You can Select Your Vehicle to check if 10064949 fits your vehicle.

To check the transaxle mount, raise the vehicle and secure it on jackstands. Observe the mount while an assistant manipulates the transaxle or use a pry bar to lever it up and down. If the rubber separates from the metal plate or if the case moves up but not down, replacement is necessary. If there is movement between the metal plate and its attachment point, tighten the bolts or nuts. For wear assessment of the forward transaxle mounting assembly insulator, insert a large screwdriver or prybar between the transaxle and the crossmember and attempt to lever the housing; movement indicates the insulator rubber is worn and requires replacement. The same procedure applies to the rear transaxle mounting assembly. For replacement, disconnect the cable from the negative battery terminal and support the transaxle with a jack. Remove the forward support bracket-to-transaxle bolts, the mount-to-support bracket nut, and the mount-to-cradle nuts, followed by the removal of the forward transaxle support bracket and the mount itself. Position the new mount and install the mount-to-cradle nuts finger tight, then place the transaxle support bracket and install the mount-to-support bracket nut and the bracket-to-transaxle bolts finger tight. Ensure all mounting hardware is loose, lower the jack until the transaxle centers the mount, and then tighten the hardware to the specified torque before reconnecting the negative battery cable. For the rear transaxle mount, repeat the disconnection of the negative battery cable and support the transaxle, then remove the rear support bracket-to-transaxle bolts, the mount-to-support bracket nut, and the mount-to-cradle bolt nuts, followed by the removal of the support bracket.

1. Raise the vehicle and support the engine and transaxle. 2. Remove the forward torque reaction strut bolt. 3. Remove both front and rear mounts simultaneously. 4. Install new mounts and tighten all nuts to the specified torque.

It signifies that the mount should be changed.

To check the transaxle mounts, raise the vehicle and secure it on jackstands. Then, observe the mount while an assistant manipulates the transaxle or use a pry bar to test for movement. If the rubber separates from the metal plate or if the case only moves up, replacement is necessary.
