High/Low Planetary Carrier
WARNING: This page is about a different variant/trim than selected.
- Clean the high/low planetary carrier in cleaning solvent. Do not disassemble the planetary carrier.
- Air dry and ensure all cleaning solvent is removed from the bearings in the planetary gears (3). Do not spin the planetary gears with compressed air.
- Inspect the planetary gears for chipped teeth.
- Inspect the planetary gears for debris embedded in the root of the teeth.
- Inspect for a washer (4) being on each side of the planetary gears.
- Inspect the low range teeth (1) for damage or excessive wear.
- Inspect the thrust washer surface (2) for scoring or excessive wear.
- Replace the high/low planetary carrier if any of the above conditions are found.
IMPORTANT:
Depending on the version of the transfer case, it may have either a 3 pinion gear or 6 pinion gear planetary carrier assembly. The 3 pinion gear planetary carrier is used with transmission RPO M30 and the input gear splines are 27 teeth. The 6 pinion gear planetary carrier is used with transmission RPO MT1 and MN8 and the input gear splines are 32 teeth. The repair procedures are the same for both planetary carriers.
