i have a 80 toy tcase in my zuki. i work at NAPA and looked up the front tcase seal for the output shaft. it just listed one. when i got the front flange off,,there is a felt seal in the front and a oil seal behind it. whats the point of the front seal?its just a piece of felt.also,can i replace the rear seal from the front,or do i need to remove the housing and install the seal from the rear? thanks
