Function: Transmits torque from transmission output to differential while providing gear reduction for optimal wheel speed/torque.
Key Components:
Hardened Gear Shaft: Case-hardened steel (HRC 58-62) with ground teeth for NVH reduction
Tapered Bearings: Pre-loaded to withstand axial/radial forces
Spline Interface: Precision-cut for zero backlash connection to differential
Failure Modes:
Tooth Pitting: Fatigue wear from shock loads (causes whining noise)
Bearing Spalling: Contaminated lubricant leads to premature failure
Spline Wear: Results in driveline clunk (check rotational play <2°)
Critical Specs:
Gear backlash: 0.08-0.15mm (requires dial indicator measurement)
Bearing pre-load: 0.05-0.10mm shim adjustment typically needed
Pro Tip: Always replace companion flange nut with OEM torque-to-yield spec – reused nuts cause pre-load loss.
