Driveshaft - Rear, One-Piece

Driveshaft - Rear, One-Piece













Removal

1. With the vehicle in NEUTRAL, position it on a hoist. For additional information, refer to Jacking and Lifting Service and Repair.

2. To maintain driveline balance, index-mark the driveshaft flange yoke and the pinion flange.





3. Index-mark the driveshaft yoke and the transmission tailshaft.





4. NOTE: These fasteners have an adhesive patch on the threads. New fasteners are required for installation.

Remove and discard the 4 driveshaft-to-pinion flange bolts.





5. NOTE: The driveshaft flange yoke fits tightly on the pinion flange pilot. Never hammer on the driveshaft or any of its components to disconnect the yoke from the flange. Pry only in the area shown, with a suitable tool, to disconnect the yoke from the flange.

Using a suitable pry bar, disconnect the driveshaft flange yoke from the pinion flange.





6. Lower the driveshaft and slide it off the output shaft.

Installation

1. Inspect the extension housing seal for damage. Install a new seal as necessary. For additional information, refer to Automatic Transaxle/Transmission - 4R70E/4R75E Extension Housing Seal or Automatic Transaxle/Transmission - TorqShift(R) Extension Housing Seal.





2. Lubricate the transmission output shaft spline with grease.





3. Check to see if a paint mark is present on the front of the driveshaft and on the end of the transmission output shaft.





4. NOTE: Depending on the paint markings, there are 2 methods of indexing the driveshaft and the output shaft.

Install the driveshaft.

1. Preferred method - align the factory-made paint marks on the output shaft and driveshaft and position the driveshaft in the transmission.

2. Alternate method - align the index marks that were created in the removal process and position the driveshaft in the transmission.









5. NOTE: The driveshaft flange yoke fits tightly on the pinion flange pilot. To make sure that the yoke seats squarely on the flange, tighten the bolts evenly in a cross pattern in the sequence shown.

Position the driveshaft flange yoke on the pinion flange with the index marks aligned and install 4 new driveshaft-to-pinion flange bolts.

- Tighten the 4 new bolts in the sequence shown to 112 Nm (83 lb-ft).
