This morning I moved my car and noticed a few drops of turquoise grease on the driveway. It seems to be up near the transmission, transfer case area? Could it also be axle grease?

 

Check all your CV boots on your axle shafts for tears, only spot in that area I would think of having grease.

 

Yeah, check those axle boot areas. What have you had recently done to the car?

 

I havent done anything to it except add some gauges.
Im not sure where its coming from and its that weird greenish-blue color. My assumption from previous cars is that the axle grease is black.

 

Isn't Redline that color?

 

Green grease isn't uncommon. We use it on bikes all the time.

Have you crawled under there and looked at it?

 

I have taken a look. But I cant determine the origin. Thats why I decided to post the color hoping that someone would be able to identify it.

From looking at the underside it seems to be on what looks like the transfercase. But I dont know if it leaking from higher up like from the axle or tansmission.

 

I'd just say keep an eye on it and if you see another glob, before you move the car, get under there and stare straight up at it.

It isn't uncommon for grease to just get globbed on when lubing the chassis, and then as parts wear and the car gets used, just have a glob fall off. Not to mention, if there was a glob somewhere, and it fell off, its not like the part is going to be unlubed. I would certainly check all of your axles and such to be sure they're lubed correctly, probably due the chassis lube check that goes along with a service and make sure its all greased up.

Other than that, if nothing looks torn up or ripped or popped, I can't imagine it being an issue.

Then again, there's no such thing as a qualified internet mechanic.

 

^ Yes - I'd imagine its gear oil myself too.

 

Gear oil is normally reddish... and it's also OIL. Which is a liquid, in case anyone in here forgot that little fact. Grease is a SOLID. Different states, kids.

If it came down by the t-case, and it's on the t-case, it's probably axle grease, and it's probably been slung all over by a hole in the boot. Get your hand up there and feel around for a tear in the boot. Or just keep driving on it until it starts clicking for a sure diagnosis.

Other thing to note is that marine grease is usually turquoise, and most people I know use that for suspension bushing lubrication. I don't think you'll find it to be the source, but you can check the sway bar bushings as well for the same color grease, though I'm not sure why you'd find it that far inboard.

 

Redline lightweight shockproof transmission fluid

 

 

So what is more common? A leaking seal or a cracked case?

Im leaning toward it being the transmission becasue it is hard to put into reverse in the mornings. It wont fully engage unless i come up off the clutch a little.

 

That sounds like a typical Evo clutch nothing to do with LEAKING FLUID . Rear main seals happen to leak sometimes. I have a bad leak near my oil cooler lines which appears to be somewhat common as well if you don't have a undertray

Are you sure it's grease or fluid. How about a picture?

 

It looks thick to me more like grease than an oil. Ill try to get a pic, its gonna be raining here the next 2 days.
