Abnormal noise (at turning and accelerate) (AWD) (2016 2017 2018 2019 2020)

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

  • -

    Excessive backlash (hypoid gear)

  • -

    Excessive backlash (differential gear)

  • -

    Differential side gear spline (wear)

• 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

• Pump noise (at lubrication)
• • -

    Debris in pump

  • -

    Rotor (wear or damage)

• Rear differential pump motor noise
• • -

    Bearing (wear or damage)

  • -

    Debris in rear differential pump motor

• Pump noise (at control)
• • -

    Debris in pump

  • -

    Rotor (wear or damage)

• Rear differential solenoid valve noise
• • -

    Debris in rear differential solenoid valve

  • -

    Plunger area or shaft area (wear)

  • -

    Rear differential solenoid valve (wear or damage)

• Clutch chatter
• • -

    Fluid deterioration

  • -

    Clutch facing (burnt or deterioration)

  • -

    Clutch plate (deterioration)

• Loose or missed torqued parts
