Front Axles - 4wd WJ

I replaced the ball joints on my 2003 WJ this weekend. Took the axles out and then put them back in to discover that each side rotates opposite of the other. I can tell this because I rotated the brake rotor on one side and could see it turning the opposite on the other. Is this something that will correct itself when I start driving or go in reverse? I appreciate any insight as this is my first time doing this job.

This is normal operation for a standard differential (due to the spider gears performing their differential action)

If you had a L/S or a locker they would both rotate in the same direction.

Thanks CJREX. So, I'm good to go when I put the beast down off the jack stands and back out of the garage? At least in regards to this opposite rotation?

As CJREX said, that is normal. Because the tires are not touching the ground, the axle acts like that. On the ground it will function correctly.

you can get someone to hold the other wheel still, and then rotate your side. it's normal for the open diff to do this. the false sense of security guys get seeing "4X4" on the back of their jeeps, gets a lot of guys stuck. you need sure-grip (posi) or a locker, to get actual 4x4, and you'll need it on both front and rear. if yours didnt come equipped with lockers.

There are some good explanations of how differentials operate here:
