can anybody tell me the procedure for replacing the shift shaft seal in a 1993 alpha 1. Do i have to pull the leg off or just take the lower half off? Also , i had a dealer replace it for me last year but it still leaks. they told me that the plastic housing that the seal fits into probably needs replacing as well. I want to fix this myself this time but i am a little unsure whats involved. I have removed the leg and replaced before myself with no problems. So any input would be great Thks.
