With the steering mechanism removed, adjust the tightening

of the worm bearings by means of the shims 4 (Fig. 59) installed

between the steering gear case and the case lower cover. When

the worm bearings are tightened correctly the force required for

turning the steering wheel (without the steering arm shaft)

should be in a range of 2.2-4.4 N (0.22-0.45 kgf).

Adjust the meshing of the roller with the worm without

removing the steering mechanism from the automobile (having

only disconnect the drag link from the steering arm) by shifting

the steering arm shaft with the aid of the adjusting screw 21

provided on the side cover of the steering gear case. Upon

adjustment, the steering wheel should be freely turned from the

middle position corresponding to a straight-ahead movement

when a force of 8.8 - 15.7 N (0.9-1.6 kgf) is applied to the

steering wheel.
