Should I Be Concerned (leak?)

So tonight as I walked out to the truck after dinner I noticed this spot on the drivers side frame. It’s at about the mid point of the truck and I’m not sure what could be causing it. I looked at the other side and didn’t see anything. After I noticed some other areas in the front wheel wells (driver/passenger). I popped the hood and didn’t notice anything that would lead me to believe I had a leak. Does anyone have any idea? I just hit 20k and need to take it in for the service but thought this was odd.

 

Very strange. If you drove over some oil puddles, it should leave a splash pattern. Is underneath of your engine dry?

 

Yep, didn’t notice anything like this in any other areas.

 

Hmm mine looks about the same. I always just thought it might of been grease or oil from oil change.

 

Check your cv boot maybe

 

Busted boot sprays grease all over the wheel well

 

Same on mine, 22,000mi, doesn’t leak enough to drip on the ground. Smells petroleum ish.

 

Well I’m glad I’m not the only one that has this I guess lol.

 

I have the same problem. Dealer says it’s from the AC. Im still trying to pinpoint it.

 

That doesn’t sound right. The only thing that should be leaking from the ac is water. I extended my ac drip line to not drip on the frame.

 

probably oil change spillage

 

mine is on both sides, same area on the frame both sides. I am dropping the truck off for the recall on one of the cameras on Thursday so I am going to make a point to have them look at it.

 

Maybe the 3rd Gens have self lubricating frames to prevent rust?

I have these on mine but grease is coming from aftermarket UCA's as it eventually squeezes the grease out of the bushings.

 

Check your break fluid.

 

Thank you for all the responses, when I go in for 20k. I’m curious as to what they tell you Edgerat, please let me know.

 

I got the same issue going on here.

 

Dealer can't find where it would be coming from, they did acknowledge that it is weird that there would be that kind of residue in matching areas on both sides of the truck. Once I get it back I will clean it up and do a better job keeping track of it. They checked steering, brakes, and all systems in or near the area.

 

They said the same thing to me. I’m going to wrap a white shop towel around the areas and see what I come up with.

 

Shock Oil?

 

If it were on the passenger side, I would say check the A/C drain. Have you tried the sniff check?
