Ok, this is my situation for which I am asking TRUE jeep wrangler experts for help. I want to replace the entire front axle to a (MOPAR Dana 44 complete front axle assembly that comes with 4:10 elocker) I can do this on a weekend, with no problem. My rear is oem with open diff and 3.21 gears. I'll have to take to local installer to have this done since I don't have the tools or location to do this properly. It would be my first time replacing diff so it would take me longer than the experts. I also can't have my car off the road since it's my daily driver. The DANA 44 front axle should be fine for mudding. I don't do rock crawling so gearing should be a nice compromise. I hate 3.21 gears

My question is can I install front axle with 4.10 and have rear be oem with 3.21 for a short period of time without creating an issue? If I'm not mistaken, as long as I don't engage the front axle I should be fine. Am I wrong?

Just don’t put it in 4wd and you will be fine. I drove mine with 5:13s in back and 4:10s in front for about a year before I had time to regear the front. No problems.

This. Did the same when I swapped a front axle in, had different gears for two weeks.

As stated, no problem doing this.

If you want more peace of mind, leave the front driveshaft out until the rear is done

What size tires are you going to be running? If you're on 35's or bigger (or even in the future), you should think about steeper gears than 4.10. I went from 4.10 to 4.88. Wish I had 5.13's.
