Hey, if your Lincoln Navigator or Blackwood with the 5.4L V8 is having charging issues, this OEG Parts alternator might be just what you need. It's a brand new, direct replacement unit. It puts out 130 amps at 12 volts, spins clockwise (CW), and is what they call the 'Quiet Version' (less whine, which is nice). It's got a 3G series case, an internally regulated (IR) setup with a MOSFET field transistor for reliability, and an internal fan (IF). The plug code is 330, and it comes with an S8 class pulley (59mm diameter). The case is 148mm across. This thing is built to replace a ton of part numbers – we're talking XL1U-BB, XL1U-BC, XL1U-BD, XU2U-AA, 334-2510, AFD0084, 40014073, and many more (check the full list to match yours!). It's designed for those big SUVs from around 1999 onwards. The rectifier inside uses sturdy 13mm press-fit diodes. Just a heads up, mounting hardware isn't included, and it's made in China. But if your old alternator gave up, this is a solid, spec-matched option to get your voltage back where it should be and keep all your electronics happy.
