I have a leaky c6/married leaky np208 in my 84 and just today have noticed a rattling coming from my transfer case (or that general area) and can feel a vibration that matches the rattle through the transfer case selector.

This is happening in 2H and increases if I accelerate heavily (I just had to do it to see if it would go bang or not). Also when in reverse I am hearing a repetitive clicking noise coming from the same location.
I have locked the hubs in and tried 4 hi and low but at lower speed and rpm and no noticable rattle over the cabin noise, but as I said I didn't get up to highway speeds or put the boot into it.

here are a quick list of the symptoms:

-rattle under load in 2wd
-clicking from transfer case or gearbox when reversing
-slight clinking from input/rear output side of transfer case if i rock the front drive shaft with case in 2wd and fron hubs unlocked so shaft is unloaded (not sure if this is normal play or not).

So I guess my questions are:
- does this sound like the chain has loosened up or would there be another reason for the noise?
- how worried should I be?
- if so am I able to remove a link to adjust or do i need to replace it completely (It will be had for me to get here and if i can adjust it i would
prefer to for convenience).


Any help would be appreciated.

I have the NP208 in my 85. I am having a bunch of issues with it too. Damn oil seals keep poppin out and leakin fluid. I also have a cracked flexplate. That shit makes a ton of noise when I start under minimal load. Anyways, I'm not exactly sure about what is causing your noise, but I am sure that you can't just remove a link from the chain.

Driveline U-Joints? Alot of people describe the same symptoms with faulty U-Joints.

Mr Gaddy, I actually came across your thread when I was searching this problem and I can see what you are saying about removing a link it would be like an exercise in knitting trying put the thing back together even if you could get removable links.
Randyb12 thanks for the tip on the u joints, ill look into that right away.
