Approximately 20 minutes after Aircraft X departed; the Ramp Supervisor brought a part to Maintenance Lead Tech and stated they found on ground at gate in the area around nose of aircraft. After seeing the part I called Maintenance Control. I informed him that I had changed the left nose tire and wheel assembly earlier that night and that this part could possibly be from that work. [I] asked him to stop the aircraft when it lands in ZZZ1. [I] looked up part number and gave to him in case needed. All work was performed per maintenance manual. Waiting to hear outcome of inspection in ZZZ1. If part that was found here in ZZZ is indeed missing. Bushing/support is a very loose fit inside the nose wheel axle may need to pin or some sort of way to prevent it from falling out or getting stuck inside of axle nut socket with grease.
Maintenance Technician reported that an A320 part was found in the area where maintenance had replaced the nose wheel.
