3.5 Excessive steering wheel slop
If your steering wheel turns more than about 1/2-inch without moving
the drag link, then it should be tightened. On top of the steering box
at the end of the steering shaft there is a lock nut and adjusting screw.
While the preload of the worm shaft can be precisely set at 1.58 to
2.63 kg, it is not necessary to measure it. Tighten the adjusting screw
a little, and check the steering slop. Keep tightening and checking
it progressively until there is less than 1/2-inch of slop. Be very
careful not to overtighten it. Before driving, check the full travel
of the steering to make sure there aren't any stiff spots anywhere in
its travel, and loosen it if there are.
