Engine/Transmission (1998.5 - 2002) Bad NV241HD? or ???????

I have a really bad vibration in my truck that starts up if I am running down a bumpy road. I thought it might be the right front hub but it wasn't. I changed it out today and I still have the problem. Somebody mentioned that it could be my front axle disconnect so I checked that out and it is working fine also. The truck will not vibrate in 4wd only 2wd. When I get the vibration, it will go away if I move the transfer case shifter slightly towards 4wd or neutral. I thought this was coming from the front of the truck but now I am not sure. I heard about a problem with a snap ring on these trucks coming loose in the transfer case. Would the symptoms I am having be caused by this? I am planning on a camping trip next weekend pulling my fifth wheel so I am getting desperate to fix it. Any ideas? Thanks

I had a simular thread going in the non engine section and posted the resolution there. I'll put it here as well in case anyone is interested.



Vibration fixed. I figured I would post this so that anyone else that has this problem can diagnose it by searching the forum. The problem was resolved by adding oil to the CAD. When I first opened it only a small amount ran out into the drip pan. When I found the play in the end of the outer shaft, (it turned out to be about 1/8" not the 1/4" that I thought before) I knew that I had found the source of my problem. I added the 5oz of gear lube to the CAD and now the vibration is completely gone and as a bonus, the outer seal still seems to be holding. The oil must help damp out vibrations between the two shafts as they run together in the plastic bushing. I cannot get over the fact that there does not seem to be any bearing on the shaft near the cad only the plastic nub. I saw on quad4x4 website that they sell a needle bearing, bushing and seals for the outer shaft but I could not figure out where in the axle the bearing gets installed. It is not shown on the exploded view at the dana website. Main thing is it's working now with no leaks and no bad vibes.
