Hey everyone. I was wondering if I need to change my diff oil in my wrangler X. It only has 30,000 miles on it, but its a 2002 so its 10 years old. I have never checked it but have gone in some pretty deep water with it. Do I NEED to take the cover off and reglue it, or can I just pump it out? My dad says to pump it because his leaked after he took cover off, but that was 15 years ago. Thanks!
