To provide a preload inspection method of a wheel bearing device, capable of inspecting a preload with high reliability.SOLUTION: A preload inspection method includes: a press-fitting process S02 for press-fitting an inner ring; a first bearing preload value calculation process S03 for calculating a first bearing preload value on the basis of an axial negative clearance G1 between a raceway surface and a rolling element after the press-fitting process S02; an after-press-fitting rotational torque measurement process S05 for measuring the after-press-fitting rotational torque, after the press-fitting process; a caulking process S06 for caulking a small-diameter step portion to the inner ring after the after-press-fitting rotational torque measurement process; an after-caulking rotational torque measurement process S07 for measuring after-caulking rotational torque after the caulking process; a second bearing preload value calculation process S08 for calculating a second bearing preload value by adding a preload change amount determined from differential torque between the after-press-fitting rotational torque and the after-caulking rotational torque to the first bearing preload value by using a relationship between the rotational torque and the preload according to an atmospheric temperature; and a determination process S09 for determining propriety of the preload on the basis of whether the second bearing preload value is within a range of a reference value or not.SELECTED DRAWING: Figure 2
