Got a '96 2500, Cummins, 4x4 and I'm having some steering problems.  The
truck has far too much play in the steering.  The truck will grab
imperfections in the road and pull the truck along those imperfections.
Reminds me of a vehicle with bad ball joints.  Has made for some
"interesting" rides.

I took the truck to a Dodge dealer.  The dealer replaced some bushings
that held the front spindle assy to the axle.  Minor improvement but no
material change in ride quality.

I replaced the tires with Bridgestone dualer A/T's and changed the
steering shaft.  Minor improvement but no material change in ride quality.

Took the truck to another Dodge dealer.  Replaced the steering gearbox,
stabilizer and track bar.  Minor improvement but no material change in
ride quality.

Is there something these mechanics and I am missing?  I'm seriously
stumped - any ideas really appreciated.
