Constant Noise

Cause

Correction

Inspect for the proper transaxle and gear oil levels prior to performing system diagnosis. Refer to Transfer Case Fluid Replacement .

Low gear oil level

Inspect the transfer case for leaks, repair as required. Refer to Transfer Case Leak Diagnosis and Adhesives, Fluids, Lubricants, and Sealers .

Incorrect gear oil in the transfer case case

Replace the gear oil. Refer to Adhesives, Fluids, Lubricants, and Sealers .

Worn propeller shaft constant velocity joints

Replace the propeller shaft assembly. Refer to Propeller Shaft Replacement .

Worn bearing in the differential assembly

Repair or replace the assembly as required.

Bearing noise within the transfer case

    • A grinding noise that occurs at a specific engine speed, regardless of transmission gear, is not within the transfer case.
    • A grinding noise that changes as a transmission shift occurs is not within the transfer case.
    • 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.
  1. Inspect for the proper fluid level. Fill, as required.
  2. Identity the location of the noise using the CH-39570 Chassis Ears .
  3. If the noise continues, repair or replace the internal components, 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 transfer case.
    • A whine noise that changes as a transmission shift occurs is not within the transfer case.
    • 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 tyres.
  1. Inspect for the proper fluid level. Fill, as required.
  2. Identity the location of the noise using the CH-39570 Chassis Ears .
