Truck Repair in Pomona
Pomona sits at the junction of I-10, the 57 and the 71, home to the Fairplex, Cal Poly Pomona, rail yards and manufacturing plants whose trucks and work vehicles run the San Gabriel Valley's freight and construction traffic. LA Trucks and Tractors serves Pomona truck operators from our Fontana shop at 14166 Whittram Ave, a short run east 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 Pomona 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.
