Was looking underneath my Bronco after a full day of highway driving when I noticed the transmission crossbar frame looked "wet." I crawled under there and found a gray, viscous fluid (see pics) coating the cross frame bar which is possibly coming from the end of my front driveshaft where the bellow appears to have come apart (or torn or separated).

Not sure how long it's been like this because the fluid isn't leaking onto the floor of my garage. It's either a very small leak or all the fluid leaked out earlier on the long trip.

No warning lights and no apparent issue with the way it steers/drives. Have it going to the dealer this week but they're so swamped, I doubt I'll hear anything about my Bronco for another 10-14 days. Anyone else have this issue or know what might be going on?

The boot spilt or came loose & is spitting grease. Take it in for warranty to address.
Interesting, you thinking it's just grease? That'd be good news. Will let you know what the dealer says. Thanks, man.

Yep, just grease. No immediate issue, long term running 4-wheel drive will cause wear.

The bellows is covering a slide spine system that allows the length of the shaft to adjust as the suspension moves through its range. They greased it rather than using an end seal, likely to ensure the grease doesn't go away if you go through high water.

Yup, this was the case. And since Ford doesn't supply the bellow as a separate part, they ended up replacing the entire driveshaft assembly. All covered by warranty.

Yeah I drove my bronco all day and night yesterday parked it about 3 am, everything was good.
I went out this afternoon and I saw the reddish fluid underneath my bronco.

I crawled underneath and it seemed to be coming from where the yellow drain plug to the tranny is but I have a bash plate underneath my truck and everything's dry extend my hand on top of the the plate and I touched around the screw the yellow plug and it's all dry but I did notice some slight Gray underneath the stabilizer bar and on the plate.
I'm going to have to go and check the boots I do notice that there's a space between two metal pieces and one sides rusted and the other side seems to be normal but there's at least a quarter inch gap on 1/8 of an inch cap so I think it's one of the axles but it's on both sides like that.
