I'm trying to do some lubing of the steering rack on my 2000 3cyl Merc 90. Problem is that when I put the grease gun into those fittings I am unable to pump any grease thru them into the rack. I've removed the fittings and verified that I can get grease thru them but when I put them back I still can't get the grease to go in. I'm thinking maybe I need to loosen those large nuts on the ends of the rack to relieve pressure so the new grease will push out the old grease. Any other suggestions? I tried uploading photos but I get errors during load process. they are not large images. So you';ll have to visualize what I'm talking about. Fortunately the rack is not messed up, this is just preventative maintenance.
