Looks like a richmond power trax lock-right. I just installed one in my front D30 last weekend.

The pins and springs are to keep the locker "locked" while moving straight and to allow it to "slip" when turning.

Lock-right i have one in my front d30 on my 7. Yours looks kinda funny though, not sure why it's notched around the spring/pin, mine wasn't like that.

Well these are excellent lockers and should out last your axles... so sounds like someone prior to you did not install it correctly

You can call richmond and send them a couple pics also with your axle specs and they might be able to send you out some replacement parts.

easiest way to know is pull it out,
to do this take out the center pin, in the pic i posted (not mine btw) up by his middle finger you can see a large circular opening that's where the center pin is, get that out,

its held in at one end by a pin, which needs will probably require a punch and hammer.

then after that you pull the springs out, use a small screw driver or a dental pick,

then slide the pins where the springs were

then take out one of the 2 center pieces, then the other

It might be easier to just pull the entire carrier out and work at your work bench vs on the ground in your garage. You will need to slide out your axle shafts, remove the bearing caps, and gently pry the carrier right out.

Since it looks like you have a smaller ring gear, you should be able to slide the pin out w/ out removing the ring gear from the carrier. Make sure you have the correct size punch to get the crush sleave out from the pin... it can be a pain. Once the center pin is out you can start disassembling the locker by following the steps JeepnBlake mentioned above (remove the springs and slide the pins through the other side). Make sure you don't lose the spacer washers once you remove the carrier.

Hopefully everything comes out smoothly and some replacement pins and springs is all you need. Let us know if you have any troubles.

Here's a write up for the lock-right install which might come in handy for you.

That's an AMC 20 'Open' differental carrier,

That someone has put a 'Lunch Box' locker into.

I'm with the other guys, I don't know why the pin holes split out like they did unless there was too much gap between the halves, but that is a WILD SPECULATION, since I'm not real familiar with diagnosing problems with 'Lunch Box' lockers...

$200 to $250 solves the problem by getting a new locker and throwing it in there,
Not much to them, really easy to install with a feeler gauge pack and basic hand tools.
