Probable Cause 

• Gear noise
• • Poor gear mesh between ring gear and drive pinion
  • Hypoid gear (wear or damage)
  • Poor pre-road (drive pinion)
  • Debris in hypoid gear area
  • Fluid level too low
  • Distortion of the differential carrier case

• Bearing noise
• • Bearing (wear or damage)
  • Drive pinion taper bearing (wear)
  • Debris in bearing

• Differential gear noise
• • Side gear and pinion gear (wear or damage)
  • Pinion shaft (damage)
  • Debris in differential gear area

• Clutch chatter
• • Fluid deterioration
  • Clutch facing (burnt or deterioration)
  • Clutch plate (deterioration)

• Loose or missed torqued parts
