Will this center axles?

I am planing on putting on a OME soon, and was wondering how to center it when I put adj. track bars front and rear.

Was wondering if I hang a plum line off the oil pan, frame, etc. to the axle and mark the axle at that point. Then, when I install the lift, all I would have to do is adj. the mark on the axle back up with the plum line hanging down and should be back at factory center! At least in my mine.

Well, does this sound like it will getr done?

That should do it, If you have a $15 laser level that would to it too. I recommend getting it aligned at a reputable shop post lift. Tires are too darn $$$$ to skip this step in an attempt to save $50-$60.

Just remember that when you center the axle the Jeep needs to be sitting on the ground with the suspension settled in its rolling form.
I tried to do mine by figuring the track-bar length mathematically then I ended up using my precision eyeball for the final adjustment

That's less precise than using a point on the frame and a consistent point on the axle.

Why? Fenders and tires are just as accurate as frame and axle, as long as your tires are the same size and your fenders are equal width. And, in all honesty you can only really get it good enough for government work by the time you get sick of adjusting the track bar a dozen times.

1. In order to set an adjustable front track bar, you will first need to determine how much your front axle is off by. To do this, firmly hold a carpenters level up against the sidewall of your driver side front tire making sure that it is aligned to the center of the wheel. Make sure that the bubble in the level is centered and then, using a tape measure, measure the distance between it and the edge of your fender flare (or other pre-determined point like the spring perch). If your level is making contact with a shoulder lug on your tire, be sure to make a note of it especially if the lugs are of different sizes or are located at different points along the edge of the tire and would influence your measurement. Repeat the process on the passenger side of your Jeep (again being aware of the shoulder lugs and how they might influence your measurements) and then calculate the difference between the two sides.

I like my ideal better, seems much easier. And then yes, will get it aligned.

This is one of those things where close is close enough!
Just remember that no matter how perfectly centered the axles are to start with they will be off center in opposite directions as soon as you add any weight to the vehicle. This could be fuel, passengers, groceries, mud, etc.
If you center with a full tank of gas and a driver and one passenger in the front seat then this will be the only configuration in which it will be centered.
The best you could do would be to center them for the average load that you will be driving with.

For the rear I used a sharpie marker and marked the center of the frame and center of the axle then used a plumb bob to get them lined up. For the front I made a tool to hang a plumb bob from above the engine compartment. Here is a link to the post I did when I built it. I hope it helps.

Dirtman, I have not looked yet what I can hang a plum off on the front yet, but that will give me options when I get to that point!
