Found my lovely alternator bracket oil seal.
On a 2005 4.8is (104k miles)
Yes you have to remove fan, alternator, unbolt power steering pump (leave high pressure line), remove front axles, unbolt front differential from engine.
No, you do not need to remove engine mounts or lift engine.
Old seal was nice, hard, sticky, and shrunken. Much like valve covers are and the seals in the transmission above the valve body.
