A method for manufacturing a wheel bearing apparatus comprising an outer member integrally formed on its outer circumference with a body mounting flange to be mounted on a vehicle body and on its inner circumference with double row outer raceway surfaces (2a, 2a); an inner member including a hub wheel and an inner ring, the hub wheel being integrally formed on its one end with a wheel mounting flange and on its outer circumference with an inner raceway surface corresponding to one of the double row outer raceway surfaces (2a, 2a) and having a cylindrical portion axially extending from the inner raceway surface through a shoulder, the inner ring being press-fitted onto the cylindrical portion of the hub wheel via a predetermined interference (δ); and double row rolling elements (3, 3) contained rollably via cages between the inner raceway surfaces (4a, 5a) of the inner member and the outer raceway surfaces (2a, 2a) of the outer member characterized in that the wheel bearing apparatus is manufactured through steps of: measuring a distance Ho from a contacting point between one outer raceway surface of the double row outer raceway surfaces (2a, 2a) of the outer member and one rolling element of the double row rolling elements (3, 3) to a contacting point between the other outer raceway surface of the double row outer raceway surfaces (2a, 2a) of the outer member and the other rolling element of the double row rolling elements (3, 3), a distance Hi from a contacting point between the rolling element and the inner raceway surface of the inner ring to a smaller end face of the inner ring, and a distance Hh from a contacting point between the rolling element and the inner raceway surface of the hub wheel to a shoulder of the hub wheel, wherein the distance Ho, the distance Hi, and the distance Hh are measured under a condition in which the outer member, the inner ring, and the hub wheel are rotated, respectively, and wherein the distance Ho, the distance Hi, and the distance Hh are measured with use of measuring jigs (11, 16, 19) comprising simulated members of simulated rolling elements, a simulated outer member, a simulated inner ring, and a simulated hub wheel; comparing a difference Δ H = (Hi + Hh - Ho) with a reference value of a model article, and selecting rolling elements each having an optimum diameter for correcting the difference Δ H between the measured values and the reference values. measuring a distance Ho from a contacting point between one outer raceway surface of the double row outer raceway surfaces (2a, 2a) of the outer member and one rolling element of the double row rolling elements (3, 3) to a contacting point between the other outer raceway surface of the double row outer raceway surfaces (2a, 2a) of the outer member and the other rolling element of the double row rolling elements (3, 3), a distance Hi from a contacting point between the rolling element and the inner raceway surface of the inner ring to a smaller end face of the inner ring, and a distance Hh from a contacting point between the rolling element and the inner raceway surface of the hub wheel to a shoulder of the hub wheel, wherein the distance Ho, the distance Hi, and the distance Hh are measured under a condition in which the outer member, the inner ring, and the hub wheel are rotated, respectively, and wherein the distance Ho, the distance Hi, and the distance Hh are measured with use of measuring jigs (11, 16, 19) comprising simulated members of simulated rolling elements, a simulated outer member, a simulated inner ring, and a simulated hub wheel; comparing a difference Δ H = (Hi + Hh - Ho) with a reference value of a model article, and selecting rolling elements each having an optimum diameter for correcting the difference Δ H between the measured values and the reference values.
