Ok I posted my problem once but wasnt completely correct with my information. It is the bracket that the track bar connects to the frame with, not the control arm like I stated earlier...my bad yall... kinda new to the mechanical world... Anyway, my problem is my backspacing from my rims is 4.75" and my rancho lift recomends a 4.5". All of these parts were ordered and installed(not by me)while I was overseas...Shitty part is its not the lift or the wheels I asked for. The sales rep talked my father into the crap I got... anyway... I am getting the death wobble... severely.. you can see a lot of unwanted movement back an forth if you watch the trac-arm while someone turns the wheels left to right...

My solution that is in the process.. (I am waiting on the parts) is an adjustable trac-bar by JKS, and removing the bracket from the equation all together... installing the new trac-bar and connecting it to the factory location. Now, to keep the steering angle correct and the drag link and trac-bar parrallel, I am going to remove the drop pitman arm and re-install the factory arm. I have not began with this, I want feedback from the experts!! YOU GUYS... Do you all think this will correct my issue? and if not what will??? I need my vehicle back on the road... and I am on a budget :(

 

We had those issues but on the lower mount versus the frame (video shows). Since we wanted to take care of a couple of things like the weak frame we went with a TeraFlex Drag Link Flip kit and HD Frame brace. In addition we had ORE weld up a new lower bracket which is super thick and added a TeraFlex Monster Front Track Bar. Since the DW is a symptom of something else we had to identify the root cause and in our case it was the upper ctrl arm (oem) bushings where shot so we replaced them with the Currie Johnny Joints. In your case it looks like you need some wheel spacers from what you describe. We had something like that as well going from our first lift to the coil overs so we put on some spidertrax and problem solved. Good luck at least you identified the issue which is sometimes the toughest part.

I have the Rancho Sport lift. The only problem I had with it was the lowered stock track bar hitting my G2 Diff Cover in the front and preventing articulation on the driver side. It was obviously designed to only work with factory diff covers.

I replaced the drop bracket and factory track bar with an adjustable Teraflex bar. I also removed the drop pitman. It drives fine ... but definitely rode better on the steet with the drop pitman and drop bracket.

Ultimately the best thing to do will be to go with the AEV HIGH Steer kit which should work really well with the Rancho lift.

 

I forgot to add... I am replacing the front lower control arms as well, just incase the bushings are shot in the current arms... I am just hoping my idea fixes the problem... If it does not I am not sure what I will do. I would have considered some of the other steering kits and possibilities but my budget is not in the shape for all that until I know it will work for sure...

Wheel spacers? That would cause my tires to stick out even farther... and the current backspacing is a quarter more then recommended... Wouldnt that put more pressure on my suspension and steering ???? Shouldnt I be trying to get less pressure? I thought that was what was causing my issue..?

 

Actually your backspacing is .25" LESS than recommended. a 4.5" Backspace sticks out further than 4.75" backspace. That won't cause DW though ... it will cause rubbing.

If you are torquing your track bar bolts to 130 ft/lbs and the bar is still moving just by turning the wheels ... I have no idea what the problem could be. Even if the holes a wallowed out it won't move that easy if torqued to spec.

Is the Rancho Drop Bracket also Torqued down properly?? It should be rock solid .... there should be 3 bolts holding it in. Two of the bolts were a real pain in the ass so hopefully the install shop didn't just leave them off!! Can you post a picture of the Rancho Drop Bracket and how it's bolted on ?

 

You probably won't even notice the difference too much but it will definitely correct for BS issues. I don't think it's the root cause, it would cause rubbing which was the case for me the brake lines got messed up because they rubbed under certain articulation. As for stress I don't think the amount it adjust for actually does any harm but maybe someone who has run them for a long period of time and had a failure could chime in. I've run them for a year without issues.

 

here is a pic of the old bracket... (I know it was in bad shape..... there were a few real slight cracks in the old one which definitely altowed more articulation then desired...)I have a brand new one installed right now, torqued to spec...I am still getting a slight wobble... not a complete all out death wobble like before, so I know the new bracket helped... but I want it to be gone!!! The wobble doesnt happen all the time, it seems to come completely randomly, not caused by bumps in the road, certain speeds, or anything I can feel that may push it into the wobbleing motion, but when I turn the steering wheel left or right as the road curves it seems that the turn puts the steering setup in the correct line and the wobble goes away ... and then comes back when it feels like it... I dont necessarily have to turn for it to go away either... it just comes and leaves as it pleases...

Could this be a bad steering dampener as well, could the intensity of the wobble before this new bracket damaged any other of the steering components...?

 

Looks like you have a drop bracket and a drop pitman arm?

 

I don't think a bad steering dampener would cause the wobble; if anything, replacing the steering dampener might mask the real issue.

Not sure if this was brought up before, but when was the last time you had your tires balanced? One or more tires off balance can contribute to the slight wobble you indicated. Also, have you had a alignment done?

 

the tires have been balanced and a fresh alignment both done in the last month... we all thought that was the problem as well, after the alignment and rebalance the wobble remains... and we sit stumped...
