Kentucky Manufacturing Co.
The problem
ON CERTAIN VAN TYPE TRUCK TRAILERS (45') EQUIPPED WITH STEMCO "PRO-TORQ" AXLE NUT ASSEMBLIES THAT WERE SOLD ONLY TO ONE CUSTOMER, UNITED PARCEL SERVICE, THE KEEPERS/LOCK RINGS WERE MISSING ALLOWING THE AXLE NUT TO COME LOOSE CAUSING WHEEL OIL TO LEAK OUT.
Risk
THIS COULD EVENTUALLY ALLOW THE HUB, DRUM, AND WHEEL ASSEMBLY TO SEPARATE FROM THE TRAILER, INCREASING THE RISK OF A CRASH.
What owners should do
UPS HAS INSPECTED ALL 300 TRAILERS AND ANY TRAILER FOUND TO BE MISSING THE KEEPER/LOCK RINGS WILL BE CORRECTED.
