We bring the fix straight to you: air leaks, coolant loss, forced regens, wiring shorts, and other road-killing issues. Because breakdowns rarely happen in perfect spots. More often, it’s along I-80 near exit 123, or on a rain-slicked ramp outside Marengo when your dash lights up with a DEF warning. That’s when our mobile diesel units roll out. Every truck carries tools, diagnostics, and stocked parts so we can chase down the fault and get your rig breathing again. You’ll see us in muddy lots, rest areas, and truck stops all across Marengo County, turning wrenches under floodlights.
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 Marengo 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.
If your search history reads “Diesel Mechanic near me,” chances are something’s leaking, grinding, or refusing to start, and you need real help fast. We’re close to I-80, which means we can reach you quickly and be fully stocked to do more than just look. Our trucks carry the tools for the job, and our techs don’t just inspect. They fix. We handle work on all types of diesel engines, and we’re ready for more than just code scans.
If not, we’ll pull you to the shop ourselves: no third-party handoff, no waiting on another truck. Inside, our technicians cover everything from oil changes and brake replacements to wiring repairs and computer diagnostics. It’s a full-service setup, tuned for heavy diesel work. You can count on us for clear communication and repairs that last long past the first run after the fix.
At our Dale Road shop, trucks come in beat up from the road: tired tires, cracked lines, rusted bolts, and seized brakes. Just name it, we’ve seen it all. The building itself feels like a second home for diesel techs, with bays lined with welding rigs and shelves stacked with new and retread tires in every size from LP22.5 to 445/50R22.5. This is where the challenging jobs happen: structural repairs, frame rail swaps, axle spindle replacements, and complete engine rebuilds. Each step is about getting rigs back to running condition without shortcuts.
We’ve earned Marengo’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 Bigler Boyz Diesel Mechanic services cover everything from day-to-day issues to full-blown breakdowns. Routine maintenance? Oil changes, filters, tires: we knock that out without slowing you down. Serious repairs? Think electrical troubleshooting, frame rail replacements, brake jobs, and cooling system failures. We’ve got the tools, the parts, and the hands to handle it. Need welding or fabrication? We’re built for that, too. You can roll into our shop off I-80, Exit 123, or call for mobile diesel repair, and we’ll bring the tools to you. Downtime is not only annoying but also expensive. That’s why we stay ready, stocked, and sharp. Whether it’s a fleet truck or a single owner-operator, we don’t cut corners or coast through the job. If your diesel rig needs fixing, we’ve got one question: where should we meet you?
