1979 Cj-5 silver anniversary
 
Hey guys, my uncle has a 79 cj5 silver anniversary and its pretty sweet. Its in terrible shape though and it just sits outside and is rotting away, so i want to buy it off him and save it. Its a 304 with a 3speed and i know it has power steering might even have power brakes. It runs really good. My cousin plows my great grandmom's drive way with it. I wanted to know if the rears were locked in them stock. I think the front has locking hubs, but i really want to know if the rear is locked. If anyone can help that would be great. Thanks

The front will have an open differential (no locker) Dana 30. (Note that locking hubs simply disengage the wheels from the axle allowing the wheels to freewheel, saving fuel and wear)

The rear should be an open differential AMC 20, no locker.

A "lunchbox" locker can be added to either differential with a few hours work.

So what exactly is a "lunchbox" locker? And are the stock axles pretty strong? Im not going to use it for any crazy use so i dont need insane axles.

Lunchbox locker: Common term for an automatic locker that can be installed without re-setting the ring & pinion. It is inserted into the existing case (carrier).
Look up LockRight, Spartan, Aussie.
Can be added to front or rear axle.
A front locker will cause some steering issues (understeer, difficulty in turning) when in 4WD.

The rear axle has known weaknesses. You can make it somewhat respectable with some upgrades.
Suggest you replace the axle shafts with a good set of alloy 1-piece axles (check Superior brand).
The tubes are thinner than a D44 and have been known to spin in the housing... some extra weld to attach the tubes to the diff center section are a good idea if you plan on moderate or harder wheelin.
For harder wheelin, some guys add a truss to prevent bending tubes.

Lots of reading out there if you use the search.

Awesome. I greatly appreciate it. Lots of money are going to be going into this. Fiberglass tubs are not cheap

My uncles runs flawlessly and hasnt been moved in a couple years. I start it up every now and then and it fires right up every time. I dont know how old the gas and oil is. The only thing holding the body to the frame is brake lines and wires. Everything is rusted away. Its a shame. Thats why i want to save it. It could easily be saved and im looking for a nice easy project. If i can get it for 300 i think i will be off to a good start.

is the frame good?

if you aren't planning on plowing, you might be able to take that off and sell it and use that for a new tub/front clip, etc.,

keep us posted. i'm going to start taking photos/doing a write up of what i'm tinkering with.

good luck
