9. Install kingpin in knuckle and axle beam. Tap kingpin
in place using hammer and brass drift if necessary.
Protect kingpins with a suitable material such as shim
stock.
Note: At this point in reassembly, check knuckle vertical play
and adjust if necessary.
10. Center steering components.
11. Mount dial indicator to steer beam and reference top
of the knuckle. Zero dial indicator.
12. Simulate axle loading with a jack and note dial indi-
cator reading.
Note: Floor jack can be used to wedge up steering knuckle.
13. Knuckle vertical play should be .002"- .012"
(.051 -.305 mm). Add or remove shims as necessary
to obtain correct end play. Center shims to prevent
damage during assembly.
14. When vertical play adjustment is correct, align draw
key opening and pin flat alignment.
15. Now install the new draw keys. Before the draw keys
are seated, we need to verify the bushing end-play is
between .001" - .008"
