I gave this a shot, and it worked, for how long I do not know.

Pulled boot down an inch and sprayed Amsoil 5th wheel synthetic gear grease in top of joint using the supplied straw. Noise dissapeared.

Maybe I caused other problems, only time will tell. Ill keep you updated.

Most likely this will help for a short period of time.

when mine started making noise i puilled the boot down and globbed a handfull of all purpose grease all over the ujoint, the noise went away for about 6 months or so

<<globbed a handfull of all purpose grease all over the ujoint>>

Cracks me up. Now that'* my kinda gearhead.

it was an experiment to see what would happen, as i didnt want to do the whole proper process at the time.. and as i said, it lasted for about 6 months or so, but not the noise is back, and i think im just going to live with it.... it doesnt bother me that much

I understand exactly, Oats. I'm going to go the spray silicone route in the next couple of days. If that lasts 6 months I will be very happy.

I've been using that method, on my friend'* 2000 SSEi since replacing my original intermediate shaft and finding that the top U-joint was the problem, not the shaft. I have had 3 in my car. The new shafts last about a year before the clunking starts again. Lubing the U-joint also lasts about a year. Sometimes, you have to try more than one application of your favorite lube before the noise goes away. So, if you try it once, and it still makes noise...try it again.

That is comforting information Archon. You and Oats are consistently fine help. Hope I can help one of you one day.

Will keep all posted as to results.

BTW, do you think I should use a shot or two of WD-40 first to wash some greas away from the u-joint bearings? I don't know if silicone spray will get in there if there is a grease barrier.

You can try that. I didn't have any luck with the silicone sprays. I've had some luck with penetrating oils, like PB Blaster or similar. They didn't last as long, however. What has lasted the longest has been plain old motor oil.
