nuts. Torque slotted hex nuts from 41 to 61 N·m (30 to 45 ft−lb) while
aligning ball joint hole with slot in nut. Insert cotter pins.
5. Remove caps or plugs placed during removal to prevent contamination.
6. Using tags placed during cylinder removal, correctly attach hydraulic hoses
to steering cylinder (see
Seal) (page 5–7)).
7. Lubricate cylinder ball joint grease fittings.
