The spinning issue occurs because the 1-1/2" female adapter has an outer diameter of 2-1/4", while the drive tool has a larger outer diameter of 2-1/2", causing them not to fit securely together. To resolve this size mismatch, you can use a reducer or adapter designed to connect components of these sizes. For example, the POWERTEC 70141 2-1/2-Inch to 2-1/4-Inch Reducer is a durable ABS plastic adapter commonly used to bridge this size difference. Alternatively, if these parts are part of a socket or drive tool system, consider using socket adapters such as the Titan 1/4, 3/8, 1/2 Inch Drive 2-1/2 To 2-3/4 Inch Socket Adapter Set to match the drive sizes. Always verify that any reducer or adapter chosen is compatible with your specific RV parts and intended use. If you believe you received the wrong drive tool, please review your order details for accuracy and contact customer support for a return or exchange.
