## NHTSA's summary

Meritor MX EVO 120 Front Drive Axles NHTSA \#20V\-176 Altec is committed to providing our customers reliable products from initial delivery throughout the useful life of the unit. Altec has been notified of a manufacturing recall by Daimler Trucks North America LLC. It is possible that the Meritor MX EVO 120 front drive axles were assembled without oil in the wheel end system. This can result in overheating of the wheel end bearings which can lead to damage and/or seizing of bearings, plastic deformation of components, and eventually wheel end separation from the axle, increasing the risk of a vehicle crash. The inspection and possible repair must be done at the earliest convenience. The inspection and repair repair will be done by an authorized Daimler Trucks North America dealer.
