LEFT: Use a punch to remove the plug in the back of the box. Once you have removed the plug, you can drive the bearing race out of the housing. Note that you drive the race out from the outside of the housing.

BELOW LEFT: Using a rather large shaft, drive the Pitman arm shaft bushings out of the housing. Then clean the housing thoroughly.

RIGHT: Moving back to the worm gear assembly, remove the two screws that attach the retaining clip to the worm gear.

BELOW RIGHT: Now remove the metal tubes in the top of the worm gear and separate them. You can now clean these as well because you will be reusing them. Once the tubes are out, you can dump all the ball bearings out of the worm gear assembly. Note how the worm gear goes onto the worm gear shaft. You will need to reassemble this the same way. Now you need to clean all of the parts to remove the old grease.
