Scheme 1

Scheme 2

Begin the system diagnosis by reviewing the Driveline Disassembled Views and Driveline Support Assembly Description information. Reviewing the Description and Operation information will help you determine the correct symptom diagnostic procedure when a malfunction exists. Reviewing the Description and Operation information will also help you determine if the condition described by the customer is normal operation. Refer to Symptoms - Propeller Shaft in order to identify the correct procedure for diagnosing the system and where the procedure is located.

Strategy Based Diagnostics

Review the system operations in order to familiarize yourself with the system functions. Refer to Driveline Disassembled Views and Driveline Support Assembly Description . All diagnosis on a vehicle should follow a logical process. Strategy based diagnostics is a uniform approach for repairing all systems. The diagnostic flow should always be used in order to resolve a system condition. The diagnostic flow is the place to start when repairs are necessary. For a detailed explanation, refer to Strategy Based Diagnosis .

Visual/Physical Inspection

1. Inspect for aftermarket devices, which could affect the operation of the vehicle. Refer to «Checking Aftermarket Accessories»(/cadillac/xlr/i-2003-2009/remont/body-electrical/#how-to-diagnosis-repair-the-wiring-systems-testing__checking-aftermarket-accessories) .
2. Inspect the easily accessible or visible system components for obvious damage or conditions, which could cause the symptom.
3. Verify the exact operating conditions under which the concern exists. Note factors such as vehicle speed, road conditions, ambient temperature, and other specifics.
4. Compare driving characteristics or sounds, if applicable, to a known good vehicle and make sure you are not trying to correct a normal condition.

Intermittent

Text the vehicle under the same conditions that the customer reported in order to verify the system is operating properly.

Driveline Support Assembly Cleaning and Inspection

Tools Required

J 7872 Magnetic Base Dial Indicator Set. See Special Tools .

1. Clean all bolts and bolt holes of threadlocking material.
2. Clean the components in solvent.
3. Dry the components with compressed air.
4. Inspect the hub for the following conditions: Damaged bolt hole threads (1) Damaged snap ring grooves (2) Worn splines (3) Worn or scored surface (4) Worn or damaged bushing
5. Inspect the couplings for the following conditions: Loose or damaged inserts (1) Worn, cracking, or deteriorated rubber (2) MINOR cracking of the rubber is normal and acceptable. If the cracks expose any frayed fabric or internal windings, replace the coupling.
6. Inspect the propeller shaft for the following conditions: Damaged bolt hole threads (1) Loose or missing balance weights (2) Balance weights may have been installed and removed during the balancing process. In those cases, a weld mark will remain on the propeller tube. Inspect the inside of the driveline support tube for a missing balance weight. Dented or damaged propeller shaft tube (3) Worn, bent, loose, or damaged pins (4)
7. Inspect the propeller shaft pins for proper installation. The pin should extend beyond the flange 30 mm (1.18 in).
8. Measure the propeller shaft runout. Mount the propeller shaft in wooden V-blocks or between centers on a fixture. Inspect the runout of the propeller shaft in multiple locations, including the barrel ends, using the J 7872 . See «Special Tools»(/cadillac/xlr/i-2003-2009/remont/driveshaft-universal-joints/#propeller-shaft__special-tools) . If propeller shaft runout exceeds 0.3 mm (0.118 in), the propeller shaft is bent and should be replaced.
9. Inspect the flex plate spindle for the following conditions: Damaged bolt hole threads (1) Damaged snap ring grooves (2) Worn or damaged splines (3) Damaged threads (4)
10. Inspect the input hub for the following conditions: Worn or damaged splines (1) Damaged bolt hole threads (2)
11. Inspect the bearing housing for the following conditions: Damaged O-ring or snap ring grooves (1-2) Damaged threads (3) Worn or scored bearing bores

