Who has the highest mileage 5th Gen 4Runner here?!

Before and after I cleaned it up to confirm the source of leak after driving it around. Look closely on the left side of the plastic plug to the bell housing and you can see a drip. It is not spotting on the driveway, but it’s dripping onto the rear skid plate where it blows off at highway speed. Can see a plume of oil back on the fuel tank skid plate cover.

P.S. don’t know why the second pic is getting flipped upside down. Tried twice with the same result.

Darn. Hope the Blue Devil product works. I have heard AT-205 works sometimes, depending on the leak. I assume you have to continue to put this in the oil to keep the rubber plump?

From what I’ve read, all the liquid rear main seal treatments use the same chemical. Mixed reviews with some saying it did not work, but most saying it did. Says it’s a one time treatment, but saw at least one poster who said they use it every oil change.

Worth a shot. Be interested to see if it works.
 
306K and some change. Just replaced universal joints on rear shaft. They fought like hell to stay in there but a lot of heat persuaded them to give up.
