Default Unequal and low Caster

I’ve added a basic 50cm / 2inch lift on my Jeep JK 2 door not intending to do too much off-roading but more for the look and adventuring. Planning on slowly adding more suspension parts as it develops.

I have come back from the wheel alignment shop with the following report on my caster with the readings being unequal.

Front caster

left: -0*17
right: 1*34

Front camber

left: -0*46’
right: -0*37


Before I decide to add Lower control arms or relocation brackets I found the above result interesting and can’t find too much information on unequal caster. I’ve noticed that maybe the car has been slightly damaged on the left side, possibly hitting a ditch or off-roading, would the above reading indicate this?

What additional parts should I think about getting to amend the difference in caster?

That caster setting should be the cause of flighty steering but you are not complaining about that. Most Jeeps need +3.8 to +4.5 caster. I run about +5 which does make the steering a bit heavier but ok. Not much you can do about unequal caster except to use offset ball joints to correct. Personally in my book these things are not Ferarri's so I don't worry about unequal settings as 110-120kph is plenty. But you need to get it caster to what I say earlier here or get another shop to look as it is hard to believe it is factory at that setting even with the 2" lift.

The steering is very flighty and will address that with either relocation brackets or lower control arms. Before I do so I was just wondering if the unequal caster was a major issue and what would help get that in line.

If I am reading your caster numbers correctly the difference is less than 1 degree. Nothing to worry about just as Sixty4X4 has stated. More forward with adjustable control arms or relocation brackets or both ! you should get another alignment check after installation of these parts and that is the results to pay attention to. Caster is your friend , dial in more caster.

Thanks for the replies. I’ll be installing adjustable control arms as soon as I can!
