I can\u2019t make out the sound but once upgraded the alternator on my 29 roadster pu that had a late model bronco v6 in it and the darn thing sounded like I had a super charger with the whirling. Crazy sound but ran perfectly fine for as long as I had the truck (years).
First gen Expedition- I'm not a Ford fan, but some of those old Expeditions were amazing. Definitely seem to be hit or miss, either bulletproof or a nightmare with no in between. My father had a 98 that he bought new and scrapped in 2019 with just shy of 500k miles, absolutely beat the living shit out of that truck and it just wouldn’t die, only ever needed an alternator, 2 shifter cables, a brake hose and 2 ignition coils.
Fords can be really picky about which alternator you use! Even if it’s a remanufactured Motorcraft, it’s worth it. Had a friend with an 11 Edge 3.5 that we put a aftermarket alternator in and it complained errors etc… for months till we finally swapped it out and it worked fine with the Ford part!
2021 Got the extended warranty, one year after the standard warranty went, so did my alternator. Extended warranty covered it.
I just replaced mine with a motorcraft one from rock auto. Yeah it's pricier than reman or other brands but if it lasted 20 years and 190k, I figured that this would last just as long. Get what you pay for
I also noticed that the alternator looks like a remanufactured unit. I’ve been reading about how these PCMs really don’t like reman units that are not built perfectly to spec. It’s best practice to replace these with only motorcraft units.
Been there with a Motorcraft alt. 181K miles. She stopped charging. No batter light on the dash. I laid it to rest and paid my respects.
I've got a 2017 ford escape needs a new alternator costs 1100 $, wtf for a Ford not happy.
I’ve been busting my butt all day trying to get the alternator out of my 2004 ford focus (mk1) for a few painful reasons
My neighbor had a Ford mustang and he had to jump start it about once a week. I checked the alternator and it had power when the car was off. Bad diode.
