Middle of nowhere. Flashers on. Engine codes are screaming. We’ve rolled up on that scene hundreds of times. When your diesel rig quits in the middle of I-80, you need a fix that sticks. That’s what we do. Our mobile diesel trucks are stocked, staffed, and out the door fast – ready immediately to tackle coolant leaks, forced regens, electrical fails, air leaks, and more.
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 University Park 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.

You don’t need to search far for a Diesel Mechanic who actually shows up prepared. We’ve built our business on rolling directly to you with everything necessary to diagnose and fix the issue roadside. Our mobile crews know the roads between University Park and University Park by heart. They’ve handled mid-haul breakdowns outside Falls Creek, after-hours calls in Luthersburg, and long-wait turnarounds off exit 120. If the truck can be fixed where it stands, we’ll make it happen right there.
We keep common parts stocked, and we know which issues tend to show up in this region. Our team will show up, run the diagnostics, and start the repairs right away. We come out, plug in, climb under, and fix what’s stopping you. If the truck needs a tow, we get that moving, too. We’re direct about what’s wrong and clear about what’s next. For us, nearby doesn’t mean close on a map; it means immediately ready to respond.
Step inside, and you’ll hear work in motion: lifts humming, wrenches hitting steel, air lines snapping into place: it’s the sound of trucks getting ready for the next run. Our bays handle the big jobs that roadside service can’t: engine tear-downs, turbo swaps, radiator installs, suspension rebuilds, and wiring overhauls. Each stall is stocked for heavy diesel repair, from axle work to full structural restoration. Nothing sits idle here.
We’ve earned University Park’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?
