5. Remove circular clip from shaft.
6. Remove boot from shaft.
ASSEMBLY
1. While rotating ball cage, clean old grease on joint sub-assembly with paper waste.
2. Fill serration slot joint sub-assembly (1) with NISSAN genuine grease or equivalent until the serration slot and ball groove
become full to the brim.
CAUTION:
After applying grease, use a shop cloth to wipe off old
grease that has oozed out.
