Removal Procedure
Important: Observe the position of all of the driveline components. Accurately
mark the relationship of the following components before removal:
Reassemble all of the components in the exact relationship to each
other before removal. Follow the specifications, the torque values,
and any measurements that were obtained prior to disassembly.
- Raise and suitably support the vehicle. Refer to
Lifting and Jacking the Vehicle
in General Information.
- Accurately reference mark the propeller shaft.
- Remove the bolts from the rear of the pinion flange.
- Remove the retainers.
Notice: When removing the propeller shaft, do not attempt to remove the shaft
by pounding on the yoke ears or using a tool between the yoke and the universal
joint. If the propeller shaft is removed by using such means, the injection
joints may fracture and lead to premature failure of the joint.
- Remove the yoke and cross assembly.
- Tape the bearing cups in order to prevent the loss of bearing
rollers.
- Remove the propeller shaft by using the following procedure:
7.1. | Slide the propeller shaft forward. |
7.2. | Lower the propeller shaft. |
7.3. | Remove the shaft under the rear axle. |
Do not allow the universal joint to incline greatly; the joint may fracture.
- Clean all the parts using a suitable solvent.
- Inspect the outer diameter of the nylon injected yoke for burrs.
Burring damages the transmission seal.
- Inspect for proper installation and uniform seating of the bearing
cups.
- Inspect the slip yoke splines for wear.
- Inspect for twisted slip yoke splines or possibly the wrong universal
joint. Replace the parts as necessary.
Installation Procedure
- Install the propeller
shaft into the transmission.
Important: Install a new universal joint whenever a slip joint or companion flange
is serviced.
- Lubricate the slip joint.
- Install the yoke and cross assembly onto the pinion flange.
- Align the reference marks on the pinion flange and the propeller
shaft rear yoke. Seat the yoke properly.
- Install the retainers.
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 bolts
into the pinion flange.
Tighten
• | Tighten the rear pinion flange bolts to 20 N·m (15 lb ft)
for 2.2L engines. |
• | Tighten the bolts to 45 N·m (33 lb ft)
for 4.3L engines. |
