Track Bar Adjustment

Hi All,
I have a 2012 JKU with a RockKrawler 3.5" Mid Arm Lift. My rear track bar has shifted and started rubbing my passenger side rear spring.

I've been told it only needs to be rotated upwards and away from the spring. So in the attached picture, I loosened the nuts on both sides (circled in red), and then loosened the nuts highlighted in orange. the nut on the drivers side was very loose, and I'm guessing that is what caused the issue. Seemed simple enough, but that sucker wasn't rotatable. Suggestions on what to do?

Thanks,

Badger2012.

What specifically has someone told you to rotate on the TB?

I thought they said to rotate the whole track bar away from the spring. Maybe I misunderstood.

Can you take a pic on the vehicle? I'm confused too.

Who gave you this advice? I'm under the impression the track bars should be close to parallel.

The rear track has bend in to avoid interference with the gear enclosure in the differential. It also is designed to lean towards the rear of the Jeep. The natural tendency of the track is to rotate to a vertical position when it is under load and you don't tighten the adjustment nuts. When it is in a vertical position it can rub against the coil when the suspension cycles.

First make sure it is rotated towards the back so the bend clears the diff enclosure at an angle then make sure everything is torqued properly. Who ever installed it the first time around didn't do a very good job.

That last one shows where the bar is rubbing on the spring. Does that help?

It's not only rubbing the spring it's also resting on the rear differential. That's bad news and means more is wrong.

While it does look like that ESP, it is about 1" away from the diff, and it doesn't look like it has scuffed it. I had to go out and take a look at it.

I just noticed that the 2nd photo above shows that the spring is bent at an odd angle. I'd forgotten about that.

Suggestions?

So the problem is it just won't rotate up ?

You said you loosened the nut but how much ? Maybe try loosening them a bit more and put a large pipe wrench on it to try and turn it up ?

Spinlock, I didn't see your response until just now.

Like I said, I undid all the bolts but it didn't seem to want to move. Do I need to really reef on it to get it to move?

Sixpack, missed your response as well. I thought I loosened them up really well, but I will retry, and maybe go buy a pipe wrench.

Thanks all!

From the pic, it looks like the track bar is contacting the diff. Resting right on top of it. Did you install Adj arms with the 3.5? If not that could explain why things look so close and why the TB is contacting the coil.

Both 3.5" mid arm lifts come with
Rear Track Bar Relocation Bracket.
-----------
I need to verify what lift I actually purchased. I thought I didn't get the x-Factor lift, but that is what I put in my list of mods. I still think that I decided it was too expensive.

The x-Factor lift says
"...high misalignment lower control arms front and rear, high misalignment upper adjustable control arms front and rear..."

The non x-Factor says
"include features like high clearance adjustable lower control arms, front sway bar disconnects, long travel linear coil springs and long travel stainless steel brake lines to just name a few."

Will try and make the call tomorrow.

Thanks,
Badger2012.

Yes .. You need to rotate the track bar bend out. That's part of the Benefit of the double adjustment. Loosen both jam nuts and rotate so the bend is facing the rear.


The X factor is complete with all 8 CA's including both track bars. Do you have all 8 adjustable CA's ? The flex kit in 3.5 includes only lowers and a front TB.

looks like the trac bar could be upside down?

How can it be "upside down"
The TB would have to be installed with the flax/rubber joint reversed.... Right ?
He needs to rotate it out like said a few times.

If you truly bought a mid arm lift your rear upper and lower control arms will be longer than stock. From your pictures this looks to be the case. A few things need to occur to fix your rear end. First...look to see if you received a track bar relocation bracket that moves the frame side track bar attachment point back 1". It more than likely mounts against the rearward side of the existing frame mount. If your upper and lower arms are an inch longer the track bar frame mount must move towards the rear to compensate for the extra length. Second...your swaybar must also move back towards the rear the same inch. This will now put the track and swaybar into their original relationship with your axle. Third...now that your axle is back an inch the coils are no longer in their original relationship. This can be compensated for by using coil wedges which will allow the coils to fit into the cups and have a flat surface to seat against. Once this is complete you can adjust you track bar to center your axle and then move onto adjusting your pinion angle. Hope this helps.

Can you get us a picture of your pinion angle? The bends in the rear track bar should be oriented so the track bar bends down right after the diferential then it bends back straight again to run into the track bar bracket.
