What would be leaking?

My 2014 Overland has been in the garage for the last several months attached to a battery tender while I've been enjoying the top down fun in the MX5. When I was in the garage the other day, I noticed what appeared to be an oily stain just behind the left rear wheel. It appears to be colorless and does have an oily consistency. I am currently undergoing treatment for a back problem and I can't get down to crawl underneath the vehicle to see what's going on. The stain appears to be fairly large, maybe a foot wide and two feet long running from about the middle of the rear wheel back to the bumper and on the inside of where the tire sits on the floor. I plan to call on Monday to make an appointment to have this checked out, but I was wondering if anyone had any ideas as to what the problem might be.

Thanks.

Re: What would be leaking?

My first thought is brake fluid. Check the level in the reservoir before driving.

That's what I fear as well. I just can't think of anything else back there. Thanks.

Probably a rear shock failed.

Re: What would be leaking?

Do the air suspension shocks have that kind of fluid? Checked the brakes and they seem fine.

Called the dealer today - they can't get me in until the 8th. I'm probably going to be happy I got the lifetime service agreement.

Re: What would be leaking?

The rear are shocks and separate air spring, the fronts are strut incorporated with air spring (single unit).

Haven't sniffed shock fluid, but brake fluid has a fairly distinctive smell.
You could pull the top off the reservoir to see if it matches the leak.

That odor must be too subtle for my smeller to distinguish.

I'm not a wine connoisseur either.

the other two tests are:

...brake fluid when rubbed between fingers will be slippery like an oil but you will also feel a grippyness to it, whereas, oils are just pure slippery...brake fluid will also feel "thin" vs oils feeling "thicker" which is true as brake fluid is less viscous than most oils...try the suspect fluid between your fingers and then do same with know pure motor oil...the difference is pronounced.

...brake fluid is a great paint stripper....using a q-tip or cotton ball soak up some suspect fluid and "paint" it on a 1 in area of a painted object that you don't care about...the paint will cloud and then wrinkle as the brake fluid does it's work...it paint is not disturbed its not brake fluid.

Re: What would be leaking?

Unfortunately for these tests, this is an oily stain, not an oily puddle. Whatever leaking has been done was over a period of several months. I can get oily residue on my fingers sufficient to determine that it is oily, but there isn't enough there to really perform either of these tests. The size of the stain is substantial, but it is pretty dry.
