Isolating Vibration
WARNING: This page is about a different car, the 2009 Saturn Vue. However, it is still accessible from the selected car via links, so may be relevant.
NOTE:
Some engine/transmission combinations cannot be balanced in this manner due to restricted access or limited clearances between the torque converter bolts and the engine.
To isolate and correct a flywheel or torque converter vibration, separate the torque converter from the flywheel to determine if vibration is in the engine or transmission.
- With the engine at idle speed and the transmission in PARK or NEUTRAL, observe the vibration.
- Turn the engine OFF.
- Raise and suitably support the vehicle. Refer to Lifting and Jacking the Vehicle .
- Remove the torque converter access cover and the bolts (if equipped).
- Mark the relationship of the torque converter to the flywheel.
- Remove the bolts attaching the converter to the flywheel.
- Slide the torque converter away from the flywheel.
- Rotate the flywheel and torque converter to inspect for defects or missing balance weights.
- Lower the vehicle.
- With the engine at idle speed and the transmission in PARK or NEUTRAL, observe the vibration.
- Turn the engine OFF.
- If the vibration remains, the vibration is most likely caused by the engine.
- Install the converter to flywheel bolts and tighten to 60 N.m (44 lb ft).
- If the vibration is gone or changed, perform the Indexing Torque Converter procedure.
CAUTION:
Refer to Fastener Caution
.
CAUTION:
When installing the torque converter to the flywheel, make sure to use specific bolts. DO NOT use longer bolts. Using longer bolts will result in deformation of the torque converter cover and cause internal damage.
