I noticed a spot in my garage a few weeks ago and thought it was potentially my oil pan (2018 plastic pan), but the oil appears to be coming from my differential. I haven't had time to dig into the issue deeper (baby due any day now). Does the 2015 - 2020 F150 have a front differential vent tube? If so, I am wondering if it has come loose or if it leaked fluid due to heat build-up after extend use.

It's under warranty, so I'll let Ford deal with it, but if like past experiences, this will require multiple trips to the dealer.

 

They do have a vent tube, it is located underhood by brake master cylinder, has a white plastic cap on it.

 

Thank you. All I've found when searching the forum is for 2004-2008. I presume this is because the front axles, aside from IWE's, aren't problematic.

 

I had the pinion seal changed on my truck's front diff because it was leaking. Actually, the dealership did the work without me even asking. I had taken the truck in for an oil change. They noticed it and fixed it on warranty. I have a good dealership.

 

It should be fairly obvious if its diff fluid by the awful smell of it. I recently has a CV axle replaced under warranty and the dealer ripped the axle seal putting the new one in and on the 45 mile trip from the dealer to home is leaked bad and covered the entire underside of my truck with gear oil, dont wait until its that bad because it stunk for months.
