Just did mine a couple of weeks ago. The tin on the outboard joint didn't want to move for anything and I didn't want to mess it up so i just left. it. I however clean the joint. Wipe out as much grease as you can. I then used brake cleaner swished the joint around a bit and dumped it out. I did this several time and after a bit the joint was no longer showing signs of grease. I am sure some was stuck someplace.
When time to repack cut off just the tip of the grease pack. You can then stick the pack down in the joint and slide it between the carrier and the outer race of the joint. You can the squeeze the grease right in the joint. After doing that I used a small syringe that I go from the drug store. I cut the end off so the whole end was open. I filled the syringe with grease and then squirted it into the joint. This worked fairly well to get the grease down into the joint. Then once you can't get anymore to go that way just start poking at the grease. Poke, poke, poke it will eventually work its way into the joint. I got both packs of grease into the outboard and inboard joints using this method. I wish I had pictures but I am still cleaning frigging grease off my self.
