Recall 10V199 covers 335 2010 Mci D4000, D4005, D4500, D4505, E4500, J4500 coaches for loose axle bolts. Dealers repair them free.
Mci is recalling 335 2010 D4000, D4005, D4500, D4505, E4500, and J4500 motor coaches because hub, rotor, and wheel adapter bolts on ArvinMeritor front and tag axle assemblies were not torqued correctly. Reduced bolt torque can let vibration loosen the bolts, leading to wheel loss and higher crash risk; the Mci dealer repair will be free once available.

What's wrong?
The axle assembly on these 2010 Mci D4000, D4005, D4500, D4505, E4500, and J4500 motor coaches carries the wheel-end parts that keep the coach rolling and braking in line. The hub, rotor, and wheel adapter are clamped together by bolts tightened to a set torque, which means a set amount of clamping force.
On the affected front and tag axle assemblies, the hub, rotor, and wheel adapter bolts were not tightened enough during assembly. With less clamping force than designed, normal road vibration loosens the bolt instead of leaving the joint tight. Once that joint moves, the wheel-end hardware no longer holds the rotor and adapter as intended.
There is no warning sign before failure. The recall information does not list a driver symptom, so owners should not wait for noise, vibration, or a dashboard alert before having the axle hardware checked.
Who's affected?
The scope spans 6 coach models, all tied to the drive axle.

A matching year and model does not guarantee inclusion. Check your VIN to confirm whether this recall applies to your specific bus.
What's the safety risk?
A wheel separating from the motor coach increases crash risk. If the coach feels unstable or a wheel problem is suspected, stop service and call a franchised Mci dealer for guidance before moving it again. Repair will be free at any franchised Mci dealer once available.
What should I do?
- Check your VIN to confirm your 2010 Mci D4000, D4005, D4500, D4505, E4500, or J4500 motor coach is included in this recall.
- Use the owner letter Mci mailed on May 28, 2010, then contact a franchised Mci dealer for repair instructions.
- Schedule the free axle-assembly bolt-torque repair that prevents hub, rotor, and wheel-adapter bolts from loosening.
- Reference recall number 10V199 when you call Mci or the dealer.
- Avoid operating the motor coach if wheel vibration or looseness is present, and ask the dealer for transport guidance before moving it.
What happens at the repair
At the dealer, an Mci technician repairs the affected motor coach axle assemblies free of charge. The filing identifies ArvinMeritor front and tag axle assemblies where the hub, rotor, and wheel adapter bolts received improper torque during assembly. The repair addresses the loosened or under-torqued bolt condition on the affected axle hardware. The source says the safety recall began on May 28, 2010, but this section data does not mark the remedy as available, so confirm scheduling with an Mci dealer. The dealer repair will be free once available.
