Drive shaft / propeller shaft flange nut for all Mercedes-Benz G-Class trucks.
Early type drive shafts use 6 nuts per flange and later type drive shafts use 8 nutss per flange.
Don't forget to purchase new bolts too!
These little guys are easy to round off in those tight spaces, so make sure you always have a few spares on hand.
Original Mercedes-Benz part.
