Default Axle pushed back?

So I've noticed that it seems that my front axle is being pulled backwards for some reason if that makes any sense.

I believe this is throwing my camber off because my from tires are also bowed inward slightly like this. \ /

I noticed this because upon looking at my front coils the appeared to be on an angle.

I have a 4.5 in RC lift with the lower control arms that came with the kit with stock uppers.

Any ideas?

Control arms and how far back the axle sits have nothing to do with camber or toe. It only affects castor.

Camber is affected by worn ball joints or if your axle is bent. Toe is the steering linkage.

Did you go for an alignment after you put the lift on? (something tells me no)

I didn't get an alignment done directly after I put the lift on but I had an alignment done when I got new tires.

I was thinking ball joints as well but they are new all around

New good ones or new cheap junk? What size tires and how long have they been in there?

Easy way to find out if the ball joints are to blame: Jack up the Jeep and see if the wheels wiggle up and down.

Use Moog parts and buy you some good adjustable upper and lower control arms. Then you can set where the axle sets in the wheel well and the ft. pinion angle.

The ball joints? They are moog I believe. Not sure if that is a good or bad.

Tires are only 31" and been on for about 1 1/2 - 2 months now.

I've done what you said with the wiggling and all is solid no movement.

I can post pics if that helps

Lifting with non adjustable arms will pull the axle back some. Odds are the alignment shop you got it done at set your tire to factory settings and not lift settings. Your castor can be adjusted with shims in the lca buckets or if your arms are adjustable you can lengthen or shorten them as needed

YTour upper arms are too short. Upper located the axle forward and back. lengthening and shortening the lowers ROTATES the axle changing the caster/pinion angle. The is some camber built into the axel and ROTATING the axel does also affect camber.. But not enoungh to matter, generally.

There is no camber built into these axles. Rotating does not effect camber. You're talking about caster.

salad is correct. Camber is not adjtstable. There is, however, an acceptable limit for positive or negative camber. I can't see where adjusting the caster is gonna have much, if any, affect on camber.

Oh I never said that... jump your Jeep enough times and I'm sure the camber will be adjusted

There are plenty of write ups on how to diy alignment. If you're uncomfortable with doing that take it to a 4x4 shop for alignment. I wouldn't worry about the axle being pulled back a little. I'm on about 4 inches lift up from with the stock arms still (I know, leave me alone about it, full width build in progress) and it drives fine. A little wandering but it's manageable

ok hate to steal the tread but I also have a problem with my 3" lifted 99 sport just rotated tires and now I am hitting the driver finder in the rear of it ... so I measured the wheel base and found pass=101.5 , driver=101" so do I need to move lca or uca to get the castor back. Also don't have adjustable arms
rotated tires do to bad coupling in the front but rears are fine
