Thanks to everyone that has chimed in their $0.02. I appreciate the input.
friendly_jacek, no need to be sorry for correcting my mistake! If I was working with my Pop on his Custom '55 Chevy and I was wrong I might be cross, but not when referring to my 2 year old Japanese designed Trucklet with 4WD. I know the limits of my knowledge which is exactly why this forum rocks!
So for all that have been following this string here's the update:
I picked up my 2010 Rav4 V6 from the "Stealership" on Thursday afternoon and was told that the leak was all fixed up. When I pressed as to what else my have been damaged due to driving after the leak appeared I was told "don't worry, you'll be just fine".... Yeah, right........
So after reading the replies you have all offered (Thank You!), I decided to review the invoice I got from the dealer and crawl under my Rav4 to check things out. Boy am I glad I did.
As a quick refresher, I noticed oil under the engine bay just off center and slightly behind the front passenger axle. Years of dealing with stealerships and home contractors has taught me to take pictures so here is what I found Tuesday morning. The brown marks you see are from my front tires.

I told the dealership exactly where I saw the oil when I dropped it off for an oil change and tire rotation. When they looked into my concern I was told by the rep that it was my Rav4 that was leaking and that it was in fact the front passenger side axle where it connected to the "electromagnetic coupling assembly". Again, thank you friendly_jacek for setting me straight on this. I was told they would replace this part under warranty and I would be good to go.
After I went back later in the day to pick up my Rav4 I compared the invoice they gave me with what I saw under my Rav4.
Here's a pic of the invoice that clearly shows that they replaced the Rear Electromagnetic Assembly with a Form In Place Gasket (F.I.P.G) and not anything in the front end related to axles or transmissions/transfer-case.:
So I start thinking, what the heck! I clearly told them the leak was in the front end and they then told me the leak was related to a front axle. Now I see this invoice showing work on the rear... Here's what I found when I crawled under my Rav4 after I got it home.
Shiny new coupling assembly bolted to the rear diff pick 1:
Here's a 2nd pic of the new coupling assembly where you can see the red F.I.P.G. leaking out between the assembly and the diff:
When I took a look at the front end I noticed that not a single bolt appeared to have been removed from any of the suspension or the plastic shroud. Here's a pic of what I found under the passenger side front end when I got it back:
So suffice it to say I immediately called the dealership back and talked to the rep that had been helping me. I explained the whole situation about how I had told them about a leak in the front end, was told they found a leak in the front end, then saw the only work done had been to the back end. The rep replied, "well, I might have been incorrect when I initially told you they found the leak in the front axle". This just goes to show that the service reps are Salesmen, not mechanics. Either way I demanded they re-book me a time asap to take a 2nd look at it.
I'm beyond annoyed that I now have to take it back a second time. I have avoided driving it because it's obvious that something spilled it's guts in the front end and I am very afraid of damaging the tranny or associated parts by driving it further. I'm going to demand that the Tech/Mechanic bring me back while its up on the lift and show me what they find/think the issue is.
So... Other then then typical dealership ineptitude, what do you guys think. Given where the oil marks are on the driveway, what do you think may have "given up the ghost"? I would love to go into the dealership on Tuesday morning as prepared and knowledgeable as possible.
Thanks again for all the help!
