Installation Notes and Tips

Verify the shaft diameter, outside diameter, and width before installation to confirm the seal matches the transmission housing and output shaft. Clean the sealing bore and shaft surface thoroughly, and inspect for grooves, corrosion, or damage that could affect sealing performance. Confirm side and transmission notes before ordering, especially on applications such as the Ford Fusion with Aisin F21 transmission.

For fitment-specific service, use the vehicle listing to match year, make, model, and position exactly. SKF 16908A is listed for left and right positions depending on application, so side identification matters during replacement.
