When the dash lights up, the clock starts ticking. We have no time to lose. Our mobile mechanics load up and roll out, ready to tackle the problem where it happened: on an icy grade, in a pull-off by the weigh station, or outside a logging site where cell service barely holds. Some days it’s a coolant hose that splits open mid-run; other days, it's an air leak that drains the system before the brakes release. We’ve chased these problems in every season, often with snow hitting sideways or summer heat bouncing off the asphalt.
Each service truck carries everything needed to diagnose and repair on-site, including electrical gear, air fittings, spare hoses, and stocked tires. If the fix needs more room, we tow the truck to our Yarnell facility and move straight into the teardown process. Engines, radiators, and turbo systems get pulled and rebuilt by the same crew that answered the call. No delay. No handoff. Just work done until the truck moves again.

"Near me" means nothing if no one shows up. That’s why when you call us, we answer—and we roll. Doesn’t matter if you’re stuck by the off-ramp at Exit 123 or limping toward a lot in Clearfield. We’re already halfway there. We handle the big-ticket diesel jobs: U-joints, axle seals, brake systems, lighting, wiring, diagnostics; plus all the head-scratching issues that don’t show up on a scan tool. Our mechanics are hands-on and field-tested.
We stay in tune with the rhythm of the road. Drivers call because they know what to expect—fast answers, no runaround, and fixes that hold past the next weigh station. Some of our calls start with a stressed dispatcher and end with a driver back behind the wheel before dawn. Others turn into repeat routes, familiar faces, and quick nods at the pump the next time through town. Around here, word travels fast when a crew keeps trucks moving.
We’ve got trucks in our shop that could tell stories. Local haulers, cross-country rigs, loggers, dumpers, you name it. Our Yarnell location is where real diesel work gets done. No polish, no fluff, just 40,000 square feet of space, stocked parts, and a crew that turns wrenches like clockwork. Wiring nightmares? Bring it in. Brake failures? Handled. Suspension issues, axle spindle replacements, structural welding, we take the tough jobs because that’s who we are.
We’ve earned Yarnell’s trust by fixing what others misdiagnosed. That’s why independent haulers, local companies, and even other shops send diesel work our way. Cooling system failing under load? Exhaust throwing codes with no apparent cause? We’ll chase it down and explain the fix. Not upsold, not brushed off, just straight diesel repair, built for people who actually rely on their trucks to make a living.
Our diesel services cover the full system, front to back. We handle mechanical repair, maintenance, and diagnostics, as well as oil changes, brake jobs, and wiring work. We fix leaks that hide under the hood, regen issues that stall production, and electrical shorts that fry your dash lights. We even stock the parts most drivers end up needing on the spot. That way, if you limp in with an air or coolant leak, we can patch, seal, and refill before the truck cools. When the repair calls for heavier work, the rig rolls inside. We take care of turbochargers, exhaust systems, radiators, and complete cooling system overhauls. Welding and fabrication happen onsite for cracked mounts or damaged structural components. Each repair is logged and double-checked before it leaves the bay.
