When your semi breaks down in Luna Pier, every minute costs money. You need someone who understands that your livelihood depends on getting back on the road quickly.
That’s exactly what you get with J&J Truck & Trailer Repair. We bring the shop to you with fully equipped mobile units, so there’s no waiting for a tow truck or sitting in line at a repair facility. Our technicians diagnose the problem on-site and fix it right the first time.
You’ll know exactly what’s wrong, how much it costs, and when you’ll be rolling again. No surprises, no runaround, just honest service that gets results.
We’ve been the go-to choice for Luna Pier area truckers since 1984. We’re not some fly-by-night operation or national chain that treats you like a number.
Dr. Phillip Marin leads our team with three Ph.D. degrees in Diesel Engineering, Drivetrains, and Metal Alloys. When he looks at your truck, he’s seeing things other mechanics miss. That expertise means faster diagnosis, better repairs, and fewer callbacks.
We know the I-75 corridor, US-24, and Telegraph Road like the back of our hands. When you call, we know exactly where you are and the fastest way to get there. That local knowledge makes all the difference when you’re stuck on the side of the road.
Here’s how we get you back on the road. You call our dispatch line and tell us where you are and what’s happening with your truck. We’ll ask a few quick questions to send the right equipment and parts.
Our mobile unit arrives with diagnostic equipment and common repair parts. We run a complete system check to identify the root cause, not just the symptom. You’ll get a clear explanation of what’s wrong and an upfront price before any work starts.
Most repairs happen right there on the spot. If we need specialty parts, we’ll get your truck to a safe location and have you running again as soon as possible. Every job includes a follow-up to make sure everything’s working properly.

We handle everything from simple jump-starts to complex engine diagnostics. Our mobile units carry equipment for brake repairs, air system fixes, electrical troubleshooting, tire changes, and fuel delivery. If your reefer unit goes down, we can get temperature-controlled loads back to proper conditions.
Luna Pier’s location along major shipping routes means trucks here work hard. The constant stop-and-go traffic from Detroit to Toledo puts extra stress on brakes and transmissions. We see these patterns every day and stock parts accordingly.
Fleet managers choose us because we understand their bottom line. Every hour of downtime costs money, so we focus on permanent fixes that prevent repeat failures. Our fleet discount programs and priority scheduling help keep your operation running smoothly year-round.
We typically arrive within 45 minutes to 1 hour for emergency calls in the Luna Pier area, depending on your exact location and current road conditions. Our dispatch system tracks the closest available technician to your breakdown location.
For calls along I-75, US-24, or Telegraph Road, response times are usually faster since these are major routes we service regularly. We maintain mobile units strategically positioned throughout the Detroit metro area to minimize response times.
If you’re dealing with a safety issue or blocking traffic, let our dispatcher know immediately. We can often expedite service or coordinate with local authorities to ensure everyone stays safe while we’re en route.
Our mobile units handle about 85% of common truck breakdowns right at your location. This includes diesel engine diagnostics, brake system repairs, electrical problems, air system leaks, starter and alternator replacement, battery service, and tire changes.
We carry diagnostic computers that work with all major truck manufacturers – Freightliner, Peterbilt, Kenworth, Volvo, Mack, and International. For complex transmission work or major engine rebuilds, we’ll get your truck to our shop or coordinate with a trusted facility.
The key is our diagnostic capability. Even if we can’t complete the repair on-site, we can usually identify the exact problem and give you accurate cost estimates before any major work begins. No guesswork, no surprise bills later.
Yes, we provide round-the-clock emergency service 365 days a year. Fleet customers get priority scheduling and dedicated account management to streamline the repair process when drivers call in breakdowns.
Our fleet programs include volume discounts, consolidated billing, and detailed repair reports that help you track maintenance patterns across your equipment. We understand that fleet managers need documentation for DOT compliance and budgeting purposes.
For established fleet accounts, we can set up direct billing arrangements so your drivers don’t need to handle payments in the field. This speeds up service and reduces paperwork for everyone involved.
Our diagnostic service uses factory-level scan tools to read fault codes from your truck’s ECM, transmission controller, ABS system, and emissions components. We don’t just read codes – we interpret them based on operating conditions and maintenance history.
The diagnostic process includes checking fuel system pressure, turbocharger operation, EGR valve function, and DPF regeneration cycles. We’ll test sensor readings against manufacturer specifications to identify failing components before they cause major damage.
You’ll receive a written report explaining what we found, which components need attention, and recommended repair priorities. This helps you make informed decisions about immediate fixes versus scheduled maintenance items that can wait.
Our mobile service rates are competitive with shop-based repairs, and often save money when you factor in towing costs and downtime. We provide upfront pricing before starting any work, so you know exactly what repairs will cost.
For routine maintenance and complex repairs, our shop rates are typically 15-20% below dealer pricing while maintaining the same quality standards. We use OEM or equivalent parts and back our work with comprehensive warranties.
The real value comes from preventing small problems from becoming major failures. Our diagnostic expertise often identifies issues that other shops miss, saving you thousands in potential engine or transmission damage down the road.
Yes, we service refrigerated trailers and can handle most cooling system emergencies in the field. This includes compressor belt replacement, refrigerant leaks, temperature sensor problems, and electrical issues with the reefer unit.
For temperature-controlled loads, we understand that time is critical. We carry common reefer parts and can often get your cooling system running again within an hour. If major compressor work is needed, we’ll help coordinate with specialized reefer shops.
Our technicians are trained on Carrier, Thermo King, and other major reefer brands. We can perform emergency repairs to maintain load temperature while arranging for permanent fixes at appropriate facilities. Your cargo stays protected while we solve the problem.