Rear Bearing Housing Assembly

1. Lubricate the NEW rear bearing housing O-rings (1) with clean engine oil.
2. Install the O-rings into the rear bearing housing.
3. Install the bearing (1) into the housing.
4. Position the rear bearing housing (2) into a press in order to install the bearing (1).
5. Install the snap ring (1) into the rear bearing housing.
6. Install the bearing (2) and snap rings (1) onto the flex plate spindle (3).
7. Install the flex plate spindle, with bearing, into the rear bearing housing.
8. Press the flex plate spindle, with bearing (1), into the housing (2). Support the inner race of the housing bearing when assembling the components.
9. Install the hub (1) onto the flex plate spindle. Align the marks on the flex plate spindle and hub for proper assembly.
10. Apply threadlock GM P/N 12345382 (Canadian P/N 10953489), or equivalent, to the threads of the spindle.
11. Install the nut (1) to the flex plate spindle. Tighten: Tighten the spindle nut to 90 N.m (66 lb ft).

1. Install a NEW bushing (1) into the propeller shaft, if required.
2. Inspect the bushing for proper installation. A properly installed bushing will protrude 18 mm (0.708 in) from the face of the hub.
3. Install the rear bearing housing assembly, bolts, and washers to the rear coupling. Tighten: Tighten the coupling bolts to 70 N.m (52 lb ft).
4. Install the bearing (1) onto the input shaft. Install the bearing until completely seated against the flange of the input shaft.
5. Install the snap ring (2) into the groove of the input shaft.
6. Install a NEW slinger washer (1) onto the input shaft. A properly installed slinger washer will have a gap of 1.5-2.5 mm (0.050-0.098 in) between the washer and the bearing face.
7. Install the input shaft, bolts, and washers to the coupling. Tighten: Tighten the coupling bolts to 70 N.m (52 lb ft).
8. Measure the distance (1) from the end of the input shaft to the flange on the bearing housing - automatic transmission. Record the amount as distance 1.
9. Measure the distance (2) from the driveline tube front bell housing flange to the bearing housing flange. Record this as distance 2.
10. Subtract the distance 2 from distance 1.
11. Record the computation as distance 3.
12. Lubricate the NEW driveline tube O-ring (1) with clean engine oil.
13. Install the O-ring into the front of the driveline tube.
14. Install the propeller shaft assembly into the driveline tube. During installation, lift the front of the input shaft to avoid damage to the slinger washer. Using a punch, tap evenly on the flat flange area of the rear bearing housing and install the assembly completely into the tube.
15. Install the rear bearing housing bolt hole plugs (1-3).
16. Install the snap ring into the driveline tube. The beveled edge of the snap ring faces the rear of the driveline tube assembly and will seat completely into the groove of the housing.
17. Measure the distance from the end of the input shaft to the driveline tube front bell housing flange. The actual distance must be equal to or within 2 mm (0.079 in) of the recorded dimension 3. If the actual distance is not within specifications, use a heat gun and heat the outside of the driveline support tube at the front bearing location. Tap on the rear of the propeller shaft assembly or pull on the input shaft until the shaft has reached the proper position.
18. Install the flex plate and bolts. Tighten: Tighten the flex plate bolts to 50 N.m (37 lb ft).

Scheme 3

The driveline support assembly consists of a driveline support tube, with rear bell housing, and an internal propeller shaft assembly. The front of the driveline assembly mounts to the engine bell housing. The driveline support assembly is specific for each vehicle, as equipped.

Scheme 4

The automatic transmission propeller shaft assembly consists of a splined front input shaft, front coupling, propeller shaft, rear coupling, M10 bolts, and a bearing and housing assembly. The input shaft, propeller shaft, couplings and bearing and housing assembly are balanced as an assembly. The front of the propeller shaft assembly is supported, at the input shaft, by a ball type bearing. An O-ring, located in the front of the driveline support tube, prevents the front bearing outer race from spinning. The rear of the propeller shaft assembly is supported by a bearing and housing assembly. The bearing and housing assembly consists of a housing, internally splined input hub, externally splined flex plate spindle, O-rings, snap rings, and 2 ball type bearings. The propeller shaft assembly is retained in the driveline tube by an internal snap ring. The torque converter flex plate is retained to the flex plate spindle by bolts and is mated to the torque converter.
