No matter what I do I can’t get the ring gear side to seat and get the bearing cap to go on….been at it for three hours now….just put one in the front a few weeks ago no problem

You either need to buy 4.56 gears OR buy the numerically lower ratio e-locker.

I have 4.56 gears why would I go lower?

What @Lou said. You need EATON Part #: 19977-010 to use with your thick style gears or you need to buy new gears

If I need new gears would I just need the ring gear and not. The pinion?

The gears you currently have are the thick style, which were used in the rubicon axles or when using a numerically lower carrier.
Gears are matched sets; you can't change just a ring gear.

So I need a different locker like @williambmac said

Yes.

Think about this...the numerically higher the ratio, the smaller the pinion. The ring gear needs to be set in the right location to mesh with the pinion. Shims and spacers only get you so far so there is something called a "carrier break" where one version places the ring gear closer to the pinion for 3.92 and up, and farther from the pinion for 3.73 and down.

Sometimes you gear from 3.73 to 4.56 and don't want to replace a perfectly good carrier, so along comes thick cut gears which lets you put 4.56 on a 3.73 carrier. I believe Jeep also did this with the Rubicon, though I'm not entirely sure why because it was a unique carrier anyway.

Your gear setter got thick cut gears 4 years ago so you wouldn't have to buy a carrier. Now you need a 3.73 and down carrier to work with those gears.

This is what 4.56 standard (not thick) gears looks like on a 3.92+ elocker.

Exactly what mine looked like
 
And just another note...the reason you didn't run into this on the front axle is because the Dana 30 breaks between 3.73 and 3.55 (instead of 3.73nand 3.92 like the 44), so all TJs (except some oddball 97s) have the right carrier to regear without crossing the break.

The ring gear looks crooked to me is what I meant
