Didn't you say you found the brass fitting? Take a pic

 

 

And it says the two tanks are connected w a hose, how and where are the connected?

 

I actually don't have those plastic end pieces as I removed them. Not sure how you would reach the zerk with the end pieces on.

Anybody else?

 

I remove the bolts holding the right tank. That gives you just enough room for the grease gun. The tank just floats there. Better than taking the whole bumper off again.

Could someone show the tire carrier from both sides, and from the rear. Thinking about adding this to my AEV

 

Well I found the issue....the dealership did not install that part. I found it and installed. I have added grease now. About how much and how often?
