and the switch.
Operation

larities in turning the steering continue even after making the
above adjustments, check the seats on which the ball bearings
rotate: replace them if they are recessed or if the balls are flat-
tened.

If the front suspension is noisy, check: the efficiency of the front
shock absorbers; the condition of the ball bearings and relevant
lock-nuts, the limit switch rubber buffers and the movement
bushings. In conclusion, check the tightening torque of the
wheel hub, the brake calliper, the shock absorber disk in the
attachment to the hub and the steering tube.
