They aren’t always the same length, but they shouldn’t be different when it comes to axle position. The majority of the uppers job is to set the pinion angle (angle of the yoke). Since Jeep isn’t precise in the mounts, what’s important is that the axle is the same distance from the rear bolt of the skid plate on on both sides. Then you can check that the rotation is the same by measuring from upper axle mount to the frame on both sides. Control arm length isn’t the important part here, the axle is.
Good point, I had the skid plate off yesterday to clean up some surface rust and repaint and I didn't notice it then. Thats when I spotted the difference in the upper control arms.
Are the OEM skid bolts still available? I had one that had some rust corrosion I didn't like, it torqued down fine but would replace it if available.
Only valid for 97-02. 03-06 are symmetrical.
mrblaine, question on the skid plate bolts, I used anti-seize when re-installing, should I have reduced the torque from 55 ft.lbs.? I know there are different thoughts on this process.
Generally yes. If they are the early ones, don't worry as much since the conical seat adds friction unless you slathered that as well.
I measured from the center of the control arm bolt to the center of the axle housing and both sides were the same even though the control arms are 3/8" difference.
