Insert the 19 balls (29) one by one in one of the openings for the recirculating tubes located in the piston (48) while turning the spindle at the same time. Balls inserted in one opening should recirculate to the opposite opening as the ball screw is rotated. Before proceeding, make certain the balls are at an equal depth in both holes of the piston. (See Figure 38). This will assure correct installation of the return tube (49).
Install the seven remaining balls(29) into the ball return tube halves(49) using lithium base general purpose grease (Ford Chassis grease
NOTE: the utmost care must be taken with these steps. Incorrect assembly of this group may result in one or more balls failing inside the piston or coming out at the top of it and lodging in the bottom of the housing(45).

NOTE: Make certain to rotate the glide rings(46) so that their gaps are 180° apart and not in line with each other.
HOUSING ASSEMBLY
6.If the outer race of bearing(26) was removed, it must be reinstalled using tool 297677. Center the narrow bearing spacer on tool 297677 then install the bearing(26) complete with its outer race(26) on the tool. Drive the bearing and race along with the spacer into the housing from the output shaft side of the housing until the tool bottoms against the outside of the housing. (See Figures 41A, B & C) Remove the tool and check to be certain that the outer race and spacer have been driven into the housing sufficiently deep to allow installation of the snap ring(25). If the snap ring(25) cannot be installed, remove the narrow bearing spacer and using tool 297647 drive the bearing race further into the housing. Reinstall the narrow bearing spacer and install the snap ring(25), making certain it is completely seated in its groove. Using tool 297647 tap the outer race from inside the housing
