What are the causes of drive axle damage?

[DelVera]

Drive axle damage causes: 1. Early failure of main reducer, mainly including: early gear wear, gear tooth fracture, early bearing failure of drive pinion, etc.; 2. When bearing clearance is too small or too large, abnormal noise will occur, at which point the main transmission mechanism should be disassembled to readjust bearing clearance; 3. Poor lubrication between differential planetary gears and planetary gear shafts, leading to planetary gear shaft wear and shearing, which may cause serious accidents like rear axle gear chipping. The drive axle consists of main reducer, differential, axle housing, half shafts, wheel side reducer, and hub, etc. Its function is to transmit torque from the drive shaft to the driving wheels, achieving direction change, speed reduction and torque increase.
