Yeah, then you are definitely leaking from the same place I am. Mine is the same, feels slimy, and most certainly doesn't smell like coolant. I think if it were coolant we would be smelling it hard once it heated up down there. Yours just looked green in that photo. So I am thinking diff fluid or engine oil. I'm gonna do the aforementioned cardboard trick tonight, that is, if I can get some jammed up ther in the right spot.
As far as my leak goes, it seems like its coming out when I drive, not like a typical leak that leaks all the time, driving or parked. I can go under there and wipe it off as much as I can with a rag, and then its still dry in the morning. But after I drive, its wet again...

Its actually pretty amassing that after almost 90k this is the first evidence of oil seepage. It’s kind of like finding you first gray hair.![]()
J, so you're saying its the seal around the diff? How can this be fixed?

PS - I hardly ever drive in water, its dry as a bone out here. The deepest water I have been in lately was this:
But then again, do you think just rain water splashing up that way would be enough to penetrate the seal?
I should probably know this already, but where is the condensor for the AC located? Since it's been warmer out lately, have you been running the AC? Maybe what you're seeing is just accumulated water dripping off the condensor, which is collecting grease and grime as it makes it's way over dirty engine and chassis surfaces on it's way to the ground? That would also explain why it only seems to happen when the vehicle is driven.
Y33 not a bad idea.
Bart, I would at least change your diff fluid no matter at if it has been 30k. I think the intervals is 15K. But I could be wrong and probably am. The seal is about $14 but a pain in the arse to get to. Our axel is set up to only be serviced by taking it off the brackets and dropping. I have had this leak for quite some time, maybe a year now. Everytime I have either added oil or changed it stopped. Changing this seal out is going to be one heft mech ticket, the estimate is 4hours of labor and this is why I have not done it yet. In the meantime I did manage to build some drop brackets so we can tackle that at the same time. I am not 100% sold on it being the seal but I kind of think it is. The spray pattern seems to be from circular motion while in drive.
If we go thru the trouble of dropping the diff we mite as well do the CV boots too,
get it all with one shot. My leek is very slow so I can wait. I know my CV boots are next so if it is the seals I can wait.
