Thanks to all who contributed to this tread. I just greased the u-joints and propeller shaft (3 points) 1st time. It was easy to find if you follow this tread. Now my stop and go clunk is gone.
Make sure you buy the flexable hose if your grease gun does not come with one. The middle nibble is almost impossible to get to without it. Also it's less dangeous to do this job when the car is cool down.
Have fun.
