Tires rubbing on new control arms.

^^^^^^^
What he said. Also the sway bar links seem to shift towards the driver side at the bottom (especially the driver side).

Agree. But moving the axle slightly more towards passenger would make the tire rub more wouldn't it?

@sass JT already nailed it above and the JL guys figured this out long ago... 4.5" of backspacing on the narrow, non max-tow sport axles is too much to run a 40" tire for exactly this reason. 40s look great and fit with minimal work but it's threading a fine needle on these trucks to do it functionally.

You might find other control arms with a greater bend but I think what you'll have to do is go with spacers or a wheel with no more than a 3.5" backspace. Even then you might have issues because the more common setup going this large is the wide Rubi axle that pushes you out .75" per side in a way that cannot be compensated for on the narrower axle.

Which is how you know it's not the axle centering. People will judge it based on two pictures on the internet when I saw many trained professionals who couldn't eyeball it to a half inch in the bay. May be right, and probably worth checking at some point, but it's not the cause of what you're dealing with.

I don't know that it will be able to completely fix your rub, but your axle really looks like it's shifted to the driver side pretty significantly. I believe it would actually help as the control arms would be more straight in line with truck and not pushed towards the driver side .

I started to add to my previous comment that you'll likely need the spacers anyway, otherwise there is a video () that show adjusting the steering stops. If you can minimize the rubbing by properly adjusting the axle spacing, then you might get a way with a small adjustment to the steering stops.

As said earlier, definitely adjust track bar. That will tell you how bad it is. Steering stop would be my next step and then maybe look into alternative control arms. You will hear varied opinions but mine is make the wheel spacers a last resort, especially with the tire and wheel combo.

Thanks everyone. Will do a check to see the axle alignment this evening. Makes sense it could help straighten the CAs. Then adjust the steering locks.

Overall I havent rubbed since I noticed it but I've been cautious. Can still make normal turns on roads and in parking lots. Now a tight 3 point turn would be a different story.
