Removal Procedure
Notice: Do not strike or drop the propeller shaft, or allow the universal joints
to bend to extreme angles, as internal joint damage might occur.
Important: The two-piece propeller shaft and the support bearing used with the
3800 (VIN K) engine are not serviceable separately. The propeller
shaft and the support bearing should be replaced as a complete assembly
only.
- Raise and support the vehicle. Refer to
Lifting and Jacking the Vehicle
in General Information.
- Mark the relationship
of the propeller shaft (2) to the pinion gear yoke (1).
- Place an adjustable stand under the propeller shaft near the support
bearing in order to support the propeller shaft.
- Remove the bolts (4) from
the support bearing (3).
- Remove the following components from the torque arm (2):
• | The support bearing (3) |
- Remove the propeller shaft
bolts (2).
- Remove the propeller shaft retainers (1).
Important: Support the propeller shaft during removal.
- Perform the following
steps in order to remove the propeller shaft:
8.1. | Withdraw the slip yoke (3) from the transmission. |
8.2. | Move the propeller shaft (1 and 4) rearward and pass the propeller
shaft under the housing (2). |
If the bearing caps are loose, tape the bearing caps together in order
to prevent the loss of the needle roller bearings.
- Inspect the transmission output shaft splines for burrs.
- Inspect the outer diameter
of the slip yoke (1) for burrs.
- Inspect the splines of the slip yoke for the following conditions:
- Inspect the relationship of the splines of the slip yoke to the
transmission output shaft splines. The splines of the slip yoke must meet
the following conditions:
• | The slip yoke splines and the transmission output shaft splines
are of equal number. |
• | The slip yoke splines and the transmission output shaft splines
must engage properly. |
- Inspect the pinion gear
yoke (1) at the universal joint cap mating surface for the following conditions:
- If the mating surface of the pinion gear yoke exhibits the above
conditions, repair or replace the pinion gear yoke. Refer to
Drive Pinion Flange/Yoke and/or Oil Seal Replacement
in Rear
Drive Axle.
Installation Procedure
Notice: The propeller shaft must be supported carefully during handling to avoid
jamming or bending of parts.
- Lubricate the slip yoke with chassis lubricant.
- Install the slip yoke to the transmission output shaft.
- Place the center of the propeller shaft on the adjustable stand
in order to support the propeller shaft.
Important: Align the reference marks on the propeller shaft with the reference
marks on the pinion yoke to ensure the proper propeller shaft and pinion yoke
relationship.
- Install the rear of the
propeller shaft (2) to the pinion gear yoke (1).
- Install the rear universal joint to the pinion gear yoke.
Ensure that the bearing caps are properly seated.
- Install the propeller
shaft retainers (1).
Notice: Use the correct fastener in the correct location. Replacement fasteners
must be the correct part number for that application. Fasteners requiring
replacement or fasteners requiring the use of thread locking compound or sealant
are identified in the service procedure. Do not use paints, lubricants, or
corrosion inhibitors on fasteners or fastener joint surfaces unless specified.
These coatings affect fastener torque and joint clamping force and may damage
the fastener. Use the correct tightening sequence and specifications when
installing fasteners in order to avoid damage to parts and systems.
- Install the propeller
shaft bolts (2).
Tighten
Tighten the propeller shaft bolts evenly to 22 N·m (16 lb ft).
- Install the following
components to the torque arm (2):
• | The support bearing (3) |
• | Install the bolts (4) to the support bearing |
Tighten
Tighten the propeller shaft support bearing bolts to 50 N·m
(37 lb ft).
- Remove the adjustable stand from under the propeller shaft.
- Lower the vehicle.
