So I'm wanting to put in some lockers on my Jeep wrangler 03 tj. ( sport) It has a dana 30 front and 44 rear, axles are geared to 4.88 and running 35's with 12.50 rims. I use my vehicle as a DD but go down to Moab for a lot of events. My main concern is I don't want to put work into my front axle cause I heard a dana 30 with 35's and being geared wont hold up a locker, but at the same time I've heard the only difference between the Dana 30 and 44 is just the axle shaft. the U joints and everything are the same? But I haven't looked into it much, so some people say a dana 30 deserves more credit and can hold 35's and a locker. So for now I want to just put one in the rear. I'm looking at doing a Detroit locker,or an Aussie, but that's gonna be engaged the whole time?. Also another thing, what would be a better option, lockers or a transfer case gear, do a 4-1 crawl case. I've seen people in my group go up things just fine cause they have a transfer case gear and no lockers. So I guess two questions here, lockers for the rear for a DD. Or just do a transfer case gear 4-1? Thanks for the help! I do live in Utah so we get a lot of snow, so having a locker in the rear would be a little hard to drive with, could use the help.
