Nothing special. Just RTV. Gear oil isn't anything special and commonly available at all parts stores. Your diff cover should have a fill plug right on it (bottle will have a nozzle). You just put the cover back on, let the RTV set up, and then add oil until it comes back out the hole. What oil you choose will depend on what you find in there.

Wow that sucks. I guess I'll pull the cover off and see what they did to the inside of it.
So that means basically if the front is spooled or welded that I no loger have 4x4 unless I want to be locked and have scary driving. Fuck that sucks.
When I put it into 4x4 without using the cable it sure feels like it's in 4x4 like the xj did. Is that just because the transfor case is engaged?
I still like the jeep.

Ok I'm going to attempt this after work, sounds easy enough. Thanks.

The fact that you have a disconnect device has no bearing on whether you have a locker. We're just telling you that cable is it not a selectable locker. An automatic locker would cause the same "scary" on-road driving that a spool or a welded diff would.

What exactly did the PO tell you the vehicle had?

chance that the front axle is open, aka STOCK. I would say yes open and inspect the front axle, clean it out with brake cleaner, scrape off the gasket on the housing and cover, run a bead of black RTV along housing gasket surface, bolt on cover again and finally refill diff full of fluid, 80-90w. Fill the housing till fluid starts comming back out the fill plug.

I may have totally misunderstood what the guy told me. I believe he said it had a detroit in back but doesn't know what exactly is in the front. He explained it to me like this:
The front has a locker in it when you put the jeep into 4 wheel drive it drives like a normal 4 wheel drive because the locker is in there. When you pull the cable it slides a sleve that locks both axle shafts togeather which then makes both front tires turn at the same time. He said if it didn't have the locker up front I would need to engage both the transfer case and the cable to have normal 4x4. With having the locker up front when I engage the transfercase it works like normal 4x4 with power to one wheel up front.

I misunderstood it when he explained it to me the first time and thats where I came up with the selectable locker thing. Sorry that was my fault.

If it has a locker or spool in the front differential, that is true the way he said it.

You still might get some handling quirks since only the driver side wheel will be powering the front end 100% of the time (by not engaging the front axle with the posi-lok), as opposed to an open differential that can differentiate power output between both wheels.

I'm going to open it just to see whats inside it, but I believe the po because it acts just like he says it does. When I put it in 4x4 it feels like 4x4 when I pull the cable it doesn't turn for shit.

If I was to put it on a lift and engage the transfercase case it should make one wheel up front turn and one in back right? If I pull the cable then both wheels up front would turn right? I might try this on my way to work if it would help me determine what I have.

You may have misunderstood, but what he explained to you is not exactly correct. It does not drive like it is a "normal 4wd" when you engage the transfer case, because the passenger wheel won't get any power at all until the Posi-lok is actuated. "Normal 4wd" with an open diff will send power to the wheel with the least traction, but that isn't always the same wheel. It will also send it to both whels when traction is balanced.

No. If it is set up the way he described it, both rear wheels will always turn and the driver's front wheel should always turn when you engage the transfer case. When you engage the Posi-lok, the passenger front wheel will start turning as well.

If the front is open and you're in 4wd at the TC, the driver's front wheel will probably start turning, but you should be able to stop it. If the Posi-lok is engaged with an open front diff, the passenger front wheel will start turning when you stop the driver's front wheel. If it isn't engaged, nothing in the front will turn when you stop the driver's front wheel.

(I think. )


Edit: This is assuming the vehicle is off the ground.

That rocks, I'm sure it has a locker in it just by the difference I feel when I pull the cable. I am going to look though becauseI want to know what exactly it is and what it looks like, and thats the only way I'll learn.

Yes, except both backs should spin (you said it has a Detroit in it)

well is it safe to drive it in 4x4 on the roads like that without the posi-lok?

Ok. I'm sure the rear is locked. When I give it any gas around corners it slides like crazy on the slipery roads. However in the xj with the welded rear end when I turned it would feel kinda like it was binding up and the when I would turn sharp it would chirp alot! The jeep I have now doesn't bind up or chirp like that unless I hit the gas. Maybe it's not working right? Should it do like the xj did?

It's snowing in Coldwater right? Seems to me you coud find out if the 4WD work and if your locked or not pretty easy. Get into some snow, engage the T-case (not the cable yet) and give it some gas. Do either of the front wheels spin? Grab a buddy to watch the pass side while you watch the drivers side.

If nothing in front spins, your open. Now engage the cabe AND the tcase. What happens? One wheel in front, both wheels?

That is working right, they lock under power.

Man we got maybe a inch of snow but I know where a nice patch of ice is at work so I'll try it. I might have some help close by!
