mystery clunk in front end

[dannymurphy]

my 2000 windstar has a clunk in the front end. the strange thing is that it is intermitent and it seems to come from different spots in the front
sometimes when i come to a bunch of small dips it sounds like its coming from the passenger or driver struts ,
i recentally had almost everything replaced in the front of my wind bag i have new:control arms on both sides; new ball jhoints ;new sway bar link on pass side ;new sway bar bushings ans new wheel bearings. all of this was done at once. so it seems that all i have left are the tie-rods and the struts. now the strange part sometimes when i go around a turn the friggin thing clunks when i straighten the wheel
the clunk seems to come from the steering gear as i can feel the clunk right by my right foot when driving. after i had all that work done it was good but a couple days after i had this mystery clunk
i have had it to 2 differens shops and one said there is nothing that he could find wrong <he did'nt even charge me!??> the other one that i usually go to figured that it was the transmission mount which was gone. i had it replaced a few days ago and now the clunk is getting worse. im getting ready to drive this thing into the lake and the clunk is driving me crazy

help!!!!
