What's wrong?
The drive axle assembly on the 2015 Mci D4500 and D4505 motor coaches sends power to the drive wheels and supports key suspension mounting points. One of those mounting points is the hanger bracket, a steel bracket welded to the axle housing. The welds are supposed to keep the bracket fixed to the axle while the coach carries weight and road forces.
On affected coaches, the drive axle hanger brackets are missing welds. Without those welds, the bracket is not fully secured to the axle housing. The bracket can separate from the axle housing, which changes how the suspension and axle stay located under the coach.
Meritor reported no owner warning before the bracket problem. There is no warning sign before failure, so an included coach needs the axle inspected and repaired under recall 15V837.
Who's affected?
Both listed coach models involve the same drive axle component.
