24/7 Mobile Truck Repair

When your truck breaks down, it’s never convenient — it’s usually late, you’re loaded, and the customer’s waiting. That’s why TJ’s Fab & Mobile Repair built a true 24/7 mobile truck repair service for professional drivers and fleets that need reliability, speed, and heavy-duty expertise anywhere in the Memphis metro and Mid-South region. From the shoulder of I-40 or I-55 to the back lot of a shipper, we respond fast with fully equipped service trucks and technicians trained for diesel engine, electrical, brake, and air system repairs on Class 6–8 tractors and trailers.

We understand downtime equals lost revenue, so every call is handled with urgency. Dispatch gives you real ETAs, and the technician who shows up is ready to diagnose, repair, and get you moving — not just “look at it.”

We handle:

  • Engine no-starts, crank-no-start diagnostics, injector and fuel-system issues

  • Electrical faults, shorts, lighting and harness problems, fuse and relay issues

  • Air-brake problems, leaking lines, broken fittings, air-bag and governor failures

  • Brake chambers, slack adjusters, S-cam repairs, and foundation brake service

  • Cooling system leaks, failed hoses, clamps, belts, thermostats, and water pumps

  • Charging system failures, alternators, starters, and battery service

  • Wheel-end failures, hub-seal replacements, bearings, and spindle issues

  • DEF/after-treatment derates, sensor faults, dosing pump and line service

  • Transmission leaks, clutch adjustments, linkage repairs, and shift diagnostics

  • Suspension issues, leaf-spring and torque-arm repairs, bushings, and mounts

Our service trucks carry diagnostic computers, air and electrical tools, shop-quality jacks, and common parts — so most jobs are completed roadside or dockside without a tow. We’re prepared for both emergency truck repair and scheduled mobile fleet maintenance, offering full invoices, photos, and digital work orders to keep your compliance and recordkeeping seamless.

Coverage Area:
We serve the Memphis metro, West Memphis, AR, Germantown, TN, and surrounding highways including I-40, I-55, US-64, and Hwy 70.
