Why Must the Half Shaft Be Replaced with an Original Equipment Manufacturer (OEM) Part?

[VonCharles]

Half Shaft Must Be Replaced with OEM Part Because OEM Parts Are More Durable and Stable. The Importance of the Half Shaft: One of the Most Critical Components in the Engine. It Bears the Force Transmitted by the Connecting Rod and Converts It into Torque, Which Is Then Output Through the Crankshaft to Drive Other Engine Accessories. The Crankshaft Is Subjected to Centrifugal Forces from Rotating Masses, Periodically Varying Gas Inertial Forces, and Reciprocating Inertial Forces, Causing It to Endure Bending and Torsional Loads. Therefore, the Crankshaft Must Have Sufficient Strength and Stiffness, with Wear-Resistant Journal Surfaces, Uniform Operation, and Good Balance. The Structure of the Half Shaft: To Reduce the Mass of the Half Shaft and the Centrifugal Force Generated During Operation, the Crankshaft Journals Are Often Hollow. Oil Holes Are Drilled on Each Journal Surface to Allow the Introduction or Removal of Oil for Lubricating the Journal Surface. To Minimize Stress Concentration, the Connections Between the Main Journal, Crankpin, and Crank Arm Are All Designed with Transition Radii.
