Fixing output shaft damper weight

Hey guys.
I was driving home, and was about a minute away, when I get this massive vibration through the entire jeep and the drivetrain. I was doing about 30mph, so I pull over on a side street, and take a peek undernieth, but I can't see anything wrong, so I decide to drive the rest of the way home slowly.

On the way, I hear what sounds like glass bottles clanking around undernieth.
So I get home and put the jeep up on jackstands, and put it in gear. Right away I see the problem on the rotating driveshaft.



This "ring" was down by the D35 yoke.




What is this thing? How did it get dislodged and how do I fix it?

I'm assuming that it was from here, but it looks like it needs some sort of spacer between itself and the T-case output to fit.



Edit: Sorry for the massive pics, I just resized them.

That's the output shaft damper weight. That's supposed to be on the t-case on the output shaft.. It's just pressed on, and you should be able to just hammer it back on. You need to be careful to make sure you're putting it back on straight though.

edit: I can't really tell you why it would come loose.. never seen that!

Hammer it back onto where? It just sits loosely on the silver ring of the T-case output shaft right now.

Thats your harmonic balancer for your NP231 (not all of them have it). They come loose rather often and are a source of a lot of "wierd" noises. I have seen it happen on a couple Jeeps. You should be able to press it back on. Looks like you lost the rubber gasket that holds it together between the metal surfaces though. (without the rubber gasket you will not be able to "hammer it back" in since that piece holds it together) You should be able to run with out the larger ring, I would just drop the shaft and take it off. When you put an SYE kit on you have to remove the balancer all together. If your looking at doing a lift down the road and have some money to spend you could just do an SYE kit now.


EDIT
I might have my old one you can have if you want to pay for shipping. I can check tommorrow, i'm at work today.

FYI my FSM says only the 4.0+NV3550+NP231 combo has the balancer.

Does anyone have a P/N for that rubber gasket? If not, i'll take you up on your offer Benderff if you still have yours.

But I can't be the only one that noticed the missing piece of universal joint guys. Look closely at that pic. It really looks like one piece of the u-joint is gone.

The Jeep is my DD, so i'm going to try and get a P/N from the stealership for the gasket.

If you guys have a P/N, feel free to chime in.

Also i'm assuming I have to take off the rear driveshaft to get the gasket on. What's the easiest way to get the driveshaft off? I've never taken a driveshaft off before, so step-by-step instructions would be great!

I'm pretty sure I have it still! I have the NSG360 and my NP231 had the balancer. The drive shaft is easy. Just unbolt the caps on the other end of the shaft by your axle. You should drain the fluid in your transfer case since you will have to pull the other end out from the case.

Can I jack up the rear end real high to avoid draining the fluid? I just put in RP synthetic, and I had to order it from the states at a high border cost.

Shaft looks fine to me, I think it's just the angle.

No need to drain the t/c as the output shaft has the seal. The d/s slips onto the output shaft. I drove around for two weeks without the rear d/s installed... no leaking.

Yeah i was looking at some pictures, and that's what I gathered too.
So once you take off the driveshaft at the rear diff, it just slides off the output shaft splines and you can drive around in 4wd with no problems?

Looked to me like the joint might be missing but it must just be the angle of the pic.
