BUSHING INSPECTION

Inspect the steering knuckles, king pins, steering
arms and tie rod arms and replace if indications
of weakness, cracks or excessive wear are
found. Cracks can be located by dye check,
magnetic
particle
or
fluorescent
particle
inspection performed by a qualified technician.
b.
Check spindle bearing diameters for size and
condition. Replace spindle if bearing diameters
are under wear limits, discolored from heat or
severely scored.

If tie rod arm or steering arm has been removed,
inspect tapers for fretting pits. If the tapered
hole in the knuckle is fretted and pitted replace
both the knuckle and the arm. If only the arm
taper is fretted, replace only the arm.
d.
If the king pin has worn through the bushing and
into the knuckle, replace the knuckle.
