Axle shaft assemblies for use with a vehicle include a shaft formed from a first material having a first modulus of elasticity for providing the shaft with a flexibility adapted to withstand side impacts and resist deformation. A first end member can be engaged with a first end of the shaft, and a second end member can be engaged with the second end of the shaft. The end members can be formed from a second material having a second modulus of elasticity greater than the first, such that the end members are adapted to withstand a rotational force. The end members can include splined connectors, hub flanges, and other similar components. The resulting axle shaft assembly can thereby include modular combinations of materials having low and high moduli of elasticity.

1. An axle shaft assembly for a vehicle, the assembly comprising: a first shaft having a first end, a second end, and a central portion, wherein the first shaft is formed from a first material having a first flexibility for adapting the first shaft to withstand side impacts and resist deformation;a first splined end member integrally and mechanically engaged with the first end of the first shaft, wherein the first splined end member is formed from a second material having a second flexibility less than the first flexibility, and wherein the first splined end member is adapted to withstand a first rotational force from a drive system and transfer the first rotational force to the first shaft; anda second splined end member integrally and mechanically engaged with the second end of the first shaft, wherein the second splined end member is formed from the second material, and wherein the second splined end member is adapted to withstand the first rotational force transferred from the first shaft. 2. The axle shaft assembly of claim 1, wherein the first material comprises titanium. 3. The axle shaft assembly of claim 1, wherein the second material comprises steel. 4. The axle shaft assembly of claim 1, wherein the first shaft comprises a generally constant outer diameter between the first splined end member and the second splined end member. 5. The axle shaft assembly of claim 1, wherein the first shaft comprises a first diameter, a second diameter, and a taper between the first diameter and the second diameter. 6. A method for providing a vehicle with an axle shaft, the method comprising the steps of: integrally and mechanically engaging a first splined end member engaged with a drive system with a first end of a first shaft, wherein the first shaft is formed from a first material having a first flexibility adapted to withstand a side impact and resist deformation, wherein the first splined end member is formed from a second material having a second flexibility less than the first flexibility, and wherein the first splined end member is adapted to withstand a first rotational force;integrally and mechanically engaging a second splined end member with a second end of the first shaft, wherein the second splined end member is formed from the second material, and wherein the second splined end member is adapted to withstand the first rotational force, a second rotational force, or combinations thereof; andapplying a rotational force to the first end member, thereby rotating the first shaft and the second end member. 7. The method of claim 6, wherein the first splined end member is engaged with a drive system, and wherein the step of applying the rotational force to the first splined end member comprises applying the rotational force to splines of the splined member. 8. The method of claim 6, further comprising the steps of: engaging a third splined end member engaged with a drive system with a third end of a second shaft, wherein the second shaft is formed from the first material and the third end member is formed from the second material; andengaging a fourth splined end member with a fourth end of the second shaft, wherein the fourth end member is formed from the second material,wherein the step of applying the rotational force to the first splined end member further comprises applying the rotational force to the third splined end member, thereby rotating the second shaft and the fourth splined end member. 9. The method of claim 6, wherein the first material comprises titanium. 10. The method of claim 6, wherein the second material comprises steel. 11. The method of claim 6, wherein the first shaft comprises a generally constant outer diameter between the first splined end member and the second splined end member. 12. An axle shaft assembly for a vehicle, the assembly comprising: a shaft having a first end, a second end, and a central portion, wherein the first shaft is formed from a first material having a first flexibility for adapting the first shaft to withstand side impacts and resist deformation;a first splined end member integrally and mechanically engaged with the first end of the first shaft, wherein the first splined end member is formed from a second material having a second flexibility less than the first flexibility, and wherein the first splined end member is adapted to withstand a first rotational force from a drive system and transfer the first rotational force to the first shaft. 13. The axle shaft assembly of claim 12, wherein the first material comprises titanium. 14. The axle shaft assembly of claim 12, wherein the second material comprises steel. 15. The axle shaft assembly of claim 12, further comprising a second splined end member integrally and mechanically engaged with the second end of the first shaft. 16. The axle shaft assembly of claim 15, wherein the second splined end member is formed from the second material.
