We understand that in commercial transportation, when your truck is parked, your business stops earning. Drivers and fleet managers across Riverside County and the Inland Empire rely on us to diagnose accurately, fix problems right the first time, and provide fair, transparent pricing before work begins.
Today, N & A Diesel Truck & Trailer Repair operates from Corona, California, providing complete heavy-duty diesel engine overhauls, high-pressure fuel system repairs, automated and manual transmission service, and mobile commercial support across Riverside County, San Bernardino County, and Orange County corridors.

Every service starts with state-of-the-art computer diagnostics and rigorous visual inspection. Our technicians carry dedicated tooling for Cummins, Detroit Diesel, PACCAR, Volvo, and International powerplants. We maintain stocked inventory of heavy-duty filters, air system valves, gaskets, sensors, and fluids so routine and emergency repairs finish with minimal turnaround time. You will always receive an upfront quote with no surprise fees.
