Strange clunking on deceleration
Hi all,
I have a 1999 ranger 4x4 with a 3.0. automatic, extra cab.
I have noticed that sometimes (this has happened twice so far) on slowing down, (just letting off the gas) it will make a large clunking popping noise like you hit a large pothole and bottomed the truck out (or if you had hit a small animal) However, both times nothing was in the road way and no damage was done to the truck. both times it has been in 2high.
The truck does not swerve, grab or anything funky other than make a loud CLUNK every now and then.
This has happened when you let off the gas at about 25mph and coast along. (it may be when you apply gentle throttle to keep rolling, but I can't remember, I was not driving the truck this time, the first time it happened was several weeks ago and I put it off as a freak happening).
I will check the usual suspects, u joints, ect, but I was wondering if there could be something else happening...
perhaps something in the front diff? or transfer case? It kinda felt like it came from the front of the truck.
thanks for any help!

A good cleaning, white lithium grease, and used zip ties(2 per end) to replace the metal bands that have to be cut off the boot. Its been around 6 years now since I did mine and have never had a problem again.
