Drive and Driven Gears Damaged

1. A scored, nicked, or gouged driven gear is usually indicative of improper gear mesh on those vehicles that have the drive gear integral with the output shaft. The output shaft should be carefully inspected for imperfections and replaced if necessary.
2. A driven gear with two or three adjoining teeth badly scored is indicative of improper assembly procedure. The gear should be inserted in the automatic transaxle while simultaneously turning the halfshafts. This will ensure initial gear engagement and prevent gear damage. Never use force.
3. Whenever a drive gear is replaced, a new driven gear should also be installed, regardless of its apparent condition.
