my poor old heep is a 1984 cj7 4.2/ t5 /dana 300/ amc20
well i was changing the rear diff lube to day and found out that i don`t have a locker like i was told when i got the jeep. but really a lsd so badly broken that it works like a locker. my ???? is what type is it. can i buy parts to fix it and were to get them. and how hard this will be to do.
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.
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.
