Review on 🔌 DB Electrical 400-14111 Alternator for Ford Expedition V8 4.6L 5.4L 2003 2004, Lincoln Navigator 2003 2004 - Compatible with/Replacement - 135 Amp - Part Numbers: 3L74-10300-AA 3L74-10300-BA 3L74-10300-BB 3L74-10346-AA by Mike Newbill

That was the last piece of my puzzle. My Expedition is a pristine 2003 Eddie Bauer with a TV/DVD combo. I haven't driven a truck in months since replacing the timing chain, water pump and coils. My old alternator was buzzing/whining so much I thought something else was wrong. I didn't know the old one was bad until I drove it and found the battery wasn't charging. Long story short I ordered and installed this and have already driven 400 miles with no problems. The quality of the part appears to be top notch, as does its performance.
