Place gear housing in a vise with Worm shaft bore horizontal and side cover opening facing up. With sector shaft and worm shaft seals, sector shaft bushings, and worm shaft bearing races installed, and ball nut assembly together, proceed as follows: On all vertical sector shaft gears, proceed to step 2). On horizontal sector shaft gears, slip upper ball bearing over worm shaft and insert worm and nut assembly into housing feeding end of shaft through upper ball bearing race and seal. Place ball bearing in adjuster race and press stamped retainer into place with suitable socket. Install adjuster and lock nut into housing carefully guiding worm shaft into bearing until nearly all end play is removed from worm shaft.
On vertical sector shaft gears, place worm shaft bearing in housing race. Slide other bearing and adjuster plug assembly over upper end of worm shaft. Insert worm shaft, nut and adjuster assembly into housing while guiding lower end of worm into housing bearing. Thread adjuster into housing until nearly all end play is removed from worm shaft.

Fig 1: Checking Lash Adjuster Clearance
Courtesy of NOT AVAILABLE
With all models, position lash adjuster (with shim) in slotted end of sector shaft. Check end clearance which should not be more than 0.002" (see Fig 1). If clearance is greater than 0.002", a steering gear lash adjuster shim kit is available. Kit contains shims of 0.063", 0.065", 0.067" and 0.069" thick. Lubricate gear as follows: Rotate worm until ball nut is at end of travel while forcing as much grease as possible into housing without losing it out sector shaft opening. Rotate worm until ball is at other end and apply more lubricant.
Rotate worm until ball nut is in center of worm; this will help sector and ball nut engage properly. Insert sector shaft and lash adjuster screw (without side cover) into housing so center tooth of sector enters center tooth space in ball nut. Apply more lubricant into housing. Install side cover gasket. Install side cover over sector shaft by reaching through cover with a screwdriver and turning lash adjuster screw counterclockwise until screw bottoms; then, back screw off one-half turn. Loosely install a new lock nut onto adjuster screw. Install and tighten side cover bolts to specifications.
NOTE: If new side cover bolts are used, they must be specified, self-locking bolts.

Adjust worm bearing preload and over-center preload as previously outlined in Adjustments.
