1. A cover (100) for a universal joint (10) of a driveshaft (5), said cover comprising: a first section (110) having a first section first end (111), a first section second end (112) opposite the first section first end, a first section first edge (113) extending between a first section first end first end-point and a first section second end first end-point, a first section second edge (114) extending between a first section first end second end-point and a first section second end second end-point, a first longitudinal axis (α 1), and a first radius (r 1); a second section (120) having a second section first end (121), a second section second end (122) opposite the second section first end, a second section first edge (123) extending between a second section first end first end-point and a second section second end first end-point, a second section second edge (124) extending between a second section first end second end-point and a second section second end second end-point, a second longitudinal axis (α 1), and a second radius (r 1); at least two cover fasteners (130); and at least one driveshaft fastener (140); and wherein at least a first cover fastener of the at least two cover fasteners is configured to connect the first section first edge to the second section first edge; and wherein the first section first edge is in direct face-to-face contact with the second section first edge; at least a second cover fastener of the at least two cover fasteners is configured to connect the first section second edge to the second section second edge; and wherein the first section second edge is in direct face-to-face contact with the second section second edge; and the at least one driveshaft fastener is configured to connect the cover to the driveshaft or to a yoke (20) of the driveshaft without any portion of the cover contacting the universal joint.

2. The cover of claim 1 , wherein the first section first edge comprises a first section first flange (115), the second section first edge comprises a second section first flange (125), and the first cover fastener is configured to connect the first section first edge to the second section first edge by passing through the first section first flange and into the second section first flange or by passing through the second section first flange and into the first section first flange.

3. The cover of claim 2 , wherein the first section second edge comprises a first section second flange (116), the second section second edge comprises a second section second flange (126), and the second cover fastener is configured to connect the first section second edge to the second section second edge by passing through the first section second flange and into the second section second flange or by passing through the second section second flange and into the first section second flange.

4. The cover of claim 2 , further comprising at least one additional section having an additional section first end, an additional section second end opposite the additional section first end, an additional section first edge extending between an additional section first end first end-point and an additional section second end first end-point, an additional section second edge extending between an additional section first end second end-point and an additional section second end second end-point, an additional section longitudinal axis, and an additional section radius, wherein each additional section first edge comprises an additional section first flange.

5. The cover of claim 1 , wherein the first section second edge comprises a first section second flange (116), the second section second edge comprises a second section second flange (126), and the second cover fastener is configured to connect the first section second edge to the second section second edge by passing through the first section second flange and into the second section second flange or by passing through the second section second flange and into the first section second flange.

6. The cover of claim 5 , further comprising at least one additional section having an additional section first end, an additional section second end opposite the additional section first end, an additional section first edge extending between an additional section first end first end-point and an additional section second end first end-point, an additional section second edge extending between an additional section first end second end-point and an additional section second end second end-point, an additional section longitudinal axis, and an additional section radius, wherein each additional section second edge comprises an additional section second flange.

7. The cover of claim 1 , wherein the first section comprises a first step-down (117) extending from a first position along a first length of the first section to the first section second end, and the second section comprises a second step-down (127) extending from a second position along a second length of the second section to the second section second end.

8. The cover of claim 7 , wherein a portion of each of the first step-down and the second step-down is configured to contact the driveshaft or a slip-joint of the driveshaft when the at least one driveshaft fastener connects the cover to the driveshaft or slip-joint.

9. The cover of claim 7 , further comprising at least one additional section having an additional section first end, an additional section second end opposite the additional section first end, an additional section first edge extending between an additional section first end first end-point and an additional section second end first end-point, an additional section second edge extending between an additional section first end second end-point and an additional section second end second end-point, an additional section longitudinal axis, and an additional section radius, wherein each additional section comprises an additional section step-down extending from a position along a length of the additional section to the additional section second end.

10. The cover of claim 1 , wherein the first section and the second section are each independently composed of a semi-rigid polymeric material.

11. The cover of claim 10 , wherein the semi-rigid polymeric material is polypropylene.

12. The cover of claim 1 , wherein the first section and the second section are each independently composed of a metal material selected from the group consisting of steel and aluminum.

13. The cover of claim 1 , wherein each cover fastener of the at least two cover fasteners is a self-tapping screw.

14. The cover of claim 1 , further comprising at least one additional section having an additional section first end, an additional section second end opposite the additional section first end, an additional section first edge extending between an additional section first end first end-point and an additional section second end first end-point, an additional section second edge extending between an additional section first end second end-point and an additional section second end second end-point, an additional section longitudinal axis, and an additional section radius.

15. The cover of claim 14 , where each additional section is composed of a semi-rigid polymeric material.

16. The cover of claim 15 , wherein the semi-rigid polymeric material is polypropylene.

17. The cover of claim 14 , wherein each additional section is composed of a metal material.

18. The cover of claim 17 , wherein the metal material is selected from the group consisting of steel and aluminum.
