This is a big clue! Most likely suspension related, shocks, springs or sway bars. There isn't much else back there.

Well I hope you report back. I have the same exact problem with my 99. Just checked the tranny fluid and it seems good, not burned and full. I'm waiting for something to grenade at take off soon! LMAO!!!

tracked it down to the slip yoke. found it was covered under warranty (extended). Ford replaced the hole drive shaft. So far the issue hasnt returned.

If your Ranger is not under warranty, evidently lubing the slip yoke is not a big job. I plan to give it a try. Here is a web site with photos on how to do it. http://www.explorerforum.com/forums/...d.php?t=106307
I assume that, since Rangers and Explorers have the same drive train, the fix should be the same.

Just a bump for this thread. I'm interested to see if anyone else came up the same answer or a different solution.

I figured the problem out. Not leaf springs, not rearend, transmission or transfer case. Ford released a training bulletin I found. The slip yoke on the front of the rear drive shaft was improperly greased during assembly. I removed the driveshaft (about 10 minutes) and put it on a work bench. Slid the slip yoke out and Cleaned it real good with WD 40 and a rag. Bought a can of Motorcraft heavy duty grease ($4 at autozone) and packed the slip yoke with grease. Worked perfectly. No clunk, no shudder, no slipping what so ever. Easy fix. I believe it was Ford TSB 427 that explained the process completely. I Googled it and printed it off and followed the directions exactly. Total time was about 1/2 hour.
