There are three power train mounts: left and right engine mounts attached to the engine block and subframe, and a rear mount attached to the transmission and subframe. During the check, the engine must be raised slightly to remove the weight from the mounts. To do this, raise the vehicle and support it securely on jackstands, then remove the front wheels and tires. Position two jacks, one under the crankshaft pulley and the other under the transmission bellhousing, using a block of wood between the jack head and the crankshaft pulley or bellhousing, and carefully raise the engine/transmission just enough to take the weight off the mounts. The safest method is to use an engine support cradle that raises the engine from above, which can be rented at most tool rental shops. Check the mounts for any cracks, hardened rubber, or separation from the metal plates, as the rubber may sometimes split down the center. Also, check for relative movement between the mount brackets and the engine or subframe by using a large screwdriver or prybar to attempt to move the mounts; if movement is noted, lower the engine and tighten the mount fasteners. To replace the mounts, disconnect the cable from the negative terminal of the battery, then raise the vehicle and support it securely on jackstands. Remove the engine splash shield, then take out the bolts holding the engine mount to the subframe. Raise the engine until the engine mount bracket clears the subframe, then remove the bracket-to-mount bolt from above. Remove one engine mount and replace it with a new one, then replace the other front mount. Install the bolts, lower the engine, and tighten the bolts to the specified torque.
