I was reading a few posts on here that stated an alignment can be done with a tape measure. This is incorrect, you CAN NOT properly align anything with a tape measure.
While you may be able to set the front toe in/out, you can not index the front end geometery to the rear axle in this fashion. If you have ever been behind a vehicle which is "crabbing", setting only the front toe is the reason. All four wheels must be measured and aligned, I know that there is no adjustment in the rear, none the less this MUST be measured to ensure the axles are square to the vehicle and each other.
Spend the $100 and get it done properly.
Thank you for your time

Yeah I learned this the hard way. I installed a high steer kit. Just to be on the safe side I took it to the best jeep specialty shop around for a "proper" alignment. They charged me the $100 and then asked why the hell I brought it in since I was only off by about 1/16" at most. After getting my balls busted for thinking there was something mystical they were going to do I do them all myself now. Never pulls and drives pretty much perfect.

There are better ways to spend $100. The only thing the alignment shop will do is adjust the toe in and scratch their heads as to how to adjust the caster. There is nothing to adjust on the rear end - this isn't a coil suspension with adjustable control arms. Everything is self centering and self aligning when in proper condition.
If a YJ is crabbing you got damage to the suspension or to the frame, or both. There is no way on God's green Earth that an alignment shop will fix a "crabbing" problem on a leaf sprung YJ for a flat $100 fee, all potential parts and labor included.
I mean sure, if you aren't comfortable with a wrench you have to pay the premium to have an experienced person do the work for you. But there are many of us quite competent to be able to inspect a leaf sprung suspension to verify it is squared, and to be able to turn the tie rod with some vice grips to adjust the toe in.
And besides, that $100 is better spent towards some brews and good food that can be enjoyed after we get done doing our own repairs.
