I have a 2012 odyssey and while I was changing the oil I realized the passenger side cv axle is leaking at the transmission, how difficult is that seal to replace? I haven’t really found a whole lot of info about it.

 

Pull the axle and pop the seal out and replace.

 

welcome to the forum. If you plan to do this work, you may want to obtain a ody service manual. It will instruct you better if you are unable to find a utube video on R&R of the axle seal. Also will help to save a lot of money doing diy repairs on your ody. I get most of my older service manuals from Ebay. or auto parts house
