Oily substance dripping on mud flap Solved

[mep1811]

After about two hour of highway driving and four hours of off road driving we stopped for the night .
I noticed an oily substance dripping down the passenger side rear mud flap.
Seem to be like engine oil but have no idea. No smell.
By morning, there was no more dripping and no sign of any additional dripping.
Nothing in the wheel well.
Pictures attached.

Could it be related to the KDSS?
I don't have any warning lights.
Thanks

Two more pictures.
There has not been any dripping since that day.

Probably drove thru some oil. Get gas or go to an auto parts store? Think back.

I was driving the past four hours on dirt roads.

Something spilled in the rear 1/4 area? Shock reservoir mounted up there?

 

[mep1811]

I have simple OME shocks no reservoir.

Grease separating and dripping out of your jack, especially if hot lately?

 

[mep1811]

No evidence of anything leaking inside

The mud flap has fresh 'oil' tracks and what appear to be earlier tracks now covered in dust. If you backtrack the fresh 'oil' upwards where does it lead?

Any chance that it's fuel coming out of the filler area, aren't there some relief valves there?

I had the breather system serviced and cleaned by Overland Cruisers no leaks.
the liquid substance does not smell like gas.

The rear AC condensate drains back there somewhere.

Jack is purely mechanical, no grease or oil other than residual to lubricate.

Driver's side.

This was an oily substance. I don't run the rear a/c .

Following. Are there any KDSS fittings or lines that route above this area? Very weird.

@mep1811 you really use your 200 for its intended purpose. The dust should make tracking down the source fairly easy if you can climb under the truck at night with a headlamp and flashlight.

Rust-prevention goo dripping downward out of a body drain somewhere? I seem to remember the rear sunroof drains terminating behind the rear wheel wells.

Nothing KDSS related in that area.

No rain. No recent rust prevention. The truck is a 2013 that I've had for 16 months.
I've put about 26K on it so far.

This is where I was when I noticed the dripping. Deep in Helena National Forest.

There are different pieces of metal that look like they have to be removed.
I haven't cleaned anything so it should show up when opened up.

Rear wheel seal? Is there oil on the inside of your tire getting thrown into the fender and leaking down the mudflap?
