Rear motor replacement pic

No Lightning's listed. Fusion PHEV & Mach-E, listed, but NO Lightnings

Old thread on service manuals:
https://www.f150lightningforum.com/forum/threads/f-150-lightning-service-manual.16514/

I think the Lightning is under F-150 with all the ICE models.

This was discussed extensively in the previous thread and on the website. The modern factory manuals are taylor made. You enter the VIN and you get a taylor made manual.

So YES the Lightning is available on the factory-manuals.com website, that’s where I bought mine.

The fluid in the differential/final drive is going to age less than the diff/axle in a conventional vehicle. With an active pump and filter, its going to stay clean for a long, long time. With clean fluid, the gears and bearings are going to last nearly forever as well.

My prediction is that the seals or the pump will generally be the first things to fail.

I agree with the poster who mentioned that if you ever do swap the oil, it will; be way less work to just suck it out with an extractor from the fill hole and the port where the filter connects.

Well, just spoke with service advisor and its looking good.
He says they have been test driving it and 1 pedal works and codes are gone.

Cautiously optimistic for now.

I'll post the codes and info when I get it.

Thought I’d post a pic of rear motor out of the truck. I couldn’t find any posts of this having been done before.
Rear motor is being replaced in attempt to fix my 1 pedal drive fault.

Apparently the module in question doesn’t come separate and the entire assembly gets replaced.

Question, what does that filter do?
Seems like creating an awful lot of junk for the price of a module.

Collects metallic fragments generated by the differential gears.

Thank you, at what point do we need to replace the filter and add more oil or fluid?

It's never stated in the owners manual or service guide, but I'm planning to request the technician change it at 150K

Well, truck is not fixed.
Rear motor replacement did nothing but waste a reportedly 8k part.
Codes are back and 1 pedal is still non-op.
I’m at my wits end with this thing.

Bummer. This is the problem with issues of this nature. Newer tech, poor training and techs that are less than worthy. Most techs these days are flat rate and just not willing to invest diagnostic time that they probably won't get paid for. So they blame the most expensive component and become parts replacers which results in this unfortunate situation more often than not.

I bought an ostensibly factory service manual from https://www.factory-manuals.com/

I was a little dubious at first, but after reading through parts of it, I think it is legit. I have used it for a couple of things already. It was about $130. I am a hands-on engineer type and I really like having a manual.

Wow, sorry. I assume you took it to Lewiston? They too must be frustrated. I just reviewed your previous posts, sure seems to be a software issue, perhaps after that update.

Perhaps a dealer in the Tri-Cities?

I just lightly scanned this thread, but I'm assuming they tried a software reinstall or fix? I would think there would be a sensor somewhere too which I'm sure they checked.
