Here's another newbie question.

What is this and why is it leaking transmission fluid? It's a very very slow leak and the level still looks fine on the dipstick but... I don't like things to leak at all if I can help it.



Up close it looks like the gasket is broken.



Thanks

You mean you can actually get somebody from the parts store to actually go outside and look at your Jeep? Wow.

I guess customer service still exists in some places. That's good to hear. I could try that, but based on past experiences I think it's doubtful they'd have any idea what it is either.

But, don't worry, I'll get them started on the right track in their computer by it's location I think. Hopefully they won't try and sell me the whole master cylinder to fix it.

Maybe a little dab of silicone would do it for now.

The parts catalog labels that as just a "grommet" for the brake booster check valve, so I don't think it's important if it's cracked or not. If you feel the need to buy a new one you probably could from a dealer or from factorycryslerparts.com. Part # is J3208510.

Actually, after 96 i believe, they output shaft on the tcase has a fixed yoke that is bolted to the output shaft. Before that , they came with a car type tail shaft that had a sliding type slip yoke that if it came out would dump the fluid. The newer design since it is fixed and the drive shaft slips inside itself can be removed without losing the fluid and driven by the front axle alone. The newer drive shaft has a splined slip design like the front drive shaft. But it is not a slip yoke. A slip yoke means the yoke where the Ujoint bolts to slips in and out of the transmission or Tcase tail shaft and has a seal around it.
The extra length of the newer non slip yoke Tcase means the drive shaft has to be shorter which in turn means more of an angle on the Ujoints when lifted than the older style slip yoke design that have a longer drive shaft.

Here is the older type Tcase that you and I have:



Here is the newer design that the 96 and newer XJ's have. I am not for sure on the year they started but I think it is 96.
You can see how much longer the tail shaft is and how much shorter the drive shaft would be:



As far as the pinion angle all XJ's have about the same pinion angle from the factory regardless if it is a 8.25, Dana 44 or Dana 35 through all the years. If there is any difference it is very small.

That's your transfer case for your 4-wheel drive. Looks like it's leaving between the case halves. You can't check the level from the tranny dipstick though...there are two big hex plugs on the back of the case (visible in your picture). Take the TOP one out and stick your finger inside to check the fluid level - should be at or slightly below the bottom of the top fill hole.

That's the transfer case the way you check the fluid level is to unscrew a plug on the back of it. It will tell you how in the factory owners manual. It takes automatic transmission fluid.

Oops I guess you were a little quicker dukie. You always answer questions better than just about anyone anyway.

I can not believe you are arguing with me about this, you are completely wrong ask anyone on this forum all xjs have a slip yoke, the need for a slip yoke eliminator is actually more prevalent on post 96 xjs. Having a non slip yoke output actually gives you a longer drive shaft. That is the whole point of an sye. Don't answer questions if you have no idea what you are talking about. Here is a pic of a post 96 slip yoke.

Correct... Im with you, the FRONT is obviously a fixed yoke, but the back of the TC is an external slip yoke

you guys need to read this:

The only difference between the earlier and later tcases is the presence of an internal oil seal around the output shaft between the main housing and the output housing. Early ones have the slip yoke lubed by the Tcase fluid, later ones are sealed and greased (thus the rubber boot).

Modrod

Okay, maybe you can call that a slip yoke, but in the classic since it is bolted to the output shaft and barely moves I have never considered it a "slip yoke". And as far as knowing what I am talking about I have been a mechanic for 35 years, I have been a Ford, Nissan and Porsche mechanic. So I may not know everything like maybe you think you do, but I do have a ton of experience and knowledge. But I don't know everything. We learn all our lives and if anyone thinks they know everything, they know nothing.

assetts91

It's still a slip yoke tho.... Fixed yoke would mean the actual yoke itself would need to be unbolted to take it off.

bhennessee1

Jeep never made an xj with a fixed yoke. The post 96 transfer cases still have a slip yoke on the rear read the link that dukie posted. You are truly unbelievably misinformed.

bhennessee1

Sye means slip yoke eliminator. So why the **** would you use a sye if you already have a fixed yoke? Holy ****.
And yea I have seen the post 96 t case since it is in my jeep and I have taken out my drive shaft to change the u joints. My xj is a 2000 I don't know where you got that is had a pre 97.

Modrod

I looked at my newer Tcase and you are right about it. I thought I had seen these with a nut on the end of the yoke where it was attached to the output shaft.I know the SYE's have that.
When I have been to the Upull it place and read articles I thought I had seen it was bolted to the output shaft.
So, if it is not clipped or bolted to the output shaft, when you take the dshaft off how does it stay on if you drive it with the front axle? It seems it could work it's way off and fly off without anything retaining it.

bhennessee1

Im done with this argument, but i want to tell you since you said we all need to learn, which i totaly agree with that the yoke is not bolted to the output shaft at all, it slips rite off. just like the old ones. I dont think i know everythink, but in the case i know exactly what im talking about and clearly you dont. The fact that you have 35 years of experience as a mechanic doesnt mean that you know more than me or the other people who were trying to inform you that the newer transfer cases do indeed have a slipyoke about this particular subject.
