Another critical indicator is milky or creamy-looking gear lubricant when you drain it, which signifies water has entered the gearcase through a failed seal.\u003c\/p\u003e\u003c\/details\u003e\n\u003cdetails\u003e\u003csummary\u003eHow often should I replace this washer?\u003c\/summary\u003e\u003cp\u003eIt is highly recommended to use a new washer every time you remove the vent screw. This is most commonly done during a seasonal gear lubricant change.

The best method is to consult your engine's service manual or parts catalog to confirm the OEM part number is 27-49955 or 8M0077608.

If your number is the first in the new range (e.g., exactly 2B529482), this kit is correct. If your number is just before the break, you will likely need the previous part number.

This kit fits drives with serials between 2491586 and 0D469858. Second, check the vertical shaft. If there is a preload pin on the shaft, this kit is NOT compatible.
