You’re not just getting a tow truck—you’re getting Dr. Phillip Marin’s 40+ years of expertise and three Ph.D. degrees in Diesel Engineering working for you. Most breakdowns get fixed right where you sit, saving you the hassle and cost of a tow to our shop.
When your truck’s down, every minute costs money. That’s why we arrive prepared with the tools, parts, and knowledge to handle everything from dead batteries to complex engine issues on-site. You get back to work faster, your schedule stays intact, and you avoid the downtime that kills productivity.
Our mobile repair approach means you’re not waiting around some shop all day. We come to you—whether you’re stuck on I-75, broken down at a job site, or dealing with a flat tire in a truck stop parking lot.
J&J Truck & Trailer Repair has been the go-to choice for West Monroe and Detroit area drivers since the 1980s. We’re not some fly-by-night operation—we’re the family business that’s seen every type of breakdown, worked on every make and model, and built our reputation one satisfied customer at a time.
Dr. Phillip Marin didn’t just learn this trade through trial and error. His three Ph.D. degrees in Diesel Engineering, Drivetrains, and Metal Alloys mean you’re getting someone who understands the science behind why your truck stopped running and exactly how to fix it right the first time.
We know the Detroit metro area like the back of our hands. From the industrial corridors of Wayne County to the busy highways connecting West Monroe to the rest of Michigan, we’ve been there, fixed that, and helped drivers just like you get back to what matters most.
Here’s how we turn your roadside emergency into just another minor delay. First, you call us at 313-999-3088—day or night, weekend or holiday, we answer. We don’t use answering services or make you wait through a phone tree. You get a real person who understands exactly what you’re dealing with.
Next, we dispatch our nearest mobile unit to your location. We’re not starting from scratch when we arrive—you’ve already told us what’s wrong, we know your location, and we’re bringing the right equipment for your specific situation. Most of the time, we can give you a realistic timeframe right over the phone.
Finally, we diagnose and fix the problem on-site whenever possible. Our trucks are rolling repair shops with diagnostic equipment, common parts, and tools for everything from simple jump-starts to complex engine repairs. If we can’t fix it where you sit, we’ll get you to the right place quickly and affordably.

Our mobile repair service covers the full spectrum of roadside emergencies. Dead batteries, flat tires, fuel delivery, lockout assistance, jump-starts, and mobile mechanical repairs—we handle it all. But we’re not just another roadside assistance company. We specialize in heavy-duty trucks, trailers, and commercial vehicles that other services can’t or won’t touch.
West Monroe’s location puts you right in the heart of Michigan’s transportation network. Whether you’re hauling freight through Detroit, making local deliveries, or just trying to get your pickup truck home after work, breakdowns here mean you’re stuck in an area where traffic doesn’t slow down for your emergency. That’s why our average response time in the West Monroe area is under 30 minutes.
We stock our mobile units based on what actually breaks down most often in this region. Michigan’s weather is tough on vehicles—cold winters that kill batteries, salt that corrodes connections, and temperature swings that cause tire problems. Our trucks carry the parts and equipment that matter most for the real-world problems you face driving in Southeast Michigan.
Our average response time in West Monroe is under 30 minutes, but it depends on your exact location and current call volume. We have mobile units strategically positioned throughout the Detroit metro area, including Wayne County, so we’re never starting from scratch when you call.
When you reach us at 313-999-3088, we’ll give you a realistic timeframe based on your location and our current dispatch situation. We don’t give false promises about arrival times—if we say 20 minutes, we mean 20 minutes. If it’s going to be longer due to weather or heavy call volume, we’ll tell you upfront so you can plan accordingly.
We specialize in heavy-duty trucks, trailers, and commercial vehicles—that’s actually our primary focus. Dr. Marin’s expertise with diesel engines, drivetrains, and the unique challenges of commercial vehicles means we can handle everything from pickup trucks to Class 8 semis, construction equipment, and specialized commercial vehicles that other roadside services won’t touch.
Our mobile units are equipped specifically for heavy-duty work. We carry the diagnostic equipment, tools, and parts needed for commercial vehicles, not just passenger car supplies. Whether you’re driving a delivery truck, pulling a trailer, or operating construction equipment, we have the knowledge and equipment to get you moving again.
Most roadside assistance companies will tell you they need to tow your commercial vehicle to a shop. We fix the majority of heavy-duty breakdowns right where they happen, saving you time and the cost of a commercial tow.
We can handle most common roadside issues right where your vehicle sits. Jump-starts, battery replacement, flat tire changes, fuel delivery, lockout assistance, and many mobile mechanical repairs are all standard on-site services. Our mobile units are essentially rolling repair shops with diagnostic computers, welding equipment, and a comprehensive parts inventory.
For heavy-duty vehicles, we can often handle more complex issues like brake adjustments, hydraulic repairs, electrical diagnostics, and engine troubleshooting that would require towing with other services. Dr. Marin’s advanced training means we can diagnose and fix problems that less experienced technicians would automatically send to a shop.
The situations that require towing are usually major engine failures, transmission problems requiring shop equipment, or damage from accidents. But even then, we can often get you to a shop of your choice rather than wherever the tow truck driver decides to take you.
Yes, we provide true 24/7 service every day of the year. Breakdowns don’t follow business hours, and neither do we. When you call 313-999-3088 at 2 AM on Christmas morning, you’ll get a real person who can dispatch help to your location, not an answering service that takes a message for Monday morning.
Our commitment to round-the-clock service isn’t just about answering the phone—we have mobile units and technicians ready to respond at all hours. Night calls, weekend emergencies, and holiday breakdowns all get the same professional response as a Tuesday afternoon service call.
We understand that for commercial drivers especially, being down over a weekend or holiday can mean missed deliveries, unhappy customers, and lost income. That’s why we maintain full service capabilities around the clock, not just emergency towing.
We provide clear, upfront estimates before starting any work. Our basic service call fee covers diagnosis and simple fixes like jump-starts, lockout assistance, and fuel delivery. More complex repairs are priced based on parts and labor required, but you’ll know the cost before we begin.
We don’t believe in surprise bills or hidden fees. When we arrive, we’ll assess your situation, explain what needs to be done, and give you a firm price for the work. If additional issues come up during the repair, we’ll discuss those costs with you before proceeding.
For commercial vehicles and heavy-duty repairs, pricing varies based on the complexity of the work and parts required. But you’ll never get a bill that’s significantly different from what we quoted. Our goal is to get you back on the road at a fair price, not to maximize our profit from your emergency.
We serve the entire Detroit metro area including Wayne County, with West Monroe being centrally located in our service territory. We regularly respond to calls throughout Southeast Michigan, from Detroit proper to the surrounding suburbs and communities.
Our service area extends along major highways like I-75, I-94, I-96, and connecting roads where commercial traffic is heaviest. If you’re within about 50 miles of our base in Detroit, we can typically provide service, though response times may be longer for distant locations.
For commercial customers with fleets or regular service needs, we can arrange coverage for routes and locations throughout Michigan. We understand that trucks break down wherever they happen to be, not just in convenient locations, so we work with commercial clients to provide coverage that matches their operational needs.
