Hear from Our Customers
Your truck sitting idle costs you $1,000-$2,000 per day in lost revenue. That’s why we bring the shop to you instead of making you wait for a tow.
Our mobile repair service gets you back on I-75 and US-24 fast. No waiting at crowded repair shops. No paying for expensive towing. Just quick, professional repairs that keep your business moving.
When we finish the job, you’re not just fixed—you’re confident. Our ASE certified mechanics don’t cut corners, and our fair pricing means no surprise bills that blow your budget.
J&J Truck & Trailer Repair has been the go-to choice for West Monroe truckers since 1999. We’re not some fly-by-night operation—we’re a family business that understands what downtime costs you.
Dr. Phillip Marin leads our team with three Ph.D. degrees in Diesel Engineering, Drivetrains, and Metal Alloys. That’s not just impressive credentials—it’s the kind of expertise that gets complex problems solved right the first time.
We serve the I-75 corridor from Detroit to Monroe, covering West Monroe, La Salle Township, and all the major truck routes. When other services won’t come out or can’t handle the job, we show up ready to work.
You call 313-999-3088 and tell us where you’re stuck. We dispatch our mobile unit immediately—usually within minutes of your call.
Our technician arrives with a fully equipped service truck. We diagnose the problem on-site using state-of-the-art computer diagnostics. Most repairs happen right there on the roadside.
If we can fix it mobile, you’re back on the road in under an hour. If it needs shop work, we’ll tow you to the nearest facility and handle the coordination. Either way, you’re not dealing with multiple companies or waiting around wondering what’s next.

We handle everything from simple tire changes to complex engine rebuilds. Brake repairs, ABS sensor issues, reefer problems, air system failures—if it’s broken on your truck or trailer, we fix it.
West Monroe sits right on the I-75 freight corridor, which means heavy traffic and hard use on equipment. We see more brake wear, suspension problems, and electrical issues here than most places. That experience means we stock the right parts and know the common failure points.
Our mobile units carry inventory for Freightliner, Peterbilt, Kenworth, International, Volvo, and Mack trucks. We also service all major trailer brands and handle Carrier and Thermo King reefer units. Fleet discounts available for multiple vehicles.
We typically respond within 15-30 minutes in the West Monroe area, depending on your exact location and our current call volume. Our mobile units patrol the I-75 corridor regularly, so there’s usually a truck nearby.
When you call 313-999-3088, our dispatcher immediately locates the nearest available technician and gives you an accurate arrival time. We don’t give you vague “sometime today” estimates—we tell you exactly when to expect us.
If we’re dealing with multiple emergencies, we’ll be upfront about wait times and help you prioritize based on your situation. Safety always comes first, but we understand that time is money in your business.
Our mobile units can handle about 80% of common breakdowns right at your location. This includes brake adjustments and repairs, tire changes, battery and alternator replacement, starter repairs, air system fixes, and most electrical problems.
We carry diagnostic computers that work with all major truck brands, so we can pull codes and identify problems quickly. Our trucks stock common wear items like brake shoes, air lines, belts, hoses, and electrical components.
Major engine work, transmission rebuilds, or frame repairs need shop facilities, but we can often get you mobile enough to reach a repair facility under your own power. If not, we’ll coordinate the tow and make sure you’re taken care of.
Yes, we service all major truck manufacturers including Freightliner, Peterbilt, Kenworth, International, Volvo, Mack, and Western Star. Our diagnostic equipment works with Detroit, Cummins, Caterpillar, and Paccar engines.
Dr. Marin’s expertise covers all the major drivetrain and engine systems, so we’re not limited to specific brands. Whether you’re running a new Cascadia or an older Pete, we have the knowledge and tools to get you fixed.
We also work on all trailer types—dry vans, flatbeds, reefers, tankers, and specialty equipment. Our reefer techs are certified on both Carrier and Thermo King units, which covers most of the refrigerated trailers on the road.
Our rates are the same 24/7—no premium charges for nights, weekends, or holidays. We believe in fair, transparent pricing, especially when you’re already dealing with the stress of a breakdown.
Service call rates start at $150, which covers our response and initial diagnosis. Actual repair costs depend on what’s needed, but we give you a clear estimate before starting any work. No surprises on the final bill.
For fleet customers, we offer volume discounts and can set up accounts for faster service. Many of our regular customers save 15-20% compared to our standard rates, plus they get priority response during busy periods.
Absolutely. We handle all types of DOT inspection issues and can often get you back in compliance the same day. Brake violations, lighting problems, air leaks, tire issues—we’ve seen it all and know exactly what inspectors look for.
Our technicians understand the DOT regulations and can explain what needs to be fixed versus what’s just recommended. We focus on getting you legal first, then address any other maintenance items that could prevent future violations.
If you’re stuck at a weigh station or inspection facility, call us immediately. We can often get there within an hour and have you back on the road before your delivery schedule is completely shot. Time is critical with DOT issues, and we treat them as high-priority calls.
Yes, we work with several fleets in the West Monroe and Monroe County area. We can set up preventive maintenance schedules, provide emergency roadside coverage, and even handle some routine service at your facility.
Fleet customers get dedicated account management, priority response, and volume pricing. We can also provide detailed service reports that help you track maintenance costs and identify vehicles that need attention.
Our mobile service is especially valuable for fleets because we can service multiple trucks at your yard, reducing the downtime that comes with driving to a shop. We’ll work with your schedule to minimize disruption to your operations while keeping your equipment road-ready.
