Cause	Correction
Inspect for the proper transaxle and gear oil levels prior to performing system diagnosis.
Low gear oil level	Inspect the power transfer unit for leaks, repair as required. Power Transfer Unit Case Leak Diagnosis , or Adhesives, Fluids, Lubricants, and Sealers
Incorrect gear oil in the power transfer unit	Replace the gear oil. Adhesives, Fluids, Lubricants, and Sealers
Worn propeller shaft constant velocity joints	Replace propeller shaft assembly. Two-Piece Propeller Shaft Replacement
Worn wheel drive shaft constant velocity joints	Replace the constant velocity joints, as required. Front Wheel Drive Half Shaft Replacement - Left Side , or Front Wheel Drive Half Shaft Replacement - Right Side (AWD) , or Front Wheel Drive Half Shaft Replacement - Right Side (M3U, MHG, MNH, MNK with FWD) , or Front Wheel Drive Half Shaft Replacement - Right Side (M3D, M3H with FWD) , or Rear Wheel Drive Shaft Replacement - Left Side , or Rear Wheel Drive Shaft Replacement - Right Side .
Bearing noise within the power transfer unit A grinding noise that occurs at a specific engine speed, regardless of transmission gear, is not within the power transfer unit. A grinding noise that changes as a transmission shift occurs is not within the power transfer unit. A grinding noise that changes as vehicle speed changes may be also caused by worn wheel bearings. A grinding noise that changes as the vehicle turns may also be caused by worn wheel bearings and/or tires.	Inspect for the proper power transfer unit fluid level. Fill, as required. Identify the location of the noise using the J-39570 Chassis Ears. If the noise continues, inspect the power transfer unit internal components. If damage is present, replace the assembly as required.
Gear set whine noise within the transfer case A whine noise that occurs at a specific engine speed, regardless of transmission gear, is not within the power transfer unit. A whine noise that changes as a transmission shift occurs is not within the power transfer unit. A whine noise that changes as vehicle speed changes may be also caused by worn wheel bearings. A whine noise that changes as the vehicle turns may also be caused by worn wheel bearings and/or tires.	Inspect for the proper power transfer unit fluid level. Fill, as required.
