Well, the wife spotted it today, and I measured it out. The driver side of my jeep is 1.5" higher than the left side. I measured at multiple points front, middle, and back, and at the rear bumper its about 1". At the mid point and just behind front flare it is closer to 1.5".

I checked the springs and they all appear seated. I didn't measure each one, though I think I can, it is just 10:20 at night and dark, so I didn't try yet.

I have a 4" TF Long Arm. Nothing appears bent or broken. I went wheeling Sunday, and while we have only had the jeep about 2 weeks now (used '08), I don't recall it appearing uneven before the wheeling trip. All tires are aired up to about 37 psi, so I don't believe tires are an issue, especially with 1.5" difference, but I can measure it...

Any thoughts as to the cause?

 

You have a right hand drive JK?

 

Left hand drive.

 

you stated the driver side is higher than the left side

 

With a full tank of gas all JKs are lower on he passenger side I think.

 

Maybe check your sway bar disconnects if they are adjustable. That can contribute to one side lower than the other if the disconnects are not set at the same length.
But many JK's have a slight lean to the passenger side and front end typically slightly higher than rear

 

Yea, the driver side (looking at the jeep from the rear, the left side) is higher than the passenger side.

I do have a full tank of gas at the moment.

 

yea that means he has a lean to the passenger side

 

The tank is mounted on passenger side. I've read many posts on here that claim the lean is normal. That being said I've never really noticed it on my rig.

 

Just went out and checked, the sway bar disconnects are not adjustable. Also, its a Rubicon, so has a e-sway bar disconnect for actually doing the disconnecting, but figured you meant the rods themselves.
