Clunking sound when I shift from P to D

[Tiwaz]

Just like you can hear between 0:29 and 0:31 the transmission makes a clunking sound but it only happens in the morning with cold engine. It sounds like someone taps a steel part with a hammer.

Any clues...?

Do the same thing but from the front ujoint and transfer case.

That U joint is bad at the transfer case, you can clearly see the play in it (at the 2 second time mark), also any time you see red (rust) around a U joint it is likely bad.

Yep it's a bad U Joint . Should be an easy fix but change them both out F/R While your in there.

can anyone suggest a part number or a vendor?
(are both joints the same part number?)
I am not very mechanically inclined and afraid of buying the wrong parts.

Bad u joint, and possibly lose differential. My differential (215000 miles) is somewhat lose, and makes a klunk way louder than that. No major problem so far. Someday I will replace it and rebuild the old one. Use the TM to get the correct part number for the u-joint.
