2004 Supercrew rear end help

I have a 2004 supercrew with the 5.4 and 3.73LS, when I take off from a dead stop it makes a clunk sound. It is not all the time and is not real loud. It just doeswhen you take off, and if I baby it off the line, it is not as noticable. I took it to my local ford dealer and they said nothing is wrong. I know it is not normal, so does anyone have any idea?
Thanks for the help
Kurt

There is a tsb on this I had it also they should know about at the dealer... what needs to be done is to grease the rear spline/yoke on the driveshaft..after it is greased it will be like new!

I had a service tech ride with me, he said it is not the drive shaft. But he also said it is a normal noise. He said that it is due to the Limited slip. So I asked him that if every Ford that comes with a LS makes this noise. He really did not have an answer. So I am going to another dealer so see what they say.

I can see it making some noise around corners and such, but it shouldn't be doing it all the time, especially on the straights...just my .02

Tell them to grease it anyway it only takes a short time to do it and they can do it while you wait..my dealer did it and I still have the paperwork it is a TSB they drop the drive shaft clean the splines and lube it up and it stops it... it is not a normal noise! if it was not there before than it is not normal
