Take-off Vibration
Background:
Take off vibrations at low speed, especially with high acceleration and/or heavy load, can occur in some cases.
Solution:
The level of vibration can be reduced by changing the vertical position of the center support bearing. Best results differ from car to
car. Start with a change of +6 mm (1/4 inch) upwards. If results are not acceptable, try other positions using a variation of -5 mm
(3/16 inch) downward to +12 mm (1/2 inch) upward from the ORIGINAL position.
NOTE:
Check to ensure that, if the vehicle is subject to the FUEL TANK CLEARANCE RECALL (SMB 23-23; May '90 -
Recall 55), the required inspection and/or service have been performed prior to performing this repair.
IMPORTANT:
The clearance between the driveshaft and fuel lines must be at least 20 mm. Clearance between driveshaft and fuel tank
must be at least 16 mm. Final inspection must be performed at correct vehicle road height, with vehicle either on drive-on
lift or on ground level. Shimming upwards should not exceed +12 mm (1/2 inch). After re-positioning, the center support
bearing housing should not contact floor pan.
