I am having an oil leak on the ouside of the passengers side rear end out by the tire. As I am not very familiar with indepedent rear suspension I wonder if anyone can give me any advise on what it is & how to fix it. I tried a search but didn't find any answer. I looked a behind the rear wheel but I saw nothing. I get a few drops on the driveway but not all the time. The boot for the CV joint looks OK no tears.
