Title Front & Rear Differential Noise & Oil Leaks
Last Modified 03-MAR-2009 12:23
Category: Driveline
Symptom: 509000 Axle Concerns
Content: Front & Rear Differential Noise, Minor Oil Seal Leak & Debris in Oil.
Concern: Noise (Whine or humming) from the front or rear differential. A minor oil leak may be evident with possible debris in oil. Oil will be black in color.
Cause: The casing black paint /sealer degrades, detaches and contaminates the oil.
This results in the oil overheating which results in oil seal leaks and bearing noise.
Note: Differentials from the VINs quoted below are manufactured with a new casing paint which overcomes the above mentioned issues.
Please only raise an EPQR for differential issues which occur post the quoted VIN numbers:
