A two-piece design front engine mount is currently being used for the vehicle applications listed above. A single thunk noise may be heard during the first few accelerations of the day from this type of mount, and is considered normal operation.

The mount has also been designed with more built-in free play that may be considered normal. The allowable free play (vertical movement) is 5mm.

If a shift shock condition is present when shifting from park into gear or between any combination of gears, the condition is due to transmission line pressure and not an indication of any movement of the mount.

If a whistle-type noise is heard, this is caused by a disconnected vacuum line.
