On the 2000-2004 Mitsubishi Montero Sport, the Montero Sport transfer case develops internal bearing and chain wear, leading to grinding noises, difficulty engaging 4WD, and eventual failure. The transfer case fluid breaks down faster than the service interval suggests, accelerating wear.

Common Symptoms

  • Grinding noise when engaging 4WD
  • Difficulty shifting between 2WD and 4WD
  • 4WD indicator light flashing
  • Clunking from transfer case area

How to Fix

Change the transfer case fluid every 30,000 miles instead of the factory-recommended interval. Replace the transfer case chain and bearings when noise is detected. A quality rebuilt transfer case is available for complete failures.

Typical repair cost:$800 - $2,500
