Defect
VEHICLE DESCRIPTION: TRUCKS ASSEMBLED WITH SKF LEVEL 2 TRUCK HUB UNITS (THU) RECEIVED FROM MERITOR. THESE HUBS CAN FATIGUE CRACK.
Consequence
THIS FATIGUE CRACKING CAN RESULT IN WHEEL SEPARATION, INCREASING THE RISK OF A CRASH.
Remedy

Defect
VEHICLE DESCRIPTION: HEAVY DUTY TRUCKS EQUIPPED WITH PROSLEEPER BUNKS. A MICRO RELAY LOCATED BEHIND THE HVAC CONTROL PANEL IN THE BUNK CAN CORRODE FROM MOISTURE.

Remedy
DEALERS WILL REMOVE THE EXISTING RELAY AND REPLACE IT WITH A SEALED RELAY.
The record is thin — 0 NHTSA complaints — so owner-report data can't strongly confirm reliability either way, though 2 recalls should be verified as completed.
