There should be a light coat of grease on the bearing retainer shaft. I've also put a light film on the splines before. That part did not seem to make any difference one way or the other. I suppose it might help with installation just a hair.
Thanks for the fast reply. I want to do this today because it is almost 60* outside. I was thinking of putting a light coat on the splines. I am going to have someone turn the slip yoke to help line the input shaft up.
Now I have a couple questions. I tried putting it in and it doesn't look like the throwout bearing is lined up with the clutch (about half inch to the right of it). Do I have to take the bellhousing off and line it back up or can I just try again. I don't want to take all the back off again.
