WARNING: This page is about a different car, the 2007 Isuzu i-370, 2007 GMC Canyon, and 2007 Chevrolet Colorado. However, it is still accessible from the selected car via links, so may be relevant.
- Clean the high/low planetary carrier (100) and the planetary low gear (102) in cleaning solvent. Do not disassemble the planetary carrier.
- Air dry and ensure all cleaning solvent is removed from the bearings in the pinion gears (108). Do not spin the pinion gears with compressed air.
- Inspect the pinion gears for chipped teeth.
- Inspect the pinion gears for debris embedded in the root of the teeth.
- Inspect the pinion gears for excessive side movement from worn bearings or shafts.
- Inspect the low range teeth (c) on the planetary low gear (102) for damage or excessive wear.
- Inspect the planetary low gear and planetary carrier teeth (b) for excessive wear.
- Inspect the thrust washer surface (a) for scoring or excessive wear.
- Replace the high/low planetary carrier if any of the above conditions are found. The planetary low gear is serviced only with the planetary carrier assembly.
- Inspect the planetary carrier bearing (114), the input shaft bearing (113) and the thrust bearing (106) for the following conditions:
- Scoring
- Pitting
- Brinelling
- Excessive wear
- Replace faulty bearings. Refer to Transfer Case Disassemble and Transfer Case Assemble .
