New Lift Suspension Issues

I recently installed a 1.5" Superlift Super Ride suspension lift on my YJ and the springs are now biased to the driver's side of the Jeep. My first inclination was to remove the track bar, but when I loosened the nut on the driver's side of the bar I was able to free-spin the bolt which is telling me that the track bar is in a no-load condition and not the reason for the bias condition. Does anyone have any input on this that may be helpful? For back ground info, I purchased the Jeep 4 years ago from the original owner with just 28K original miles on it and has never been driven in the rain, let alone off road, and never in an accident. All bolts are torqued to 95 lbs/ft as per the maintenance manual and it seems to handle o.k. I'm of the impression that maybe I need to drive it around a bit to settle the suspension, but am out of Schlitz at this point from a troubleshooting perspective...

Have you checked to see if the front spring hanger mounts have developed cracks along the frame anywhere?

Is there any evidence that any of those same mounts have ever been repaired/rewelded etc?

i see your track bar is still connected, as you have pointed out

take it off. that should settle it some. You've changed the geometry of your jeep suspension now... you either need an extension bracket on that track bar... or the better and cheaper option is to throw it out. It's not needed and will make your jeep ride harsh.

Despite you pointing out that you could free spin the bolt - just take it off and drive the jeep a bit and settle the suspension.

Stop whining about the 'ride' - If your YJ ain't wrangling your soul free, then might I suggest you buy a stationwagon... at least you can fit all your bull**** in the back.

from the picture it looks like the inner tubes are too long or the shoulders on the bushings too thin

Your shackles also look bent now so you may want to replace them. I have a brand new in the box set of stock shackles. I dont know what your back looks like but I have enought to replace the front. They are crown. THey dont have bushings anymore I used them but you have new bushings so you should be alright.

1995 YJ. 2 inch BDS Spring lift. 1 inch shackle lift. 1.25 inch JKS Body Lift 33x12.5x15's. Engo 10,000 pound winch.

Joe Dillard, bruinjeeper, jbolty, Siva283...thank you all for the input. Spring mounts are good to go, and I think the shackles and bolt sleeves are all o.k. and to specs. I'll look into the track bar as that's really the only component that would cause the bias and see where I end up...thanks again for having my back on this, I appreciate it...AIRPOWER!!!

It just looks like the shackles are leaning.

Both are unnecessary

I don't know how much difference it would make (probably none) but your u-bolts are on all wonky as well.

Make sure the springs are in the right direction, they have a front and a rear. also there are front and rear springs they are not all 4 identical in all sets of springs, the locator pins are about a inch forward.

Copy all...I pulled the front track bar and the bias appears to be less. I'm getting it aligned today as the steering wheel vertical is now sitting at the 7 o'clock position. The u-bolts are seated properly... the inboard u-bolts are wider and longer than the outboards and sit on a "perch" close to the pumpkin that gives the appearance that they are misaligned when in actuality, they're good to go. Thanks again for all of the input, I appreciate it!
