I want to change the seal between the basket drive shaft and the vertical tube attached to the frame through which the shaft passes.

Here is the part

Whirlpool WP8577376 Seal - AppliancePartsPros.com

My old seal was so degraded that I couldn't see how it was in place. There is a lip at the top of the tube from the frame that is about 1/16" below the top of the tube. Does the new seal just sit in this very shallow space or is it somehow supposed to be installed from the inside underneath the lip which would require taking out the transmission and the basket drive assembly.

Thanks for any input.
