All. Hope everyone is well. I am not sure where to post this so here goes. I purchased on old Blazer that we are working to restore, revive. I noticed my steering is making noise and I wanted to grease it. I took my grease gun I use for my trailer axles and went to do the project and. noticed my grease gun won't fit these Zerks. They are a little larger. I have watched some Youtube videos on this and they all look like they are using the same size as the axles. Can anyone offer any pointers for what I might be looking at incorrectly? BTW. I have looked pretty closely any my steering setup and it does not have an obvious name on it like SeaStar. Thanks.
