Confused, please help.
 
So i had teraflex 2.5" coil lift and 35" tires recently put on 2013 jku by local 4 wheel parts. Just today, i noticed that tires are not centered. To be exact, driver side of the vehicle's tires are an inch out than the passenger side, both front and rear tires.
Looks like the whole car needs to be moved to the right for an inch.
We did the same set up with my cousins car and i checked his and it was centered. Should i take it back to the shop? Is it an alignment or what?

back to the shop.

Did you need to put in wheel spacers? could be that.

I don't think so, they were after market wheels with 4.5" backspace

The axle shifts front driver and rear passenger after a lift.

Do you have adjustable track bars adjusted wrong ?

Pardon my ignorance, but i don't know. Its my first wrangler, just had the shop mess with my lift. They did good job with a first car( for my cousin), so i went with them too.

Moonrider 06-18-2013 11:52 PM

They actually also recommend that i bring it back after 500 miles for check up when the initial work was submited

The track bars (pic)
Look at yours and see if there is any kind of adjustment on them. Stock will not.

Rooster76 06-19-2013 07:45 AM

Im not a lift expert, but have spent a good amount of time researching lifts. This is what I think is the deal. Your track bars (front and rear) is what centers the axle. You got the basic 2.5" coil lift. It comes with a bracket to adjust the track bar position in the rear. It doesn't address the front trackbar for whatever reason. Your close to stock weight, I'm assuming, without an aftermarket bumper, winch, and skids. Most kits give a bit more lift than advertised assuming people getting the lift will have added some of those items. With the extra lift added it slid your axle most likely more in the front over to the driver side. Though you say it went to the right on both axles??? In the back a lift with the stock track bar would push it to the passenger side as explained earlier.

THE INSTALLERS CANNOT ADJUST MUCH
Unless you kit came with an adjustable trackbar or two, its likely all they can do is center the steering wheel.

DO YOU HAVE AN ADJUSTABLE REAR TRACK BAR?(DOUBT IT)
What I would do is locate the rear trackbar. It will connect to the frame on the passenger side and axle on the driver side. Does the track bar look like it is adjustable or is it just a solid hunk of metal. If you know the parts on the lift it would say adjustable rear trackbar. If so take it back and have it adjusted.

IS THE CORRECTIVE BRACKET INSTALLED.
Im assuming it just has the corrective bracket. It will look like a bolted on part that moves the track bar a couple inches down. Check 2.14 of this video. http://www.youtube.com/watch?v=vz-R5E-NPQg

TRACKBAR SOLUTION
If you have neither of those the installer is to blame. If you do have a bracket it could be switched with an adjustable trackbar for more fine tuning. Those are about $250 per axle.

CONTROL ARMS
If it is an issue created by too much lift you may want to consider adding AEV lower control arm (LCA) brackets if driving around seems a bit flighty. They are about $100. They drop the frame mount location a couple inches. That's not ideal for off roading. The other option is adjustable LCAs that are more expensive, but better solution.

EXHAUST HITTING DRIVELINE ISSUE
If you have a 2012+ jk you should have also gotten a teraflex exhaust spacer$50, or an aEf y-pipe(I'm pretty sure that the only 2options to correct the issue). Otherwise your front driveline will rub the boot leading to it ripping. See if those are on your receipts. If not get one of them installed. Here is a video showing the issue. http://youtu.be/s2CQD68LHSg

35"
With 35" tires you will likely want to reinforce your "Cs" on the end of the axles. Also if your using the stock spare carrier it will eventually break the welds with the extra weight. You can get an aftermarket carrier, or teraflex makes a reinforcement option.

You don't NEED adjustable Trackbars for a small lift.

BUT, if you want your axles PERFECTLY centered under the Jeep you do need a adjustable trackbar.

Maybe do a Front Adjustable TB and the rear TB later? The rear is more easily handled with a bracket but the rear tends to track good regardless of how centered it is.

blackntan 06-19-2013 08:28 PM

I've got the same lift and the same situation. Somehow both axles shifted toward drivers side, not a lot but enough to get on my nerves when I look at it closely. Just got my JKS adjustable track bars and will be installing this weekend which should take care of it.

Yeah, its not that much but up close it bothers me. So today, on a daylight, i measured everything again, and it looks like if the car needs to be moved to the left(driver side) by 3/8". I don't really want to spend extra money just to fix it. I don't understand why exact the same car with the same set up come out perfect without additional trackbars, or am i missing anything?

