Symptom Possible Cause Action rear drive halfshaft
Wheel bearings, brakes or
suspension components Vibration at highway speeds
Out-of-balance wheel(s) or tire(s)
Driveline out of
balance/misalignment
Driveshaft center bearing touching
body mounting point
Balance and install new wheel(s) and tire(s)
as required
REFER to: Wheel and Tire (204-04 Wheels and Tires, Removal and Installation).
For additional information,
REFER to: Driveline Angle Inspection (205-00 Driveline System - General Information,
General Procedures).
Refer to the Manufacturer approved
diagnostic system for driveshaft balancing
application
Check for correct spacer washer thickness.
Inspect and install new washers as required Shudder, Vibration During
Acceleration
Powertrain/driveline misalignment
High constant velocity (CV) joint
operating angles caused by
incorrect ride height
Check for misalignment. Install new
components as required. For driveshaft
alignment,
REFER to: Driveline Angle Inspection (205-00 Driveline System - General Information,
General Procedures).
Check the ride height and verify the correct
spring rate. Install new components as
required Lubricant Leak
Rear drive axle breather
Damaged seal
Rear drive axle filler plug
Rear drive axle rear cover joint
Check oil level and correct as required
Install new components as required Pinpoint Tests
PINPOINT TEST A : EXCESSIVE DRIVELINE NOISE TEST
CONDITIONS DETAILS/RESULTS/ACTIONS A1: CHECK NOISE FROM VEHICLE ON ROAD TEST 1 Road test vehicle to determine load and speed conditions when noise occurs. 2 Assess the noise with different gears selected. Does the noise occur in different gears at the same vehicle speed? Yes
Install a new rear drive axle/differential assembly.
REFER to: Axle Assembly - V6 3.0L Petrol (205-02 Rear Drive Axle/Differential, Removal and Installation).
Re-test the system for normal operation.
No
Suspect the engine or transmission. For additional information, REFER to:
Engine - 3.0L/4.2L (303-00 Engine System - General Information, Diagnosis and Testing), Engine - 2.7L Diesel (303-00 Engine System - General Information, Diagnosis and Testing), Diagnostic Strategy (307-01A Automatic Transmission/Transaxle - V6 3.0L Petrol, Diagnosis and Testing).
1 Coolant drain plug 2 Torque converter access plug 3 Drive plate 4 Rear cover 5 Main bearing cap 6 Identification mark 7 Front cover 8 Front pulley The main bearing caps are made from cast iron and are cross bolted to increase rigidity. An identification mark on the bearing
cap faces the front of the engine.
At the front of the crankshaft, a tuned torsional vibration damper is incorporated into the crankshaft front pulley. At the rear of
the crankshaft a pressed steel drive plate, with a steel starter ring gear, is installed to transfer drive from the engine to the
transmission. The reluctor ring for the CKP (crankshaft position) sensor is integrated into the perimeter of the drive plate.
The crankshaft seals are located in the front and rear covers.
PISTONS AND CONNECTING RODS
The diameter of each piston is graded and precisely matched to each cylinder bore to help reduce noise. In the vertical plane,
the pistons have a slight barrel form, which helps to ensure a reliable oil film is maintained between the piston and the
cylinder bore. A solid film lubricant coating is applied to both reaction faces of the piston to reduce wear and improve fuel
economy.
A three-ring piston-sealing system is used. The steel top ring is treated with a PVD (physical vapor deposition) peripheral
coating. PVD is a coating technique where material can be deposited with improved properties to ensure good cylinder bore
compatibility and wear resistance. A Napier center ring helps cylinder pressure and oil management, while the three-piece oil
control lower ring is produced from nitrided steel.
The pistons are cooled with engine oil from four piston cooling jets installed under the valley of the cylinder block. Each piston
cooling jet sprays oil onto the underside of the two adjacent pistons, one from each cylinder bank.
The connecting rods are forged from high strength steel. The cap is fracture-split from the rod to ensure precision re-assembly
for bearing shell alignment. There are three grades of large end bearing available, each being color coded. For further
information refer to Engine - 5.0L, Vehicles Without: Supercharger - General Procedures.
Operating Temperature Range -40 to 160 °C (-40 to 320 °F) Oil Level Check
For additional information, refer to Engine Oil Draining and Filling (303-01A, General Procedures).
For accuracy, oil level checks should be performed with the vehicle on level ground when the oil is hot. The vehicle needs to
stand for approximately 10 minutes, after the engine is switched off, to allow the oil to drain back into the sump pan and the
oil level to stabilize. The oil level system will not give a reading until the oil level has stabilized.
With the ignition on, the engine stopped and the transmission in P (park), repeatedly press the trip button on the end of the
LH multifunction switch until the oil level icon and applicable message are displayed in the fuel gage/trip computer area of the message center, as shown below:
Item Description A Oil level is between 50% and 100% of recommended level. No top-up required. B Oil level is between 12.5% and 50% percent of recommended level. Add 0.5 liter (0.53 US quart) of oil. C Oil level is between 0% and 12.5% of recommended level. Add 1 liter (1.06 US quarts) of oil. D Oil level is above maximum for safe operation. Reduce oil level to recommended level. E Oil level is below minimum for safe operation. Add 1.5 liters (1.59 US quarts) of oil, then recheck level. F Oil level is stabilizing. Wait 10 minutes and then recheck level. If this display is accompanied by the message ENGINE OIL LEVEL MONITOR SYSTEM FAULT, a fault with the oil level monitoring system is indicated. System Fault Warning
If there is a fault with the system, in addition to being displayed during an oil level check, the message ENGINE OIL LEVEL
MONITOR SYSTEM FAULT will be temporarily displayed when the ignition is first switched on.
