Breathe Easier

This bulletin applies to 2009-2015 Toyota Land Cruisers. Toyota strongly recommends that the breather plug be replaced whenever servicing any differential/transfer case to prevent possible repeat failures.

The subsequent use of the original breather plug after a repair has been found to contribute to the failure of the differential/transfer case components.
