Axel Offset

Recently put a lift on my Jeep and it is pushing my axel 3/4" to the passenger side. Is this normal for TJ's?? According to Rubicon Express it is. Just wanted other opinions.

I had the same issue with mine. I replaced the stock trackbar with an adjustable track bar and all is well now

The trackbar is connected to the frame and the axle. Any change in suspension height will cause the track bar to pull/push the axle one way or the other. This is a normal consiquence from a lift. Does it need to be corrected? No, unless it is causing anything to rub. It will not affect driveability or tire wear. The rear is easly corrected with a relocation bracket. The front will cost more with an adjustable bar. Redrilling the stock bar axle mount is an option but some do not like that because the hole can tear.

When I talked to Rubicon, They said that it would be pointless to get the adjustable track arm. Since when you use that, it still needs to be off set to 3/4" to the passenger side. This will allow enough swing in the axel and wont rip the inside of the tires. It sounded really well but just doesn't seem right.

But Neil F...Your saying that it is ok to have the offset and not to worry about it? Even if I do mainly road driving.

What would rip the inside of the tires? As far as it being pointless, I would think the whole reasoning behind it being adjustable is so you can adjust it to the correct length to square everything back up.

Yes it is fine. I asked this exact question a couple weeks ago as i have always been unsure. According to Jerry Bransford and others, it is fine unless it visually bothers you enough. There are no consiquences (again unless depending on wheel offset, rubbing occurs)

As for the ripping of the tires...They were saying that Jeeps have a swing axel in the back for mudding and such. But from the sounds of it that if I do center the axel and hit something the axel swings to the driver side door and can puncture the inside of the wheel. It can also mess up parts thats were attached and get them to rub the tires.

I was thinking the same thing...Im still trying to figure out how tires are going to get slashed by putting in an adjustable track bar if he chooses to do so

He said that Jeep axels are ment to move left and right. Since most people get Jeeps to go mudding and rock climbing. The axel allows this to happen more easily. I am not going to lie. When the guy was telling me I was totally lost.

Jeep axles move left/right as the suspension moves up and down. The axles do not move left/right unless the suspension (axle) moves up and down. For example... the rear suspension's track bar extends from the driver's side axle housing to the passenger-side frame mount. The track bar will push the rear axle towards the driver's side as the axle moves down and it will move the axle towards the passenger side as the axle moves up. The front axle moves opposite to that due to the front track bar extending from the passenger-side axle mount up to the driver's side frame mount.

Think of the letter 'Z' with the top horizontal line of the Z being the Jeep frame, the diagonal line being the track bar, and the lower horizontal line being the axle. If you pull down on the lower horizontal line (the axle), that diagonal line (the track bar) is going to pull the axle towards the right.

But so long as the axle isn't moving up or down, the axle is prevented from moving left/right by that track bar which is what positions the axle under the frame left-to-right.

That makes more sense then what Rubicon told me. For me personally the 3/4" to the passenger side is a sore eye. Along with when I slow down I can ffel the back end pull to the right. I would loved to center the axel, but don't know if it will mess anything up.

"ffel"? The rear axle can be recentered with either a trackbar relocation bracket or an adjustable length track bar. The only good way to do that up front though is with an adjustable length track bar.

Recentering the axle won't mess anything up. Running with it 3/4" to the side won't hurt anything either.

Feel*** Sorry typo. But I am thinking about getting the adjustable track bar for the rear to center the axel.

Only Jerry could explain an axle set up with the letter "Z." Thats a cool way to look at it

Called for another opinion about the axel off center. Jerry you pretty much nailed it on the head explaining it. So basically, TJ Jeeps are suppose to have the axle to the passenger side door on every day driving.

No. The axle is not "supposed" to be off center. It is pretty much centered in stock configuration. As Jerry and I have indicated, 3/4" off IS NOT GOING TO HURT ANYTHING.

The recommendation for the rear is a relocation bracket. It will only cost 20.00 and will do the job. The front requires an adjustable bar which will cost around 100.00 +/-

Come on without really eyeballing straight down the fender, you are not going to see 3/4" difference. The axle being 3/4" off to one side is not going to cause the vehicle to pull one way or another.
