Classic2000

Hi all,
I searched and couldn't find anything on this. Please share if you know any threads. I have a 2000 xj, 6 inch long arm lift, 33 inch tires. 4wd. I'm working on my alignment and decided to check the wheelbase. Turns out the wheelbase is 1 inch shorter on the driver's side vs the passenger side. Is this normal or is this a concern?? The alignment seems off while driving. I double checked control arms and they are equal lengths and both tires seem to be centered in the fenders. Any thoughts?

Thanks

Have never had long arms, but it sounds like the frame brackets were installed incorrectly. Take you "wheelbase" measurement to the centerbolt of the arm bushing at the frame mount. But wouldn't that leave the spring mount on the axle not perpendicular to the spring seat on the frame

That's definitely an issue if its true. Not detrimental, but I'd certainly want it corrected.

Are you sure its in the front axle? Is the thrust angle of the rear axle off?

The thing with alignments is it really doesn't matter where the mounts are, how long the arms are, etc, what matters is the tires are positioned exactly where they need to be.

I know everyone loves to do their own tape measure alignments, but I'm an advocate for getting a professional alignment done by a 4wd shop. They can align the front axle parallel and centered with respect to the rear axle much more precisely than can be done without the proper equipment.

I do my own alignment action. I put 4 pads in my dirt yard, all level to each other. Got an alignment level (roundy round racecar supplier). Made a toe bar( 20mm stock w/ Allen screws each end). Tape measure and off ya go. It isn't that difficult. I corrected a 1/4" off square condition front to back. Then set toe in. Check caster angle. All done! Go for it bro, you can then be "that guy" who can align a ride👍

From your old posts you seem to have a 4.5 inch lift, so I assume you have aftermarket springs. Is the rear axle properly centered & seated on the leafs?
