Frequently Asked Questions

Yes, Cummins acquired Meritor in 2022 to vertically integrate their powertrain offerings. This means Cummins now offers engine, transmission (through their Eaton JV), and axle products under one roof. The integration promises better powertrain optimization.
It depends on the truck manufacturer. Some OEMs offer axle choices (Meritor or Dana) while others standardize on one brand per model. Ask your truck dealer about available axle options for your specific configuration.
Drive axles typically need fluid changes every 250,000-500,000 miles depending on manufacturer recommendations and operating conditions. Bearings and seals may need attention at 500,000+ miles. A well-maintained drive axle can last the life of the truck (1 million+ miles).
