Claim:
A method, comprising: selecting an outer shell component, an intermediate component, and a bearing component from a kit that includes: a plurality of outer shell components, each of at least two of the plurality of outer shell components having (i) an outer diameter that is distinct in size in relation to the outer diameter of the other of the at least two of the plurality of outer shell components, and (ii) an inner diameter that is distinct in size in relation to the inner diameter of the other of the at least two of the plurality of outer shell components; a plurality of intermediate components, each of at least two of the plurality of intermediate components having (i) an outer diameter that is distinct in size in relation to the outer diameter of the other of the at least two of the plurality of intermediate components, and (ii) an inner diameter that is uniform in size in relation to the inner diameter of the other of the at least two of the plurality of intermediate components; a plurality of bearing components, each of at least two of the plurality of bearing components having (i) an outer diameter that is uniform in size in relation to the outer diameter of the other of the at least two of the plurality of bearing components, and (ii) an inner diameter that is distinct in size in relation to the inner diameter of the other of the at least two of the plurality of bearing components; disposing the selected intermediate component of the kit within a first cavity of the selected outer shell component of the kit; and disposing the selected bearing component of the kit within a second cavity of the selected intermediate component of the kit, wherein the selected outer shell component is one of the at least two of the plurality of outer shell components, wherein the selected intermediate component is one of the at least two of the plurality of intermediate components, and wherein the selected bearing component is one of the at least two of the plurality of bearing components.
