Transfer case maintenance.

I am going to attempt to pull the transfer case off the CJ tonight and open it up. This will be my first attempt at doing TC maintenance. It seems reasonable that id brace the tranny with jack stands, then just unbolt the TC from the tranny and mount and side it off.

So now some advice from the experts.
-Am I missing any steps; is there a preferred way to take it off?
-When I have it off and open it up, what am I looking for in order to make sure its in good shape?
-I believe it has a Mile Marker upgrade... Did that effect the TC and how can I tell?
-And of course anything im missing...

Thanks fellas!

With the mention of the Mile Marker kit I think it's safe to assume you have a Quadratrac transfer case.

Here's a good link on what to do for maintenance. Really the only thing to check is the chain tension and fluid condition and you don't need to pull it to check either.

If you decide you want to pull the TC, drain the oil first, and if you have the low range unit, remove it as well. This is probably one of the easiest to pull, of all the TC's put in CJ's

And check out the link CSP posted.

+1 From somebody that has been inside their Q-track quite a few times. While pretty simple, it's not a fun job.

Good call. I'll do a fluid change, and leave everything in tact.

I'll drop the skid plate, it's a mess with various fluids. I worry the TC is leaking, but I'll check it out before giving it a new seal.

I don't remember if the link shows the proper procedure for putting the oil in, there is a correct and incorrect way.
The addition of the low range unit make a difference.

Do you know for a fact the Mile Marker part time kit is present? The addition of lockouts on the front axle is not definitive. If done correctly, the sticker should have been replaced with one that comes with the MM kit.

So I have a few questions about my TC.
1. What is this big "cap" that is on the rear end of my TC? It looks like it would allow for the drive line to go straight back to a rear axle that had a centered pumpkin, but seems unnecessary for my Jeep.
OK, so the link helped with this question. I have QT w/o Low Range. So what does that mean? Why is it called Emergency Drive?
2. How does this thing work? It attaches to a swtich in my glove box, but what is the difference between what this does and manually putting my jeep in 4WD with the lever on the floor?
3. Is this just an electronic sensor that indicates that the Jeep is in 4WD?
Emergency drive indicator switch...
4. I drained the fluid from the TC and I got the fill valve off. Is there anything else I should address while I have the skid plate off and am messing with this area?

Fluid was dark, but little to no shavings on the drain cap.

Thanks guys!
