Run it up on ramps or if you have access to a lift use it. Prepare to snake you arm up to the elbow to reach the end of the hose. I replaced mine (2) and the EGR tube (metal) and it takes patience. I finally destroyed the clamps and pried the hose pieces off as they were brittle to begin with. New hose, new clamps and some silicon spray to help ease it back on. The patience comes in with trying to get the clamps in place, but it can be done.
