Removal Procedure
- Raise and support the vehicle. Lifting and Jacking the Vehicle
Using a paint pen or a suitable marker, mark the relationship of the propeller shaft (2) to the differential carrier assembly (3). This will be used as a visual reference for proper engagement location after re-installation.
Using a paint pen or a suitable marker, mark the relationship of the propeller shaft (2) to the power transfer unit (3). This will be used as a visual reference for proper engagement location after re-installation.
- Support the front of the differential carrier assembly with a jack stand.
Differential Carrier Front Bolt (1) - Remove
- Lower the front of the differential carrier assembly to provide additional clearance between the propeller shaft and the fuel tank.
- CAUTION:
Use only the GM Special Tools Specified to remove the Propeller Shaft from the Differential Carrier Assembly. Prying on these components with any other tools may cause damage to either part which will result in improper performance or future failure.
Note the correct location of the propeller shaft service groove (1) prior to installing the DT-51329-A Drive Shaft Remover Adapter.
- CAUTION:
When removing the propeller shaft, DO NOT pry against the rear differential module slinger. Prying against the rear differential module slinger may cause damage to the slinger, which will result in unnecessary replacement of the rear differential module slinger.
NOTE:The 5/16" - 18 x 3.5" bolts included with the tool are to be used for this application.
Install the DT-51329-A Drive Shaft Remover Adapter (1) at the service groove (2) located on the propeller shaft.
Install the GE-2619-A Slide Hammer (2) to the DT-51329-A Drive Shaft Remover Adapter (1).
Using the GE-2619-A Slide Hammer (2) and the DT-51329-A Drive Shaft Remover Adapter, separate the propeller shaft (1) from the rear differential carrier assembly (2).
- Remove the GE-2619-A Slide Hammer (2) and the DT-51329-A Drive Shaft Remover Adapter (1).
Differential Carrier Front Bolt (1) - Loosely install
- Using a suitable jack stand, support the propeller shaft.
Note the correct location of the propeller shaft service groove (1) prior to installing the DT-51329-A Drive Shaft Remover Adapter.
- CAUTION:
When removing the propeller shaft, DO NOT pry against the power transfer unit. The power transfer unit will be damaged if it is pried against, which will result in unnecessary replacement of the power transfer unit.
NOTE:The 5/16" - 18 x 3.5" bolts included with the tool are to be used for this application.
Install the DT-51329-A Drive Shaft Remover Adapter (1) at the service groove (2) located just forward of the propeller shaft bearing bracket.
Install the GE-2619-A Slide Hammer (2) to the DT-51329-A Drive Shaft Remover Adapter (1).
- CAUTION:
Use only the GM Special Tools Specified to remove the Propeller Shaft from the Differential Carrier Assembly. Prying on these components with any other tools may cause damage to either part which will result in improper performance or future failure.
Using the GE-2619-A Slide Hammer and the DT-51329-A Drive Shaft Remover Adapter, separate the propeller shaft (1) from the power transfer unit (2).
- Remove the GE-2619-A Slide Hammer and the DT-51329-A Drive Shaft Remover Adapter.
Rear Propeller Shaft Bearing Bracket Bolt (1) - Remove [2x]
- CAUTION:
When servicing the propeller shaft, support both ends of the propeller shaft evenly to limit the movement of propeller shaft joints to a maximum of 10 degrees. Do not let the propeller shaft hang unsupported at any time, as it will cause damage to the propeller shaft boots
NOTE:Due to the weight and length of the propeller shaft, not allowing excessive movement of the joints may be difficult during removal and installation. It is recommended to use the aid of an assistant to remove and install the propeller shaft.
