Mci is recalling 51 2011 J4500 motor coaches because bolts connecting the axle housing to the axle spindle were not properly heat treated, which can reduce joint strength. Reduced spindle joint strength raises the risk of a crash, and the dealer repair will be free once Mci makes it available.

What's wrong?
The tag axle on a 2011 Mci J4500 motor coach is the non-drive axle that helps carry vehicle weight and keep the coach stable under load. In this axle assembly, bolts fasten the axle housing to the spindle, the part that supports the wheel-end components and keeps them held in the right position.
On affected coaches, those bolts were not properly heat treated. Heat treatment gives a bolt the hardness and strength it needs for a high-load joint. If the bolt material is too soft or weak, the connection between the axle housing and spindle loses joint integrity under normal road forces.
There is no warning sign before failure. The filing does not list a noise, light, vibration, or handling symptom that owners can rely on before the axle joint is compromised.

What's the safety risk?
For an included 2011 Mci J4500, reduced joint strength in the axle spindle can weaken the axle connection and increase crash risk. Drive cautiously and contact a franchised dealer for repair timing. Repair will be free at any franchised Mci dealer once available.
What should I do?
- Check your VIN to confirm your 2011 Mci J4500 is included in this recall.
- Contact a franchised Mci dealer and ask whether the free axle-spindle bolt repair is open for your coach.
- Reference recall number 11V190 when you call, and ask about the ArvinMeritor MC16 tag axle assembly listed in the recall.
- Bring the owner notice if you have it, or tell the dealer the notice date was April 14, 2011.
- Avoid carrying passengers until the dealer inspects the axle spindle bolts and restores the joint strength.
What happens at the repair
The source filing does not list a current remedy status, but it says Mci and ArvinMeritor worked to identify owners and perform the recall repair free of charge. At the dealer, an Mci technician handles the tag axle assembly issue on the 2011 J4500, focusing on the bolts that connect the axle housing to the axle spindle. The repair path is tied to the affected ArvinMeritor MC16 tag axle assemblies. Parts and labor are covered under the recall once the dealer confirms the vehicle is included.
