now... a leak at the transfer case.

this truck has been leaking everything from everywhere since last fall.

started with the coolant bypass pipe, then the oil pan, then the oil pressure switch, then i burst a line to the clutch slave.

so i replaced the coolant bypass pipe, patched the pan with a sheet metal skrew and jb, cleaned the crud off the engine to find the ops leak, and then burst the line on my way home from the grocery store yesterday. i replaced slave, master, and lines. now none of that stuff is leaking, and I got a bunch of fresh fluid in the truck as a bonus. I can't flush the brakes until i go ahead and replace rear drums, bleeders are siezed and it should be done sometime soon anyway.

i figured i'd go ahead and swap the trans/transfer/diff fluids and be done (for now) but no... i got the transmission fluid swapped out, then moved on to the transfer case and saw this:



i hope you can see the picture. if not, oil is sprayed all over and seems to be coming from a black box attatched to the transfer case, on the back side by the fill and drain. i don't know the name of this part, or if it is a common thing to fail/easy enough to fix?

i am learning on my own as i go, and the victorious feeling i get from fixing stuff is dwindling. and i'm worried about what i'll do when something big breaks.

 

Hard to tell but it might just be grease from the u-joint flinging out as the driveshaft spins.

Gear oil from inside the t-case would be more drippy like engine oil

 

I can see the picture, but I’m only seeing grease from the driveshaft U-joint as well, which is normal when they are greased regularly / correctly.

 

well that's nice to hear, i'll clean it up and just keep an eye for puddles.

 

but... i haven't greased the driveshaft since i bought the truck 2 years ago. i guess i should do that.

 

100% from the u-joint. Nothing to be concerned about.

 

alright. i'll quit being concerned.

thanks for being here guys, gotten alot of help from other peoples experience on this website.

 

Give it a smell. No mistaking gear oil from grease.

 

It looks like you have greaseable u-joints so I'd grease them. I have the same marks on mine and I grease my u-joints at the 5000 mile oil change.

 

Yep, U-joint grease. Nothing to worry about.
I have the same stripes under my truck and am confident that is one area of my truck that will never rust.
