Here we have a good used hydraulic sway bar pump assembly removed from a 2013 ml63 with only 63,000 miles. It should fit many 166 chassis ML/GLE trucks from about 12-19 with the same active sway bar option. I also have many other parts from the same vehicle available, just ask if you need something. Please confirm fitment with part number BEFORE buying if you have any doubts. Removed from, Vin# 4JGDA7EB7DA240997
