straight downward when installed.
8. When installing grease seal guard, adjust so painted surface is
visible.
Install knuckle ¯ange stopper bolt and nut on stopper side of
axle case.
After installing tie rod, adjust it to speci®ed steering angle
using turning radius gauge, then tighten with lock nut.
