SYMPTOM/CONDITION

A shudder which occurs between 5 and 15 miles per hour on light acceleration, rather than under heavy throttle acceleration, and is more apparent with more than one passenger in the car.

DIAGNOSIS

Use the following procedure to verify the condition:

1. Road test the vehicle. This condition cannot be properly diagnosed on a hoist.

2. Verify that the condition occurs between 5 and 15 miles per hour and is present in drive only. This condition is very speed sensitive, and is most noticeably felt as a side-toside (not torsional) shake of the vehicle.

3. In an area where space and safety permits, perform full lock tight circle turns in both directions, in drive and reverse, to verify that the engine mount grounding and CV joint tripod bottoming is not the cause.

NOTE: OTHER CONTRIBUTING FACTORS TO THIS CONDITION MAY BE:

1. RADIAL AND LATERAL RUNOUT OF THE FRONT TIRES MISFIT, EXCESSIVE FRICTION, OR WEAR OF THE INNER CV JOINTS.

2. EXCESSIVE TRANSFER SHAFT RUNOUT IN THE TRANSAXLE.

PARTS REQUIRED

1 Intermediate Driveshaft Bearing Mounting PN 4504007
Bracket Kit
REPAIR PROCEDURE

This procedure outlines the replacement of intermediate driveshaft bearing mounting bracket and mounting bolts.

Under no circumstances should spacers of any kind be used to reposition the existing bracket to another position. Even with longer bolts, this could result in loss of bolt retention and driveshaft separation from the vehicle.

1. Disconnect battery and raise vehicle on hoist. Remove and discard the two bolts retaining the mounting bracket to the engine.

2. While holding the driveshaft in place, rotate the bracket to expose the two bolts which secure the bearing to the bracket.

3. Remove the two bolts and discard the bracket. Position the new bracket from the kit to the bearing and install the mounting bolts loosely.

4. Secure the bracket to the engine, using the two new mounting bolts from the kit. Torque the bolts to 54 N-m (40 ft.lbs.).

5. Push intermediate shaft into transaxle as far as possible. While holding in this position, torque the two bearing-to-bracket bolts to 28 N-m (21 ft. lbs.).

6. Lower vehicle and connect battery. Verify proper vehicle operation.
