What's wrong?

The axle assembly on the 2011 Western Star 4900 is the heavy structure that carries the wheels and transfers load through the truck's power train. A tower bracket is welded to the axle housing, which is the rigid metal tube around the axle components. That bracket helps keep attached axle hardware held in the correct position as the truck moves and carries weight.

On affected trucks, the weld that attaches the tower bracket to the housing was not made correctly during production of the Meritor axle assembly. A weak weld can crack under normal road loads and vibration. Once the weld cracks, the bracket is no longer held to the housing the way it was designed to be held.

There is no warning sign before failure. An owner or driver should not expect a dashboard light, noise, or steering feel to confirm the crack before the axle assembly is inspected.

What happens at the repair

At the dealer, a Western Star technician inspects the Meritor axle assemblies for cracks at the weld that attaches the tower bracket to the axle housing. If cracking is found, the weld is repaired under the recall. The filing says the safety recall began on December 30, 2011, and the inspection and needed weld repair are free of charge. No separate reimbursement plan is listed, so this section does not add reimbursement instructions.
