Commercial truck and trailer repair, on site, across Oakland and the East Bay. Diesel, hydraulic, brake, and electrical.

On-Site Truck Repair That Eliminates the Shop Trip
A commercial truck that needs repair does not need to be towed to a shop and wait for an available bay. That model made sense when mobile service trucks did not carry the diagnostic equipment and parts inventory to handle serious work in the field. That is not the case anymore. We bring factory level diagnostics for every major engine platform, a full inventory of common parts, and the tools to handle everything from a brake job to a complete diesel engine diagnosis right where the truck is parked.
Our mobile truck service covers Oakland, the Port of Oakland corridor, and the entire East Bay. Fremont, Hayward, Richmond, Concord, and everywhere in between. If a truck is down and needs to be running again, call 510-937-3978.
Port of Oakland and Freight Corridor Work

Oakland is a port city, and that shapes the kind of truck work we see every day. Container chassis cycling between the port terminals and the warehouses along the 880 corridor take a beating from the volume and the tight maneuvering in terminal yards. Lighting problems, tire damage, twist lock issues, and suspension wear are the constant calls on chassis work.
The drayage trucks pulling those chassis run short haul routes that are brutal on engines. Low speed, high idle time, constant stops. Those conditions are the worst scenario for DPF regeneration, and drayage operators in the East Bay deal with more aftertreatment system problems per mile than almost any other type of trucking operation. CARB enforcement at the port adds urgency to keeping emissions systems compliant.
What Our Mobile Diesel Mechanics Handle
The short answer is most things that would otherwise require a tow and a shop visit. The detailed list:
Diesel engine diagnostics and repair. Factory scan tools for Cummins, Detroit, Paccar, International, Volvo. Live data, fault histories, parameter verification. Not generic code readers that give you a number and no context.
S-Cam and Air Brake Service. Adjustment, shoe and drum replacement, chamber repair, slack adjusters, ABS diagnostics, air system leak testing. CHP commercial enforcement is active on the 880, 580, and 80 through the East Bay.
Radiator, Thermostat, and Coolant Service. Overheating diagnosis, radiator service, water pump replacement, thermostat testing, fan clutch inspection. East Bay summers get hot enough to push marginal cooling systems past their limit.
CARB emissions and aftertreatment. DPF diagnostics, forced regeneration, SCR system evaluation, DEF system repair, NOx sensor testing. California compliance with factory data to prove it.
Hydraulic systems. Dump trucks, concrete pumpers, roll off trucks, crane trucks. Cylinder repair, pump diagnosis, valve troubleshooting, hose replacement.
Electrical troubleshooting. Starting and charging systems, CAN bus faults, wiring repair, lighting. The salt air from the bay accelerates corrosion on electrical connections in ways that inland trucks do not deal with.
Liftgate repair. Hydraulic and electric liftgates on delivery trucks and box trucks. Motor, pump, cylinder, switch, and wiring problems.
Trailer repair. Dry vans, flatbeds, reefers, chassis. Suspension, doors, landing gear, lighting, kingpin.
Roadside Commercial Tire Service. Roadside and yard tire mounting, flat repair, replacement.
Fleet Preventive Maintenance

For operators running multiple trucks out of the East Bay, scheduled preventive maintenance at your yard is the most efficient way to keep your fleet legal and reliable. We come to your facility on a regular schedule, inspect and service each unit, and document everything for your California BIT compliance records.
The alternative is waiting for things to break and then dealing with emergency roadside calls. That costs more, takes longer, and disrupts your operation. A good PM program does not eliminate all breakdowns, but it catches the problems that are building up before they strand a truck somewhere.
