2. Inspect worm bearings and
cups for damage or excessive
wear. Replace bearings if nec-
essary. The lower worm bearing
cup is not replaced separately,
but is serviced with the worm
bearing adjuster. If upper worm
bearing cup is defective, drive
cup out of housing with a punch
and install new cup using Instal-
ler J-8811 with Driver Handle
J-8092.
3. Check fit of the pitman shaft
in the bushing in side cover. If
bushing is worn, side cover must
be replaced as bushing is not
serviced separately.
4. Inspect the worm and nut balls
and the grooves of worm and nut
for damage or excessive wear.
Replace parts as necessary.
5. Inspect teeth of ball nut and
pitman shaft for pitting or scor-
ing which would require replace-
ment of nut or pitman shaft.