The first car we did was 2.5" Rubicon Express coil lift with monotube shocks which came out fine,

Then mine i chose 2.5" Teraflex coil lift with bilstein 5100 shocks. Both vehicles have exact same wheels and tires.

Welcome to the forum, I'm glad you found us here. There is a saying around here though - a kitten is killed every time you call a Jeep a car.

Lusus_Naturae 06-19-2013 11:13 PM

Now, to address your axle issue, you may need to get an adjustable track bar. The track bar holds to axle centered underneath the Jeep, but when you lift it, the stock one can't adjust a lot and what it thinks is the center, is off to the side now. An adjustable track bar will allow all the connection points to be centered with the new coil spring height, bringing your axle back underneath the Jeep evenly on both sides.

It's possible the lift height is a bit different in real life. Have you been able to sit the two Jeeps side by side?

It's also possible there are a few differences if the kits, or just the people installing it.

Thanks for the feedback, i actually put the both jeeps together today and even measured both heights, it looked like front of my jeep in higher by 3/4" than the other. Also, front drivers side is 1/2" or more higher than passengers side. I actually noticed unevenness from hoods line from inside by driving, first i though its a nonsense, and then i proved it right after i took a measuring tape.

The spring rates might be slightly different between your cousin's Rubicon Express lift and your Teraflex lift as they're different companies using different manufacturers most likely. As you say yours is lifted higher up front than your cousin's thus pushing the axle further out.

Your solution is an adjustable track bar as has been stated to correct the geometry. If you want to get one and want to stick with Teraflex they make one called the "JK Monster Front Forged Adjustabe Trackbar"

This video talks about the off-center axle a bit.

Very helpful man, thanks a lot.

One question, do i need just one front track bar to center front and rear axels, or i need a rear one too if there is one?

Front bar for the front axle an rear bar for the rear axle so you would need both

bearman95 06-20-2013 12:15 PM

Fours Wheel parts did the exact same lift on mine except they added a heavy duty steering stabilizer and a JKS adjustable front track bar. It been on for a just about a year with out any problems and everything is lined up like it should be. Take it back to the shop.

kjeeper10 06-20-2013 01:41 PM

You can do a front TB and a rear axle side TB bracket. The bracket will do 2 things
- center the axle (not perfectly but close)
- roll center

Teraflex offers a rear bracket with 3 holes at different heights.

Moonrider 06-20-2013 04:40 PM

Thanks everyone for support.

So i went to the shop today and they said the same thing- i need an adjustable track bars which will cost me $220 for labor only and another $350 for a set of two.
Now my question is should i do it myself or can i do it myself? Id like to learn more about my jeep, but in the same time i dont want to mess up anything either.

What track bars you going with ?

The Teraflex monster track bar or Synergy can be adjusted on the jeep. For the front -
- remove stock
- install new
- center body over axle
- may have to adjust drag link (steering wheel)

Both TB's are done with tires on the ground.

I haven't decided on a brand yet, but obviously only teraflex monster front trackbar cost $260 or so. At the shop they showed me one called Wrangler JK Adjustable trackbar and they offered $160 for that(front).
But it seems rear axle needs more adjustment than front. I dont know if i should do just rear one now or both at the same time?
Also, teraflex has rear TB bracket, should i do the bracket in the rear or track bar?

Moonrider 06-20-2013 05:13 PM

I dont know what to say to Teraflex 2.5 lift now. They cal lift kit and dont include adjustable brackets either. They should educate or add to the lift those components because if i knew this from beginning i would prolly go with rubi express which comes with everything for cheaper price and the ride feels smoother with their monotube shocks than with bilsteins 5100.
Im kinda dissapointed right now since nobody says or warns about axle shifting until its too late, not i need to spend another $500+ just to shift the axels.

Sorry Rubicon Express 2.5 lift that i didnt chose you.

The axles should only be "off" 3/8's or so at 2.5"
You might have some binding going on if the install was done incorrectly.

My RK coils have me 3.5" and I don't need a rear adjustable TB. I have one but i don't "need" it. The bracket is good enough to center the axle, more importantly raise roll center.

Your lift should have a bracket, either axle side or frame side for the rear ?

kjeeper10 06-20-2013 05:32 PM

My rear axle was actually over corrected using the upper hole in my TF bracket. I could of used the bottom hole but my front Tb Is Raised too.

Its best to have the roll centers match or higher in the rear.

Okay, i have very similar bracket in the same spot. Is this an adjustable bracket? Can this be adjusted to center the rear axel? When i spoke to the shop salesguy he said teraflex does not include brackets.
