Emergency Mobile Semi Truck Service

Your Downtime Just Got Shorter

You’re not just getting a repair—you’re getting your schedule back. Our mobile service means no expensive towing to a shop, no waiting days for an appointment, and no guessing when you’ll be rolling again.

Most breakdowns get handled on-site within hours, not days. When we can’t fix it roadside, we’ll get you to our shop or recommend the fastest solution to minimize your losses.

The difference is simple: we understand that your truck isn’t just equipment—it’s your livelihood. That’s why we treat every call like the emergency it is for your business.

Westland Semi Truck Mechanics

Four Decades of Diesel Expertise

We’ve been keeping Detroit metro fleets moving since 1999. We’re not the newest shop in town, but we’re the one drivers call when they need it done right.

Dr. Phillip Marin leads our team with three Ph.D.s in Diesel Engineering, Drivetrains, and Metal Alloys. That level of expertise doesn’t just sound impressive—it means faster diagnostics, better repairs, and solutions that last.

Being family-owned in Detroit means we understand this market. We know the routes, the challenges, and what it takes to keep commercial vehicles running in Michigan’s demanding conditions.

Mobile Truck Repair Process

Simple Process, Professional Results

When you call, we dispatch immediately. Our mobile units carry diagnostic equipment, common parts, and tools to handle most repairs on-site. No waiting around wondering what’s happening.

First, we diagnose the problem and give you a clear explanation of what’s wrong and what it’ll cost to fix. No surprises, no upselling—just straight answers about getting you back to work.

If we can fix it roadside, we do it. If it needs shop work, we’ll either tow you to our facility or help you get to the right place for specialized work. Either way, you know exactly what’s next and when you’ll be rolling again.

About J&J Truck & Trailer Repair

Comprehensive Semi Truck Services

Everything Your Fleet Needs

We handle the full range of semi truck repairs: engine diagnostics and rebuilds, brake system service including air brakes and ABS, transmission work, electrical troubleshooting, and complete DOT inspections. Our mobile service covers tire changes, jump starts, fuel delivery, and emergency repairs.

Westland’s location on major freight corridors means we see every type of breakdown. From I-94 to I-275, we’ve handled everything from simple battery failures to complex engine problems. That experience matters when you’re stranded and need solutions fast.

Fleet operators choose us because we understand commercial vehicle demands. We stock parts for popular makes, maintain detailed service records, and work with your maintenance schedules to prevent problems before they happen.

How quickly can you respond to emergency semi truck repairs in Westland?

Our average response time for emergency calls in Westland is 30-45 minutes, depending on your exact location and current traffic conditions. We maintain mobile service units strategically positioned throughout the Detroit metro area to minimize response times.

When you call, we immediately dispatch the nearest available technician with the right equipment for your situation. Our trucks carry diagnostic computers, common repair parts, and tools needed for most roadside repairs.

For true emergencies—like brake failures or situations where safety is a concern—we prioritize those calls and often arrive even faster. We understand that when your semi is down, every minute counts toward your bottom line.

Most common breakdowns can be handled roadside: battery and electrical issues, brake adjustments and minor brake repairs, tire changes, fuel system problems, cooling system leaks, and basic engine diagnostics. Our mobile units carry the equipment to handle about 70% of typical semi truck problems on-site.

Shop work is needed for major engine rebuilds, transmission overhauls, extensive electrical rewiring, major brake system overhauls, and complex diagnostic work requiring specialized equipment. We’ll be upfront about what can be fixed where you are versus what needs shop facilities.

The key is honest assessment. We won’t attempt roadside repairs that should be done in a controlled shop environment, and we won’t recommend expensive shop work for problems we can solve on-site. You get the right repair in the right place.

Yes, we provide true 24/7 emergency service, 365 days a year. This isn’t an answering service—you reach our actual dispatch, and we have technicians available around the clock for genuine emergencies.

Emergency service covers breakdowns that leave you stranded, safety-critical failures like brake problems, and situations where waiting until morning would cause significant business disruption. We understand that freight doesn’t stop moving at 5 PM.

Our emergency rates are clearly posted, and we’re upfront about costs before starting work. No surprise charges just because it’s 2 AM on a Sunday. Commercial operators need predictable costs, especially during unplanned repairs.

We perform complete DOT inspections and handle all compliance-related repairs to keep your fleet legal and safe. Our technicians are trained on current DOT regulations and know what inspectors look for during roadside checks.

Beyond annual inspections, we help with violation corrections, pre-trip inspection training for drivers, and maintenance documentation that satisfies DOT record-keeping requirements. Proper documentation can save you thousands in fines and keep your safety ratings intact.

We also provide guidance on preventive maintenance schedules that reduce your chances of roadside violations. It’s much cheaper to fix potential problems during scheduled maintenance than to deal with out-of-service orders during a DOT inspection.

Dr. Phillip Marin’s three Ph.D.s in Diesel Engineering, Drivetrains, and Metal Alloys give us diagnostic capabilities that most shops simply don’t have. Complex problems that stump other mechanics get solved faster here because we understand the engineering behind the systems.

Our 40+ years in business means we’ve seen virtually every type of failure and developed efficient repair processes. We’re not learning on your dime—we know what works and what doesn’t, which translates to faster repairs and fewer comeback issues.

Being family-owned also matters. Your business success directly impacts our success, so we’re invested in getting you back on the road quickly and keeping you there. Large chains treat trucks like numbers; we treat them like the businesses they support.

Yes, we service reefer units, hydraulic systems, air ride suspension, and other specialized commercial vehicle equipment. Our experience with diverse fleet operations means we’ve worked on virtually every type of specialized system you’ll find on modern semis.

Reefer repairs are particularly critical since temperature-controlled loads can’t wait. We stock common reefer parts and have the diagnostic equipment to quickly identify compressor, electrical, or refrigerant issues. Many reefer problems can be resolved on-site.

Hydraulic systems for dump trucks, flatbeds with tarping systems, and specialized hauling equipment are routine for us. We maintain relationships with parts suppliers for specialized components and can often get critical parts delivered quickly when needed.
