I changed outer tie rod ends on my '96 Concorde yesterday, but now my wife feels the car is out of alignment and handling erratically. I was pretty careful to mark and count threads/turns, etc., but I'm sure it doesn't take much to throw things out by a few degrees.
Overall, this should be a pretty easy job - but the driver side was very tough to turn in and out of the sleeve, passenger side was much easier. I paid $20.99 each for TRW replacement tie rod ends (no grease fittings, but a slightly bigger head than stock).
I'm taking it in for an alignment today - $69.99 if it needs 4 wheel alignment, $59.99 if only the fronts.
