I know this thread is over a year old, but I have an interesting problem. I have a 97 Mountaineer with 5.0 AWD. I was experiencing the knocking noise coming from the transfer case (4404). I first took off and rebuilt the front drive shaft (CV 6 bolt) but still had the knocking. I left the front shaft off and drove it in 2WD for almost 2 years with no problems (other than the parking-emergency brake issues). I finally took the transfer case off to replace the viscous coupling unit. The fluid in the transfer case was a deep blackish color and overfilled, so I assumed the viscous coupling and leaked its fluid. After replacing the VC and seals (kept the same bearings and chain), I took it for a test drive.
Now, I can hear some rattling, scraping noises coming from the transfer case and when I really romp on it, I still get the clunk noise. I think I need to replace the chain as it seemed to have some slack in it when I reinstalled. Wish I would have replaced the first time, but my mistake. The original chain only has one blue link, but everything I have researched is telling me to use the HV-070 with 2 links.
I took the front drive shaft back off expecting to drive it in 2WD again until I can replace the chain. Now, the output to the rear seems to slip. Barely got it back to the driveway. This one has me stumped. Why would the rear be slipping? Maybe the VC I replaced it with is bad, or...?
