I'm stuck getting my new steering rack installed. I pulled the old one off and removed the splined pinch top end of the rag joint with the rack. I dissembled the rag joint and cannot get the top end to slide back up the splined rod that comes down from the steering column. I'm assuming i must have damaged the end of the splined rod which is causing me difficulty getting the pinch to slide back up the rod. I can't really see any damage but I did bang it a few times trying to get the rack out. Any tips would be greatly appreciated.
