 Wheel-End Components


Keeping our customers' vehicles up and running is a critical focus. Maintaining a high fill rate on our Meritor wheel-end offering gives customers the flexibility to order a part today, and receive it tomorrow. And, we are continuously maintaining, reviewing and updating our catalogs to provide you with the best technical expertise and support available. 


One of the great challenges for truck and trailer component manufacturers is reducing weight without sacrificing strength and durability. We meet this challenge with our Meritor hub, the lightest standard ductile iron hub in the industry.

Pound for pound, Meritor hubs are as strong or stronger than other ductile iron hubs and much more durable than aluminum hubs.


  • Engineered using ductile iron instead of aluminum to provide more than 50 percent improvement in both tensile and yield strength
  • No heating requirements for bearing cup replacement, unlike aluminum hubs; this means reduced maintenance time
  • Higher strength threads to significantly reduce the likelihood of stripping, which can result in oil leaks and catastrophic bearing failures
  • Expansion rate compatibility with steel bearing cups to help ensure proper fitting
