Had an issue with my Front Diff

[Moose Whisper]

Have a 2020 Ford 150 and was backing up to my trailer in 4wl and then I heard a loud bang. Truck was on ice/snow packed ground. What are your thoughts.

Seems reverse in 4l could be breaking things

 

[WhiteLightningnshitshadow]

in a 2020?

Grenadine front diffs are common.

I just had to reverse my 2022 f150 up a snowy hill and definitely was thinking about the potential for grenading.

Reverse in 4L is the shortest gearing and thus the most torque that the 10R80 can make. It's basically a stress test on the whole drive train. I would go so far as to say that we should all probably put our trucks into 4L and reverse before the powertrain warranty expires in order to have at least a hope that we got one of the good front pumpkins.

Wish I'd read this 45 days ago....

Although, I do have the extended ESP with like $50 or $100 deductible....Am I safe to give it a go?

OUCH!!!!!

God damn I gotta try this before next year and see if I can make it explode before warranty expires. Not sure if tremors fronts are different, scary.

4l in and good traction soil puts alot of tq on the assembly in reverse
when i use 4l moving the trailer , i select the slippery mode as it softens the throttle response
its easy to give a ton of throttle in 4l and not know it
but in any GO... the differential should be up to spec to handle the loads,
everytime i see the failures its complete OMG fail

most of time 4h works plenty
in my situation

and i use my front hitch almost all the time if i have to move the trailer to its parking spot

Only if you want to visit the dealer and lose your truck for however long it takes for them to repair it...

To be fair, despite all of the reports I still think that this failure is pretty rare AND way too common at the same time, if that makes sense.

Damn so this happens on 13th gens too? Maybe time for Ford to go to a steel front pumpkin. My dads F-250 is the same material front and back which is not aluminum like the F-150.

Every case of this I've seen posted is putting truck into reverse with 4L or 4H. Something I do in winter snow to back up my uphill driveway when needed. I'm definitely curious about these threads.

Does the truck have a lift or level kit?

No lift

Torsen added by any chance?

I do the exact same thing. My shop is on a hill and most times I end up reversing in 4H up the hill. It’s either that or a 3 point turn in snow/ice which just make a mess in my driveway
