2000 Concorde LXi Achille's Heel?

What tends to fail on this model with a 3.2 L V6 engine in a frequency
greater than normal for cars of it's size? I vaguely remember hearing there
is a steering or front end vibration issue that develops in a higher than
normal frequency. My 1995 upper tie rod bushings were replaced around 75K
and I'm noticing a slight vibration in the 2000 at 58K. It may be a front
tire needing a weight adjustment but I'd like to get a little more feel for
other issues that may occur before I have Firestone look at those tires. The
list they give of "issues" a customer should address has little credibility
with me based on cross checks done with the factory manual and a mechanic I
respect.

 

Still driving my 2000 Concorde lxi 3.2 I have 168,000 miles on it now and runs like new. Replaced timing belt and water pump at 120,000 miles Radiator went bad at 150,000. Followed shortly after the fuel pump , well actually the fuel filter got clogged. Replaced that and nothing else is wrong with it. Regular oil changes and fluids of course. But runs strong.
