Before you adjust the box, make sure that the big nut that holds the
steering arm on the output shaft of the box is tight - it's common for this
to come loose, eventually wearing the splines if left too long.

Reach under the car, rest a finger on the nut and arm while someone moves
the wheel - any movement will be obvious.
