CLUNK when approaching ~5mph

Well, i cant seem to find anything about this issue.
Title pretty much says it all. when i get to around 5-10mph when decelerating.
Kind of makes that clunk similar to when i switch to 4 low(now im kind of hoping THATS normal) tranny is only about 3 years old since rebuild.

Whats going on here? any ideas?

To help isolate the clunk, I'd suggest you try shifting to neutral as approaching a few stops to see if the clunk still occurs if in neutral. If so, you get to look elsewhere. If the noise doesn't still happen when in neutral, I'd start by draining the transfer case and refilling with the correct amount of the correct gear oil. Drive the truck and see if the noise is any different. Assuming the noise still happens, I'd then check the condition of the u-joints in the rear and front driveshafts. If the noise has not changed, or is still pretty noticeable, you'll probably need to have someone take a look at the transmission. Do you know if the bores were drilled and sleeved at the time of the last rebuild?

If it is still on rebuilder's warranty, TAKE IT BACK....... Check the bell housing bolts and the transmission cross member mount.... Philip

Don't know if this will help or not, but I had a 'clunk' in my '91 EX for approx. 8 years that I tried to localize in my suspension system. The shops I took it to cited everything from the wheel bearings to the steering column bushing.

About 3 months ago, I took the shroud off of my steering column to try to localize the 'clunk' myself, and found that the heavy horn plate had 2 rubber standoffs that were actually broken, causing it to 'clunk' in the steering wheel with every turn and bump. A little super glue and she's been perfect and silent (just like a woman should be). LOL!

Don't know if the 2nd gen Explorers changed the horn setup, but if not, this could still be suspect for yours.

Noticed this post in the last thread, on a different issue. This thread is questioning my transmission noise rather than suspension. thanks for your help!

Not trying to be annoying. I didn't pick up that you were speaking xmission. Sorry. Since I was suckered into just about every part on my EX trying to localize my own clunk, I'd hate for anyone to suffer for as long as I did.

Best of luck.
