The real issue with the grease and corn head flavor and a lot of others is that many don't mix and match.
When switching to a different style, flavor, lithium vs polyurea grease situation you should always fully clean out the old before adding the new.
Unless you are 100% sure they are compatible.
Otherwise you will get this
"
When I restored the truck I added a bunch of corn head grease to the box, but it kind of congealed with the old grease in there and man, what a mess! "
This is the right way " Anyway I got everything squeaky clean and got a rebuild kit"
Sounds like midlifer is off to the races in a good way with his project.
