Also, Any chance one of the spherical bushings in the lower control arms is loose? Maybe didn't get assembled correctly at the vendor? Mistakes do happen.

 

Double check the installation of your rear track bar. I could be wrong, but to me it looks like the frame end of the track bar is installed upside down. That might be why the shake starts in the rear. Also make sure the jam nuts are tight. HTH.

 

I have a different frt adj trk bar, so I don't know for sure if the bend in it where it attaches to the axl should go like you have it, bending down, or be more level such as turning it over, maybe someone else with this kit or trk bar can look at theirs.

 

Just checked JKS installation instructions on their website. Looks like he has it right. Sorrry for the confusion.

Here is a front view of that same spring.

 

Not sure if this has been mentioned yet but see if you can move your adj front trackbar on the frame side at all. Teraflex was helpful to me saying the stock trackbar mounts are pretty thin on these JK's and you may need reinforcement to true it up. Your front trackbar mount hole could be a bit oblong, might check that too.

 

Anybody know if that bend in the frt adj control arm where it adjusts is right? Looks like it should be rotated over, the gold part.

 

I just sent you a PM,

Couple of questions, what are you running for tire pressures and do you know you toe in numbers?

As several have mentioned the front track bar is always a suspect. I had to go to nearly 150lbs on mine to keep it from moving eventhough 125lb was spec. Since you haven't put much castor back in a combo of that high tire pressures and bad toe could be a group of several things instead of a single silver bullit issue.

Good Luck

 

I guess the Jeep g-ds have decided to keep me up all night long or something. I am going to try to answer all the questions that you have asked and sum up a few things in the process.

wiredawg_mg: The tire pressure is set at 33 psi and the toe has not be changed since the factory. The toe could be a factor to this problem but since I have not changed out the wheels or the tires and the toe bar was not touched in the process of the lift, this prolly is not the issue. Great suggestion

Also, I have torqued the front and rear trackbars to 125 but I can go out there this evening and re-torque them to 150 if need be. Great suggestion

mkjeep: If you look at the JKS instructions the bend in the front control arm is normal and it is in the correct position. Great suggestion

rogu3JK: As of this evening, I could not move the trackbar mounts. When I re-torque the front trackbar, I will take it off and check for oblong holes. Great suggestion

Tank and bOLsAK=3: The alignment is the next thing on my list of many things to do. The Jeep ran down the road straight before the lift and still runs straight even during the earthquake (TOAD). Missouri does not get to many earthquakes but the few that we have had, this is worse than any of them. Great suggestion

chip80: If the Jeep g-ds tell me to rotate the spring, I will do so. It looks like it is seated on the bottom bracket since there are no spring perches here. Great suggestion

jpp: The jam nut is tight, it just has a lot of anti-seeze on it. Great suggestion

RedneckJeep: Thanks for the advise and the great suggestion

• Re-cap, I have taken the rear trackbar bracket off, still not fixed.
• I have re-torqued everything to 125, still not fixed.
• I have taken off the wheel spacers, still not fixed.
• I have also moved the rear swaybar links to int inside of the swaybar because after taking off the wheel spaces they knocked off my wheel weights, still nothing. Good thing I had an extra set of wheels and tires.

After all the changes the jeep sits on its factory tire and wheel, no wheel spaces, front and rear trackbars aligned and torqued, control arms torqued, front lowers set at 23 1/8" and rear uppers set at 18 3/8"; the problem still persists. It does seem to start and stay on the passenger side.

Thanks for the great advise and the hard work.
