maybe cutting the whole axle side mount off and machining a new, heavier one and welding it back on in the right place.

Is this something people have done before?

I have had good results with simply plating the front side of the bracket with 1/4" steel welded on.

Hm, well that is definitely something I'll consider doing. Thanks for the help. :)

X2 for plating the bracket, I have seen multiple times where the lower trackbar bracket bolt hole has wallowed out and that can open a can of worms if you aren't prepared.

Hey cj7-tim, I noticed reading in some other threads that you run (or at least ran) a double shear TB. Is there any merit to me looking into that setup? IRO's website makes it sound pretty appealing, but I realize that they are just trying to sell me a track bar lol. I DD my Cherokee but I do some semi-serious off roading whenever I get the chance.

It seems like a really good price for such a complete set up.

I run the IRO double shear trackbar, and it's a very good option for a lifted vehicle.

The 0-5" has plenty of adjustment left where I sit ~5" and I can drive 75-80 mph w. ZERO DW.

I also run the IRO tie rod as the OEM is a toothpick compared to it - especially if you're running oversized tires.

I'm not an IRO fanboy, but I strongly endorse their trackbar setup.

CJ7-Tim 08-27-2013 11:15 AM

IRO is just across town. They make very good parts, and they 4wheel what they build. Their DS track bar is one of the best, and I recommend them for any lifted Jeep.

macklamar 08-27-2013 04:33 PM

Yea I think I'm gonna buy one of these this weekend...

macklamar 09-06-2013 06:47 PM

Just ordered one, as well as their steering stabilizer. Hoping to be able to put it on next weekend =)
