J&J Truck & Trailer Repair has been the go-to name for semi truck repair in Highland Park since the early 1980s. We’ve watched this area grow from a manufacturing hub to today’s diverse industrial landscape, and we’ve kept trucks moving through it all.
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 deep technical knowledge that solves problems other mechanics miss. When your Cummins throws a code or your air brake system acts up, you want someone who understands these systems at the molecular level.
Highland Park’s narrow streets and heavy I-75 traffic create unique challenges for truck operations. We know which routes work for emergency service calls and how to navigate the area efficiently when you need help fast.
First, you call us with your location and symptoms. Our dispatcher immediately sends the nearest mobile unit while gathering details about your truck and the problem. No phone tag or callbacks—just immediate action.
Second, our certified technician arrives with a fully equipped service truck. We run diagnostics using professional-grade equipment to identify the exact issue, not just the obvious symptoms. You’ll know what’s wrong and what it’ll take to fix it before any work begins.
Third, we handle the repair on-site whenever possible. Most brake issues, electrical problems, tire changes, and engine diagnostics can be completed right where your truck sits. For complex repairs requiring shop facilities, we coordinate with trusted local partners.
Finally, we complete all paperwork, process payment through your preferred method, and ensure you’re confident about the repair before leaving. Your truck is back in service, and you’re back on schedule.

Most common semi truck problems can be resolved with our mobile repair service. If your truck is drivable but showing warning lights, making unusual noises, or experiencing performance issues, we can usually diagnose and fix the problem on-site. Brake issues, electrical problems, cooling system leaks, and tire problems are typically handled without towing.
You’ll need shop service for major engine work, transmission rebuilds, extensive frame repairs, or any repair requiring the truck to be lifted completely off the ground. However, even in these cases, we can often perform initial diagnostics at your location to determine exactly what’s needed before coordinating shop service.
When you call, describe your symptoms and current situation. Our experienced dispatcher can usually tell you immediately whether we can handle the repair on-site or if shop service will be necessary. This saves you time and helps you make informed decisions about your truck’s repair needs in Highland Park.
