Replaced: Rear Driver DRIVE AXLE... under warranty @ 49,000 miles

[hturnerfamily]

I mentioned a caking/leaking of grease around the driver's rear axle, on the tire end, the other day at my 50,000 mile checkup...

they replaced the whole Drive Axle assembly today, in about 3 hours, although I heard a lot of 'banging and hammering'
during the process... I was told that it's not only because of the huge casting assembly that handles the suspension, but
the huge amount of 'loading' on the rear drive/motor setup, that makes this more difficult than normal. I can imagine.

Replaced under warranty. $0. Had no prior issues during driving, though. Had no issues after replacement while driving home.

BEFORE:

tire side axle boot, caked grease all around

probably a leaky outside axle boot

the interior 'motor end' boot looked just fine

new Drive Axle... notice the 'no-rust' interior connector

looks like I've got some additional 'cleaning up' to do.... oh well.

Thank you FORD.

I think that's what they replaced on mine at my 10k mile service. They said it must have just been defective from the factory cause it was leaking a little bit, but it was nice to have it quickly taken care of. They even picked up my truck and brought it back afterwards!

Great to see Ford replaced this. Is that typical for a leaky boot? I guess it may have compromised the gear teeth perhaps? Note: not a mechanic lol.

On my 2022 with 20,000 miles was just replace last week. It was noticed when I was having the tires rotated. Ford covered it at 100%.

Good to see things like this posted, one more thing for me to keep an eye on and be able to catch early if so.

Do you have extended warranty?

Should be factory Powertrain warranty.

I have to go for my 20k checkup. I'm seeing a slight weeping below both outer hubs. Going to ask them if that's normal.

at first, just seeing a dry build up of 'grease' on the lower control arm casting was not a big red flag... at least, until I went and looked at the other side and it looked like it was just shipped from the factory: clean.

the boots are to not only CONTAIN the grease for the moving parts within, but also to DETER any infiltration of dust, dirt, and debris into that same moving part. They really can't be 'replaced' since they are BUILT as a whole single unit, onto the axle... and, as some might do, trying to make use of a 'split boot' replacement would be risky...
