Truck Repair in San Bernardino
San Bernardino is one of the Inland Empire's freight crossroads, where I-10, I-215 and Highway 210 meet and where distribution fleets stage around the clock. A truck down in that flow costs money by the hour. LA Trucks and Tractors serves San Bernardino truck operators from our Fontana shop at 14166 Whittram Ave, a short run west on I-10, with heavy in-house capability most road shops do not have: diesel engine work, transmission and differential rebuilding, gear manufacturing and a full hydraulic bench under one roof.

Drivetrain-deep truck repair, not just code reading
We go past the fault code. No-start and drivability problems are diagnosed in order; transmissions are torn down and measured rather than exchanged on suspicion; differentials are rebuilt with gearing set to specification — and when a gear set is discontinued, our own gear shop cuts it. That depth matters for San Bernardino fleets running older, proven trucks alongside new ones: the truck you own gets repaired on its merits, with free pick-up and delivery and a quote written from inspection findings.

Frequently asked questions
Do you repair semi trucks for San Bernardino operators?
Yes — Class 8 tractors, dump trucks, water trucks and medium-duty work trucks are core work: engines, transmissions, differentials, PTO and hydraulic systems, diagnosed and rebuilt at our Fontana shop serving San Bernardino.
My truck has a no-start problem. Can you diagnose it?
Yes. We work no-starts in a disciplined order — fuel, air, cranking, electrical and control systems — and quote from what the diagnosis actually finds rather than replacing parts until it starts.
