The filter is an insert. Do yourself a huge, HUGE favor and get a device called a Topsider. The ML makes a god-awful mess when you drain the oil from the pan. It will soak the front tire and a lot of the suspension, your floor, your clothing and irritate you to new levels or ire. You have been warned......
