Some kind of weird clear oily liquid leak.

I have a 2013 5.0 and it stays in the garage and I noticed today about the size of a quarter on the garage floor when I pulled it out to wash it there was some sort of clear oily liquid at a spot to what I thought was directly below the rear end/axle. I looked under the car and couldnt see any leaks or oily spots on the axle.

What could it be? it has no color, its clear and no odor?

An Ideas?

It could be oil from your shocks.

But its like right in the center below the rear axle, could be be running from a shock and then dripping in that spot?, seems like it would have to do alot of traveling to just end up in that spot and the rear shocks dont appear to be leaking either....Im dumbfounded.

I have a 2012 5.0 and when I was replacing exhaust I noticed the rear axle had oil on it behind the rear driver side wheel. Seemed like it was coming from rear axle breather. I believe it may be normal but could be wrong. Was not leaking on floor but just may be what you are seeing.

I may have to take it to the dealer (which I hate) and let them see what the problem may be but if they try and keep it overnight, I will take my tent and sleepover I would never leave my Mustang overnight at a dealer with a bunch of mechanics....

Well let us know what they say. Wonder if others may also be experiencing.

Been there, done that. Ended up with a cracked radiator cover and no fix to the original problem.

Sounds like the breather for the rear diff.

You could take it to a quick oil change place and ask nicely to run it over their pit and have a look, if you don't have a jack and jackstands.

I'd look carefully at the differential (esp if spot was centered)

Brake fluid is clear, and there should be a brake line "splitter" (a "T") to each end of the rear axle. The brake line from the master cylinder would run along the drivers side, to the rear axle, almost center, then split off to each rear caliper.

Clear oil is brake fluid. Never heard of red brake fluid as you mentioned ("...the tank with my brake fluid is full and is the color red"). Hope someone who did some maintenance work on your Mustang did not top it off with the wrong fluid. Red or orange looking fluid is automatic transmission fluid; at least in my 2011 Mustang.

I checked my brake fluid today and it feels and looks the same as whats on the garage floor however looking at the brake fluid from outside of its container its looks reddish brownish but when I stuck my finger in the opening it comes out clear, anyway making a appt with the dealer to get it fixed even though i went underneath the car in the back and didnt see any leaks whatsoever...

Could be the diff breather. I just took mine in 2 weeks ago for it.

I thought that too, but that oil is a darker, thicker oil, with a "heavy pungent" type smell. The OP stated it was a clear oil which lead me towards brake fluid.
