• Moisture intrusion around the driveline sealing surface
• Service issues on BMW manual transmissions and transfer cases with the specified fitment

Installation Notes and Tips

Confirm the housing bore, shaft diameter, and seal width before installation. The listed fitment includes applications such as Fits 2007-2012 BMW 335i, with Getrag 217 Transmission; Fits 2003-2014 Toyota 4Runner, with Aisin VF4AM Transfer Case; and Fits 2003-2010 Honda Civic, N/A. Clean the sealing surface thoroughly and inspect the shaft for grooves or damage before pressing in the new seal.

Because fitment varies by transmission code and transfer case version, verify the vehicle’s drivetrain configuration against the notes shown for each application before ordering WS473677.
