The problem
VEHICLE DESCRIPTION: HEAVY DUTY TRUCKS EQUIPPED WITH MERITOR INTERAXLE DRIVELINE U-JOINTS. DEFLECTOR RINGS, A PART OF THE SYSTEM TO SEAL THE U-JOINTS FROM CONTAMINATES, ARE LOOSE. THIS ALLOWS WATER TO ENTER THE U-JOINT BEARING AREA RESULT IN DILUTION OF THE LUBRICANT, OXIDATION OF THE BEARING AND SEAL SURFACES, AND LOSS OF LUBRICANT.
Risk
IF THIS PROBLEM GOES UNDETECTED, THE INTERAXLE DRIVELINE CAN SEPARATE FROM THE VEHICLE, INCREASING THE RISK OF A VEHICLE CRASH.
What owners should do
DEALERS WILL REPLACE THE U-JOINTS WITH THE CURRENT DESIGN U-JOINTS.
