Removing Rear Locker

I have an 04 TJ with a Dana 44 in the rear. The PO used the vehicle for more rock crawling than I and put Spartan Luchbox Locker in the rear. I use the jeep for more a daily driver and do not like the road manners of the locker. I also have a Aussie locker in the front which I intended on keeping in place. With the 4.56 gears I want to remove the locker in the rear and put in new spider gears to improve the on road driving. For a person of moderate mechanical skill, how difficult is it to do this and where is the best place to grab a new set of spider gears? Any and all help is appreciated. Thanks.

You will also need to purchase a new carrier. Have you considered installing a limited slip such as a true trac? I am going to remove the detroit true trac from my D44 and replace with a Detroit locker. Wish there was some way for us to swap.

My mechanical experience includes installing a new engine in my chevelle and I would never even consider screwing around with installing or removing. full case locker.

Big Cole, Thanks for the input. Was just doing some other research on regearing and am seeing the same thing, is a big job to tackle on you own. May have to call the local shop and see what they charge to do it. Here we go again$$$

Also, am not opposed to swapping just not sure how we could do that at the same time, Jeep would be down for too long and it is my DD. How many miles on your locker?

No clue on the mileage. It was installed by the PO. Swapping would be a total hassle for all parties and probably too much effort. Good luck. I'll definitely post the true trac in the classifieds when it is available.

There should be no need for a new rear carrier since the lunchbox locker was simply inserted inside it after the OE spider & side gears were removed. Remove the lunchbox locker & insert new spider & side gears into the existing carrier. No setup is needed for those particular gears.

If you keep the OE carrier & simply put the shims back where they came from, keep track of which shim came out of which side, you will not have to set the back lash again.

You can often find used good condition side & spider gears with their required cross pin in a 4x4 shop that installs lunchbox lockers.

My bad. For some reason my brain thought the OP said Detroit not Spartan. Sorry for the bad info.
