J&J Truck & Trailer Repair has been keeping Belleville’s trucking community moving since 1999. As a family-owned business, we understand that your truck isn’t just equipment—it’s your livelihood.
Led by Dr. Phillip Marin, whose three Ph.D. degrees in Diesel Engineering, Drivetrains, and Metal Alloys bring unmatched expertise to every repair, our team serves the critical freight corridors that run through Belleville. From I-94 to I-275, we know these roads and the trucks that travel them.
Our mobile service covers the entire Detroit metro area, but our heart is right here in Belleville—where we’ve earned the trust of owner-operators and fleet managers who depend on reliable, honest service when breakdowns happen.
When you call with a breakdown, our dispatch immediately locates the closest certified mechanic to your position. No phone tag, no delays—just immediate action to get help on the way.
Our mobile unit arrives equipped with diagnostic computers, common parts, and the tools needed for most roadside repairs. Our mechanic runs a full diagnostic to identify the problem, explains what needs to be done, and provides an upfront estimate before starting any work.

Our mobile units handle the full range of semi truck breakdowns that happen on Michigan roads. From diesel engine diagnostics and brake system repairs to electrical troubleshooting and tire changes, we’re equipped for the problems that actually strand trucks.
Belleville’s position at the intersection of major freight routes means we see everything—from overheated engines struggling up I-275 grades to air brake failures in Detroit traffic. Our mechanics know these local conditions and carry the parts that commonly fail in Michigan’s climate.
We also provide reefer trailer repairs for temperature-controlled loads, mobile welding for structural issues, and emergency fuel delivery. For fleet customers, we offer preventive maintenance services and DOT inspections to help prevent roadside emergencies before they happen.
Response times depend on your exact location and current service calls, but we typically reach most Belleville area breakdowns within 45-60 minutes. Our mobile units are strategically positioned to serve the I-94, I-275, and I-75 corridors where most freight moves.
For breakdowns on major routes like Telegraph Road or near the I-94 rest area, response is often faster since these are high-traffic areas we monitor closely. When you call, dispatch will give you an accurate arrival time based on your specific location and current conditions.
Our mobile units handle most common breakdown repairs including brake adjustments, air system leaks, electrical problems, starter and alternator replacement, cooling system repairs, and tire changes. We carry diagnostic computers that work with all major engine brands—CAT, Cummins, Detroit Diesel, Mercedes, and Volvo.
For complex repairs requiring specialized tools or major parts, we’ll provide temporary fixes to get you safely to our shop or arrange towing. The goal is always to get you moving again as quickly and safely as possible, whether that’s a complete roadside repair or getting you to proper facilities.
Yes, our ASE certified mechanics work on all major truck brands including Freightliner, International, Kenworth, Peterbilt, Volvo, Western Star, and others. We also service all types of trailers including dry vans, flatbeds, and refrigerated units.
Our diagnostic equipment interfaces with modern engine management systems, and our experience includes both newer trucks with advanced electronics and older models that many shops won’t touch. Dr. Marin’s specialized engineering background means we can handle complex problems that stump other repair services.
Pricing depends on the specific repair needed, time of day, and location, but we provide upfront estimates before starting any work. There are no hidden fees or surprise charges—you’ll know exactly what the repair will cost before we begin.
Emergency service calls include a diagnostic fee that covers our mechanic’s travel time and initial assessment. If you approve the repair, this fee is applied toward the total cost. We accept cash, credit cards, and most fleet payment systems including Comdata and T-Chek.
Absolutely. We perform DOT inspections and can handle most compliance-related repairs on the spot. If your truck fails a roadside inspection, we can often make the necessary repairs immediately to get you back in compliance and on the road.
Our mechanics understand current DOT regulations and can identify potential issues before they become violations. For fleet customers, we offer scheduled DOT inspections and preventive maintenance to help you avoid roadside enforcement problems.
Yes, we provide true 24/7 emergency service every day of the year. Freight doesn’t stop for weekends or holidays, and neither do breakdowns. Our mobile mechanics are on call around the clock to handle emergency repairs.
Night and weekend calls may include additional fees to cover the emergency service premium, but we’ll explain all costs upfront. Having reliable 24/7 service available means you’re never completely stranded, no matter when or where a breakdown happens.
