1928 Wheel Bearing Locknut Socket. This is a 3/4" square drive, 6-point socket designed for removing or installing wheel bearing locknuts. It fits 2-9/16" rounded corner Dana axle nuts found on Ford light-duty truck axles. The socket is made of high-strength steel to resist rounding out under high torque loads. It is designed for use with manual tools only, and using an impact tool will void the warranty.
