This is the metal dust cover for the front wheel on the driver's side. It has the square hole for the speedometer drive cable. Aftermarket great quality. If your speedometer stops working or it is working strangely (jumping needle) check to see if the square hole or the speedometer drive that goes into the hole has been damaged. Sometimes the cap itself is damaged and will spin independent of the hub as well. Syncro Vanagon does not use this part. They don't have grease caps on the front hubs.
