Default Differential leaking???

Had my clutch replaced last week and noticed some fluid coming from the drivers side of the diff. Its like a build up and dirt all sticking to it so not really sure where it coming from. Tech said he thinks its the axle boot on the drivers side as he thinks there is a small tear in it. I didnt see it so Im not sure. Also he said it has been slung on the top under the car above that boot.

You guys think it the axle boot or something else?

Car has 34k miles on it.

Clean the area very well. Drive the car and then while the area is still clean, try to see the source of the leak. Dye can also be helpful.

It could be the vent. It happened to mine after a long high speed (for me) trip in hot weather. It's the round nickle size cover on the drivers side. I cleaned mine off and in over two years it has not returned.

Follow the axle straight in. You can't miss it. It's on top of the first ridge.

Mine is also leaking after clutch change im PRAYING its just the overflow

But it "appears" to be coming from here


But that is the only spot i see it building up at so no idea i need to clean it to be sure.

Overflow from what? Is it kinda sprayed all over the underside of the car? Thats how mine is.

Anyone else think it might be the boot??

I have the same issue with mine. On the passenger side though. A shop noticed it when they had my car up on the hoist. Their thought was that it was the axle seal.

I have an aftermarket diff in my car. If it is the axle seal would the diff most likely be the culprit or the install of the diff?

Mine had the same problem.. Turned out to be the passenger side axle seal... Then when we were looking at it we found out that the transmission input shaft was leaking too... That added $700 to my first clutch swap. I had a hardened output shaft installed while having those two things done.
