Differential Carrier Assembly Procedure
WARNING: This page is about a different car, the 2006 Pontiac Montana SV6 and 2006 Chevrolet Uplander. However, it is still accessible from the selected car via links, so may be relevant.
IMPORTANT:
- The transfer case is assembled for proper gear tooth clearances, backlash and bearing preloads with selective shims.
- Do not assemble the internal components dry. Lightly lubricate the bearing races, bearings, gears and oil seals with the proper lubricant. Components in the transaxle portion of the transfer case should be lubricated with DEXRON III GM P/N 12378470 (Canadian P/N 10952622) or equivalent. Components in the hypoid gear portion of the transfer case should be lubricated with GM P/N 12378514 (Canadian P/N 88901045).
- Install the needle bearings (4 and 6) and washer (5) to the gear (3), if required.
- Install the pin (9), gear (3) and washers (1, 2, 7 and 8) to the differential carrier, if required.
- Install the ring (10) to the carrier, if required.
- Install the side gears (2), pinion gears (3) and washers (1 and 4) to the carrier, if required.
- Install the shaft (1) and roll pin (2) to the carrier, if required.
- Determine if the drivenshaft has a plus, minus or zero value (1) etched onto the end of the gear.
If the drivenshaft has a plus, minus or zero value etched onto the gear end, refer to Extension Housing Assembly and Shim Selection - Procedure A .
- Determine if the drivenshaft has a 4 digit measured value (1) etched onto the end of the gear.
If the drivenshaft has a four-digit number etched onto the gear end, refer to Extension Housing Assembly and Shim Selection - Procedure B .
IMPORTANT:
A comma is to be considered a decimal point.
