Truck Preventive Maintenance

Breakdowns are mostly maintenance that didn't happen

Almost every expensive roadside failure — a cooked engine, a dragged brake, a blown steer tire — announces itself weeks earlier to anyone who looks. Preventive maintenance is the looking.

What a PM service covers here

• Oil and filter service with fluid condition checks — coolant, gear oil, power steering — on intervals matched to how the truck actually works, not a sticker
• Brake inspection — linings, drums, chambers, slack adjusters, and the air system's ability to build and hold pressure
• Tires — wear patterns, pressures, and the irregular wear that points at suspension and alignment problems early
• Chassis lubrication, belts, hoses, and cooling system condition
• Lights, batteries, and charging system health
• Aftertreatment health checks — catching DPF and EGR problems before they become derates

PM that also keeps you legal

A truck maintained on schedule is a truck that passes inspections. We do DOT inspections and CARB inspections in-house, and PM findings feed straight into whatever compliance work the calendar demands.

For one truck or the whole yard

Owner-operators book PM around their loads; fleet customers put it on a schedule and stop thinking about it. Either way it's the same bays, the same mechanics, and mobile service when it's easier for us to come to the trucks.

Where the truck sits matters too

Maintenance is not only what happens on the lift. Yard surface, drainage, shade and how a truck is parked between runs all affect what corrodes and what seizes — see seasonal garage and yard prep for Sacramento truck owners for the practical checklist.

Common questions

How often should a semi truck get a PM service?

It depends on duty cycle — miles, idle time, loads, and terrain. A truck grinding up I-80 grades loaded lives a different life than one running local deliveries. We'll set the interval from how your truck works, then adjust it from what the services actually find.

What's the difference between PM and just an oil change?

The oil change is one line item. The value is the inspection around it — the brake lining that's nearly done, the hose that's soft, the tire wearing on one shoulder. That's what turns a future tow bill into a scheduled repair.

Do you keep maintenance records?

Yes — every service is documented, which matters at inspection time and at resale. Fleet customers get their trucks' history in one place, in one shop's records.
