U JOINT ISSUE OR TRANSMISSION on 2004 Ford F-150

Most of the time when I take off from a dead stop, there is a clunk noise from under the truck. Last year I had 1 u-joint replaced and it seemed to work fine, but now the sound is back. Is it possible that another u-joint has gone bad? I know the repair shop had a hard time finding a ujoint for the 2004 f150 supercrew and had to get some work done at another shop and it was quite pricey at around $300.

This vehicle could have an issue at the extension housing of the transmission. The oil supply hole to lubricate the extension housing sometimes gets clogged, and then things get worn and loose back there. If this is bad, I can see where a U Joint could be condemned instead. Have this looked at first thing.
