Somethings just not right with my alignment...

I purchased my XJ as a 2WD Jeep with a 5.5" Lift. I have since converted it to 4WD and have been plagued with vibes since then.

My issue is specifically with the front end, I have done multiple alignments (both at home, and at a shop) and one of my front wheels just doesn't look right to me.

My drivers side wheel looks like it is turned outward in comparison to the passenger side wheel. I have checked my toe over and over, with the tape measure method and the numbers show 0*. To rule out differences in tire sidewall bulge I even put a set of tireless Rubicon wheels on the front end and measured outer rim to outer rim (measured 64 5/8" across, front and back of rim). Even with the tireless rims the left wheel looked turned out in comparison with the passenger side.

The drivers side wheel still seems turned out to me, is this possible even though my measurements shows 0* of Toe???

I did not experience this with the original straight tube axle it come with, both wheels pointed "straight" and rode great. (same set of tires/wheels by the way).

Things I have done to date:
  • Replaced Trackbar bushing, and TRE
  • Replaced Steering Dampner
  • Replaced entire front steering linkage with RR setup
  • new rotors (pads and calipers as well)
  • replaced front axles with new units

Is it a D30 axle? Is it possible the tubes are bent, knocking one wheel out of whack? With all the work you have done, that would be my last guess!

I hope you track down the issue!

Yes, its a D30...if the tubes were bent would I still get equal measurements on the front and rear of the wheels when checking toe?

Short arm lift or long arm lift ? If short arm, drop brackets ?

Any issues with odd tire wear or weird steering ?

What do your front and rear pinion angles look like ? Have an SYE ?

Pulled the front drive shaft and gone for a test drive ? The rear ?

Short arm kit, no drop brackets, inner part of tire wearing faster than outside, and "loose" steering. TC drop installed, rear vibes are minimal. No SYE yet, 231 currently on the bench being rebuilt and a AA SYE going in it. Riding with front DS has no affect (positive or negtive) on issue at hand. That drivers wheel is driving me crazy because it is obviously off upon visual inspection but measurements says its fine.

Vibes, wear, and steering issues started after going 4WD.

Suspect the ball joints for the tire wear. Because the lift rotates the axle, the caster is off, and you can sometimes see this.

Vibes could be the drive shaft itself or from bad pinion angles, especially the front axle.

Thanks for the lead, I will replace the ball joints, and the axle control arm bushings just to be safe. Will report back with my results.

With the wheels streight, measure from the back of the rear wheels to the back of the front wheels. The driver side should be about 1/2 inch or so less than passenger side.
