Check for play in the wheel bearings:
1. Place stop wedges in front of and behind LH wheel and jack up RH
wheel.

3. If any play, support the wheel axle to prevent the trailer from falling
down from the jack.

the castellated nut (C) until a slight resistance in the wheel rotation
is felt.

vertical - is aligned with the cotter pin hole in the shaft.
6. Fit a new cotter pin and bend it.
