Front suspension "clunk" '94 Concorde

My 94 Concorde with 137K miles is getting a bit tired but I need to keep in
running safely for a few more months so any suggestions will be appreciated.
It's the 3.3L V-6 if that matters.

I have a "clunk" that I hear and feel in the front suspension. It's hard to
reproduce but can be heard and felt while turning and hitting a large bump
like a speed bump in a parking lot. It feels like something is moving then
popping back into place. I had a "front end specialist" look it over and
all he could see was a worn tie rod end which he replaced. I can't see
anything loose or anything that shows signs of moving when it shouldn't.
The motor & transmission mounts look good. This clunk is noticible at low
speeds although the car handles fine otherwise - no shakes, no pulling,
straight, even braking, etc.

I had a similar problem a year ago and the mechanic found that a large nut
on one of the suspension arms had backed off about 6 turns which allowed the
arm to move. He assurres me that the nuts are tight now but I still have
the problem.

I'm concerned that I have an unsafe car on my hands despite what the
mechanic said. I'd appreciate your thoughts and ideas.

Best regards,

Dave
