welded differential

I have a 95 YJ with welded differentials (lockers). It is my daily driver and I am wanting to do something different before any damage is done. Can I simply buy and install another locker such as a Detroit or am I looking at an entire axle replacement?

edit:
Or really I wouldn't mind simply going back to stock if that is possible.

If just the spider gears are welded, there are a couple different ways you can go about it.

The easiest, and most likely the most expensive route would be to replace the carrier with a full case locker such as an ARB, OX, ECTED, or Detroit.

Another option would be to spend the time to grind/cut out the welded spider gears and replace them with new gears. This will set you back to stock form. This would probably be the cheapest route, but it would also take quite a bit of time probably.

You can also do what is in the last option, by cutting out the old spider gears. Instead of replacing the gears with new gears you can look into a lunchbox locker. This locker will fit in your carrier rather than replacing the carrier.

In the end it all comes down to how much time and money you have.

No. That is a limited slip and it's a full case. Look up the lockers such as an Aussie locker. They are lunchbox lockers

I believe so. It is hard to say, since I am not positive how its welded inside...but if it is done how I think most people do it, the aussie locker (or something similar) should do the trick.

That is also another option. I would caution locking the dana 35 (although you appear to be locked now as it is). Depending on what tire size and gear ratio you are looking at now (or in the near future), a locked dana 35 can be a ticking time bomb.

I too am looking at locking my jeep up. I have a standard open case now and looking at going with the aussie style lockers rear and eventually front too I have 31's on it with the 4L straight six in my yj. I am aware that the dana35 axles leave a a lot to be desired in durability but I am looking at making this jeep a bit more capable during my light off roading adventures. I don't tend to beat on my equiment but a few times the locking diff would have been nice and gotten me out of a few jams. Thoughts and opinons are welcome.

I am running 35s on a stock dana 35. Its just a toy an I have some dana 44s so i though i would weld the rear just to break it! It still hasnt broke anything yet! Im not too hardcore by anymeans but its been in some pretty nasty mud holes and up some pretty tight hills about every weekend. The dana 35 is stronger than it gets credit for in my opinion.

X2. The Dana 30/35 combination takes a larger beating in these forums, than in any off-road use. 5+ years I've been running the 30/35 w/4.56s and ARBs on 34" tires and have only broken one axle U-joint. In all fairness to the U-joint, it was 14+ years old, 11 years off-road only.

Lockers are a good investment, especially the switchable one like ARB, Ox and Eaton Elocker. Mine have saved more broken parts than they've caused. When you need them, they're there. When you don't, they're not.
