What fluid leak is this?

For a while I assumed it was my wife always dripping her Starbucks when she parks here however I left my car for a while here and saw some fresh drops and now I know it's the 4runner. It's a 2019 TRD pro. Just finished the factory 35k check/maint. Don't mind the leaf, I just used it to check tackiness. It's coming from passenger side engine bay

 

Sure it's not pudding? jk Best guess from 30K feet is white lithium grease. If there's that much on the drive you shouldn't have to look to hard under the truck to spot the source.

 

Gravy?

 

I agree with moon landing. It looks like white lithium grease most of the spots.
The darker shade with the leaf in it almost looks like a different product or just “fresher”?

I used to spray my Explorer rubber cv joint I think we’re called with white Grease once per year. My mechanic showed me how. He just showed me where to spray the part as it squeaked. Maybe something similar on the 4R

 

Is someone secretly spraying your underbody with wool wax or fluid film? Looks a whole lot alike like that. Only one way to make sure. Taste test.

Edit: I jest! You could just smell it. If it smells like wet sheep, it’s Fluid Film. If it smells like a dry sheep after a bracing jaunt in the field, then it’s Wool Wax.

 

Chick-Fil-A sauce?

On the real I'm really curious as well what this is.

 

good call it sort of does look like fluid film, especially if it was the kind of non aerosol can.

 

LCA boot leak? Outer tie rod end boot leak? I had a cut on one of my outer tie rod boots and looks very similar.

 

That looks like your CV boot is toast. As someone stated, very easy to spot.

 

CV boot is compromised, likely due to weak bands. Once contaminated with moisture CV grease will turn in that milk shake. Don't ask how I know. Remove Large band, clean the best you can, repack with CV grease (Redline makes good stuff), Put new band on and you are done. Don't ask dealer to fix it because they will try to sell you new axle or will say new boots required which after labor about same as new axle price wise.

 

Check front diff also but that fluid is usually brownish
