New issue: front gear differential seal leak

[AP87]

Still at the dealer but told I have a “pretty bad” front dif leak. 19k miles on 2.3.

2023 2.7 Badlands with ~20K miles. Dealer changed my oil and then I noticed a small leak a few days later. I assumed it was spillage or something else related, turned out to be front diff pinion seal. Worries me a bit bc the only time I’d get visible spots under the bronco was when I parked on an incline…guess I’ll have to purposely park that way to check it frequently in the future.

I've had the front pinion seal replaced twice before the front differential had to be replaced, and the bearings and rollers replaced for the rear differential. Rotated the tires yesterday and found the front pinion seal is leaking again as well as both rear axle seals. Still months away from the 2 year anniversary of its arrival... seems these might be ongoing issues and have no idea what I'll do when the warranty runs out.

Oh man. When I had my pinion seal replaced, I got under afterwards and saw some oil along the top of the diff. I don't know if they didn't clean it off or if it's leaking again (!), but when I fix my engine skid I'll clean it so I can monitor it.
