Diagnosis and Remedy
These contact patterns, located on toe or heel on both
drive and coast sides, mean that 1) both pinion and
gear are defective, 2) carrier is not true and square, or
3) gear is not properly seated on differential case. The
remedy is to replace the defective member.
Irregular patterns: If the pattern is not oval, it means
that bevel gear is defective. High or low spots on tooth
surfaces or on the seat of bevel gear are the cause of
irregular patterns appearing on some teeth. The rem-
edy is to replace the pinion and-gear set and, if the
seat is defective, so is transfer case.
