I have recently bought a 1999 406 Estate (Diesel Executive 110
version).  There is one irritating issue with it.  It pulls in to the
left.  So far I've had a 4 wheel alignment done on it and the vendor
*says* he has changed the wheels about without any change whatever.

The car has had a fairly adventurous life and appears to have been used
by someone like a vet, as it has obviously spent a lot of its time on
un-metalled roads.  I checked the steering when choosing the car and
this problem was not present at the time.  However the front coil
springs had to be replaced as well as some of the rear links and the
rear discs.

There doesn't appear to be any evidence of accident damage leading to
distortion of the car (at least to my fairly experienced DIY eye).  The
problem is there under load and with the clutch out.

Characteristically, if you take your hands off the wheel on a straight
stretch, the car begins to pull left immediately, eventually setting
itself to a turn of about 4 or 5 degrees.  On a curve on the A19 this
afternoon, I found that the car "set" itself quite happily and followed
it round until the angle of turn changed.  It runs happily up the
camber on a wrongly cambered straight piece of road nearby, and will
pull in against gale force cross winds.

Help!!!
