The hub mounting portion includes a number of flange holes adapted to receive a number of corresponding wheel studs. A number of drum pilots are positioned one each between the hub barrel and the hub mounting portion and are concentric with the hub barrel. The drum pilots are radially aligned with the flange holes so that each of the flange holes has a corresponding drum pilot. ## Claims ### Claim 1 A wheel hub comprising: a. a hub barrel; b. a hub mounting portion positioned concentrically around the hub barrel, said hub mounting portion including a plurality of flange holes adapted to receive a plurality of wheel studs; c. a plurality of individual drum pilots and combination wheel/drum pilots positioned between the hub barrel and the hub mounting portion and concentric with the hub barrel; and d. said plurality of individual drum pilots and combination wheel/drum pilots radially aligned with said plurality of flange holes so that each of said plurality of flange holes has a corresponding individual drum pilot or wheel/drum pilot. ### Claim 2 (depends on 1) The wheel hub of claim 1 wherein the plurality of individual drum pilots and combination wheel/drum pilots are positioned around the hub barrel in an alternating fashion. ### Claim 3 (depends on 1) The wheel hub of claim 1 wherein a size of each of the plurality of individual drum pilots and combination wheel/drum pilots minimizes load induced stress interactions between the individual drum pilots and the combination wheel/drum pilots. ### Claim 4 (depends on 3) The wheel hub of claim 3 wherein a size of each of the plurality of individual drum pilots and combination wheel/drum pilots minimizes the interaction between the pilots and the barrel of the hub. ### Claim 5 (depends on 4) The wheel hub of claim 4 wherein each of the plurality of individual drum pilots has a drum pilot contact surface defining an arc length in the range of 0.25 to 1.00 inches. ### Claim 6 (depends on 5) The wheel hub of claim 5 wherein each of the plurality of combination wheel/drum pilots has a wheel pilot contact surface and a drum pilot contact surface, each defining an arc length in the range of 0.25 to 1.00 inches. ### Claim 7 (depends on 1) The wheel hub of claim 1 wherein each of the plurality of individual drum pilots has a drum pilot contact surface defining an arc length in the range of 0.25 to 1.00 inches. ### Claim 8 (depends on 7) The wheel hub of claim 7 wherein each of the plurality of combination wheel/drum pilots has a wheel pilot contact surface and a drum pilot contact surface, each defining an arc length in the range of 0.25 to 1.00 inches. ### Claim 9 A wheel hub comprising: a. a hub barrel; b. a hub mounting portion positioned concentrically around the hub barrel, said hub mounting portion including a plurality of flange holes adapted to receive a plurality of wheel studs; c. a plurality of drum pilots positioned one each between the hub barrel and the hub mounting portion and concentric with the hub barrel; and d. said plurality of drum pilots radially aligned with said plurality of flange holes so that each of said plurality of flange holes has a corresponding drum pilot. ### Claim 10 (depends on 9) The wheel hub of claim 9 wherein the plurality of drum pilots includes individual drum pilots and combination wheel/drum pilots. ### Claim 11 (depends on 10) The wheel hub of claim 10 wherein the individual drum pilots and the combination wheel/drum pilots are positioned around the hub barrel in an alternating fashion. ### Claim 12 (depends on 11) The wheel hub of claim 11 wherein a size of each of the plurality of individual drum pilots and combination wheel/drum pilots minimizes load induced stress interactions between the individual drum pilots and the combination wheel/drum pilots. ### Claim 13 (depends on 12) The wheel hub of claim 12 wherein a size of each of the plurality of individual drum pilots and combination wheel/drum pilots minimizes the interaction between the pilots and the barrel of the hub. ### Claim 14 (depends on 13) The wheel hub of claim 13 wherein each of the plurality of individual drum pilots has a drum pilot contact surface defining an arc length in the range of 0.25 to 1.00 inches. ### Claim 15 (depends on 14) The wheel hub of claim 14 wherein each of the plurality of combination wheel/drum pilots has a wheel pilot contact surface and a drum pilot contact surface, each defining an arc length in the range of 0.25 to 1.00 inches. ### Claim 16 (depends on 9) The wheel hub of claim 9 wherein a size of each of the plurality of drum pilots minimizes load induced stress interactions between the plurality of drum pilots. ### Claim 17 (depends on 16) The wheel hub of claim 16 wherein each of the plurality of drum pilots has a drum pilot contact surface defining an arc length in the range of 0.25 to 1.00 inches. ### Claim 18 (depends on 16) The wheel hub of claim 16 wherein a size of each of the plurality of drum pilots minimizes the interaction between the pilots and the barrel of the hub. ### Claim 19 (depends on 17) The wheel hub of claim 17 wherein each of the plurality of drum pilots has a drum pilot contact surface defining an arc length in the range of 0.25 to 1.00 inches. ### Claim 20 (depends on 9) The wheel hub of claim 9 wherein each of the plurality of drum pilots has a drum pilot contact surface defining an arc length in the range of 0.25 to 1.00 inches.
