Powertrain Mount Balancing

Powertrain Mount Balancing

Note:
Follow the balance procedure steps listed below when no starting point has been established such as in a collision repair.

1. Raise and support the vehicle. Refer to Lifting and Jacking the Vehicle Service and Repair.





2. Loosen the front transaxle mount through bolt (1) until it is finger tight.





3. Loosen the rear transaxle mount (1) through bolt until it is finger tight.

4. Lower the vehicle.





5. Position two floor jacks with wood blocks under the engine and transaxle in order to support the powertrain assembly.





6. Loosen the transaxle adapter to transaxle bolts (1).





7. Loosen the engine mount (1) to bracket bolts (2).

8. Lower the floor jacks in order to allow a 1/4 inch (6 mm) gap between the upper engine mount and engine mount bracket, and also between the transmission and left transmission mount.





9. Check that the front and rear mounts are centered (1) in the mount brackets, adjust if necessary.

10. Tighten the left hand (transaxle side) mount bolts, starting with the bolt nearest to the center of the mount. See the appropriate transmission mount replacement procedure for the fastener tightening specifications.





11. Tighten the right hand (engine side) mount bolts (1), starting with the bolt nearest to the center of the mount. See the appropriate engine mount replacement procedure for the fastener tightening specifications.

12. Remove the floor jacks from under the oil pan and transmission.

13. Raise the vehicle.

14. Shake the powertrain from front to rear and allow the powertrain to settle.





Note:
It is essential that the lower mount through bolts should be as close to centered as possible in the oversized mount insert holes before tightening to specification.

15. Tighten the rear transaxle mount through bolt (1). See the appropriate transmission mount replacement procedure for the fastener tightening specifications.





16. Tighten the front transaxle mount through bolt (1). See the appropriate transmission mount replacement procedure for the fastener tightening specifications.

17. Lower the vehicle.
