Did you install a lift?
Why does the wheel in the bottom picture look like it's not straight?

From the pic, I’d say yes. But it’d be best to place a straight edge up against the tire and measure to the flare to be sure.

Get a yardstick or a piece of wood and hold it up against the tire. Measure from the spring bucket or frame and check it. Need to? Probably not. If it bugs you then do it.
I did and it’s 1/4 inch shorter on passenger side.

Like they said, use a straight edge. It's not easy to tell if you are looking totally straight down - 90 degrees - both times.

Me - I like 'em centered. Then the push is totally straight ahead, but I'm a bit OCD.
I guess what's the point of an adjustable track bar if you aren't going to dial it in.

It still looks to me like the tire in the bottom photo isn't pointing straight ahead while the top pic it is.

That makes sense as the axle shifts left as you lift the truck and the track bar swings down on the right.

Then you'll only be moving it 1/8".
I like things straight, and like I said - what's the point of the adjustable track bar if not to center things after a lift.

Others it might not bother and they'd say it's not worth getting under the truck for.

He did measure, it's 1/4" so it's off 1/8"

Makes sense as mine is off nearly that far. I can see it.

You got yourself a fancy set of calibrated eyeballs?

Which reminds me, the over first half of this year I add a handful of HEAVY accessories. I may take a look tomorrow morning and see if my axles have shifted.

Seriously, you can't see a 1/4" difference? You have perspective when looking straight down because of the tread, even looking from the front, you have perspective - sight up from the tire.

I put the Rubicon springs under the front and saw right away something wasn't right. I look at the left, then the right, then the left again - hmmm, only 1" and that much shift? Sure enough..... a straight edge and measure over and it was 1/4" more on the left than the right.
Yeah, you can see 1/4" difference.
His is off 1/4" and I could see it from his photos. I did question whether his angle was the same on both sides as far as camera angle as if you are off a little, it skews it, but yes, you can see 1/4" difference pretty easily.

It bugs me because the more off-center the front axle is, the more angle there is on the control arm bushings and uneven push, and every bump ,means the axle moves more than it would normally due to the arc swing of the track bar.

If I do a lift on my next one, it will have an adjustable track bar. (that would also put the steering wheel back in center to some extent)

Check your inbox.
Rule #1 - Never measure off the tires. Inconsistencies in mfg tend to create unequal tires.
Rule #2 - Check the wheels.

The best method is to find vehicle centerline (based on frame rails), and measure from the face of the hub to the vehicle centerline.

But all things being equal, and the simplest explanation is usually the correct one, if this happened post-lift, the rear end needs to be moved via trackbar.
