Differentials Question for XJ
Brand new to this site so bear with me please and thank you. Question is:
If I have an XJ with open differentials and install manual lockers on the front end will I still be able to utilize the open differentials on the front when I put it into 4wd, as long as I don't engage the front's manual lockers?
Or when I install the locking differentials will I be gutting the diff. Housing completely of the open end differential gears/mechanisms?
Thanks again for any help. Obviously have almost no experience with this.

Yes it will operate as the original front did in 4wd without the manual locker engaged. A full case auto locker in the rear would be a great way to go with it also.
If you have or plan on larger tires that would be the time for a gear change also, keep in mind that lockers are based on the gear ratio and a change to like a 33" tire would need a 4.56 gear and the stock 3.55 gears with the locker will not fit the new gear.

Awesome just the info I was looking for. Thank you. You rock. Quick question about your response for when you have time
Curious why you would recommend an auto locker in the rear instead of a manual locker ?

What are your plans for the jeep? Daily driver? Trail rig? A little of both?
Auto lockers are more cost effective and much more manageable in the rear vs the front. Putting an auto locker in the front doesnt give you the option to unlock anytime you are in 4wd, that will effect turning radius and handling.

Selectable lockers are ideal both front and rear, and also more expensive. But if you want to save a little money you could go with an auto locker in the rear like a detroit and they have very good road manners.
Cool man. Thanks. Yea I would prefer to spend a little more to have ideal. I plan on keeping this build hopefully the rest of my life.

If you havent re-geared already and are running bigger tires you should do that when you do the lockers as well. Youre going to have to set up/install the gears onto the lockers anyways. That will keep you from having to pay for the labor twice.
It will make your life easier unless you want to set up the gears twice. If you do it now then youll only have to tear it down once and be done with it.
Take it with a grain of salt but if I had the money I'd go with Ox cable lockers. They keep it simple. Also check the vendor section. I've seen lockers on sale there from time to time.
Cable lockers seem like they would be reliable due to the simplicity. Have you heard much about the reliability of cable lockers? Specifically Ox brand? I have heard back and forths on potential drawbacks and usual hangups for each locker method but not specifically by brand.
