Hi all, I own a 1997 Ford Explorer w/ AWD and 5.0. I have had it for about 8 months now, and it currently has a little over 170k on it.
I have recently experienced thumping/clunking noises in the drive train that starts out slow, and gets louder and faster with engine speed, and upon turning. I had originally thought it was comming from the front drivers side, which led me to believe it was a axle shaft/cv joint. I replaced the axle, and the noise still continues.
I finally decided to get it up all all four wheels and do a check with it in drive. It now appears the noise is coming from the driveshaft that connects the front diffy to the transfer case. The driveshaft seems to vibrate, and cause the noise. Also, with it in neutral, as I rotate the driveshaft by hand, I am hearing a tapping/clunking noise in the back of the transfer case. It doesnt seem like the Differential to driveshaft U joint is bad, as it has no play in it. So the only thing I can think is the transfer case.
BTW, I checked the oil level in the transfer case, and it is good. I figure it is about time the transfer case went bad anyway, since it does have over 170k on the clock.
Anyone with experience with these transfer cases, and think this is the cause of the noise? Please get back to me! Thank You!
