Thanks grossgary, I had a look tonight and it is definitely the right seal leaking onto the exhaust. The CV boots are fine. Couple other questions while I'm drinking at the fountain of knowledge
To remove the CV shaft from the stub, do I have to take apart the wheel/hub assembly or would there be enough slack in the shaft to slip it off?
While I was under there, I noticed that there's two drain plugs, one in the transmission pan and another forward of that under the CV shafts. Are they two different reservoirs or are they just there so that you can more effectively empty the tranny when you do an oil change?
