Pinion/Clutch Check

WARNING: This page is about a different car, the 2003 Nissan Altima. However, it is still accessible from the selected car via links, so may be relevant.
  1. Inspect pinion assembly teeth.
    • Replace pinion assembly if teeth are worn or damaged. (Also check condition of ring gear teeth.)
  2. Inspect planetary gears/planetary gear teeth.
    • Replace planetary gears/planet gears if teeth are worn or damaged. (Also check condition of pinion shaft/drive shaft gear teeth.)
  3. Check to see if pinion assembly locks in one direction and rotates smoothly in the opposite direction.
    • If it locks or rotates in both directions, or if unusual resistance is evident, replace.
