Steering Knuckle Removal.

c. Removing the Upper Grease Seal.

Use the following procedure if it is required to remove the

upper grease seal (fig, 9-6) from the knuckle.

NOTE

Do not remove the upper grease seal from

the steering knuckle unless replacement

is necessary, since the seal is usually ruined

upon removal. If not previously removed,

the brake assembly and the steering arm

must now be removed prior to positioning

the knuckle in the vise.

(f) position the upper knuckle boss (top end down) in a vise with soft metal jaws and lock

securely.

(2) With the top end of the knuckle held firmly in this position, insert a screwdriver or similar

tool between the knuckle counterbore and the seal case. Pry the seal out of the knuckle.

(3) Remove the knuckle from the vise for cleaning and inspection.
