Thom,
The gearbox is adjustable to a point. Look at your shop manual for the screw on
later boxes and a nut on the earlier ones on the top of the box right next to
the filler nut. There is a locking nut which you have to release to tighten the
screw. Similar to adjusting a valve rocker. This should take some slack out of
the steering. However if there is too much wear, you will have to have a
rebuild. The TRF does a wonderful job for about 600$. You will get a box that
is better than new.
Good luck,
