Lower control arm install, something moved

This is my first time replacing control arms.

I got the drivers side out, I noticed something moved while removing it. Now I can't put the new one back, the holes are half an inch off.
What can I do to align?

Use a floor jack under the axle to raise/ lower it. That will align the bolt holes.

I jacked up the coil mount and that did it for me.

I only have my stock bottle jack, will that do if I jack it up in the center?

What exactly am I trying to adjust here, the left front axle?

The coil mount is what the coil sits on, or spring if that's what you call it.

I prefer the stock bottle jack personally. Don't jack it up with the differential.

When I was reinstalling my driver's side lower control arm I put the jack under the coil/spring mount to push the axle forward.

If that doesn't work, jack up the body and that will also push the axle forward.

The drivers side lined up after raising the body.

Now, the right side is not lining up. Tried jacking the body, right then left axle, no luck. It is almost an inch off.
How do I line right side now?

When doing my rear control arms I had to use a ratchet strap to realign one side.

Like I wrote, use the floor jack/ bottle jack method. Ratchet strap will just make you go crazy.

You are trying to lower or lift the front axle enough to line up the axle bracket and CA holes. Install the CA first @ the frame bracket and finger tighten. Then move the axle up/ down for the other holes to match. You may need to use the jack at either end of the axle to make it work.

As someone already pointed out, one option is to use the bottle jack under the coil spring pads, or under pinion so you can rotate the axle housing. Once you get it what you're trying to achieve, I guarantee it won't take more than a couple minutes to install the CA

Thank you all for the input, much appreciated.

Just finished, took about 8 hours. Jacking frame, turning wheel to complete left did the trick for the right side. Installed stock sway bar links as well. Now quarter mile drive for alignment. :-)

Next time if you need to replace CAs, jack up the front (or rear) fairly high to give you some spare room, support frame on jackstands. Then remove swaybar endlinks, loosen all CA nuts, remove one CA at a time, install frame-end first, align axle bracket hole using bottle jack/ floor jack on the axle. There should be no need to raise/ lower the body of the Jeep when working on the CAs.

Using that method you can replace all four CAs in about an hour or two

Do you guys have a picture of this arm? I just went through an inspection and one of the issues is a rear passenger trailing arm, he also references it as a control arm, so I'm not exactly sure what he is talking about. He also didn't say what is wrong with it. I looked all over and I don't see anything wrong. I was able to find everything else he was talking about, so I don't doubt something is wrong.

I get ya. He wrote up the sway bar links separately. One in the front is actually broken and the two rears are disconnected. Very easy fix. He actually referred to them all as sway bar links, but I think the rear is called stabilizer bar. Either way, I found those and you're correct, very easy fix.
BTW, I had an Atrix 4g and now have an Atrix 2...both seem to be battery hogs, lol.
