Mobile Repair — Workshop-Grade Service, On-Site at Your Yard
When a unit goes down, Legacy Fleet Care comes to your yard across greater Lawrenceville and the wider Northeast Atlanta area. Workshop-grade diagnostics, on-site repairs, and the same technician (Joseph) from the first call through the same-day fix — no tow needed.
What We Bring to Your Yard
Two things on every mobile repair call
The mobile repair promise is that the same diagnostic depth and the same repair capability you'd get in a shop bay shows up at your dock. These are the two halves of every visit — we run both, on the same trip, before we hand the truck back.
Scan-tool level reads, multimeter, and the same fault-code walk a shop would run — we pull the code, confirm the circuit on the truck, and tell you what failed before we quote the repair.
Brakes, air-ride, aftertreatment, electrical, fuel system, and component replacement — done at your dock, yard, or job site. Stock van with the parts that fail most often; specialty parts called in ahead of the visit.
Fleet Types We Service
Tractors, trailers, forklifts — and the unit in between
Mixed commercial fleets across greater Lawrenceville pull from this list — single and double-axle tractors, box trailers, beverage trailers, and the yard forklifts that move them around. Each card below is a service area we already run from the mobile van.
Single-Axle Tractors
Day-cab and straight-truck power units — single-axle configurations for last-mile, beverage, and retail delivery fleets yard-dotted across greater Lawrenceville.
Double-Axle Tractors
Sleeper and tandem-axle power units running heavier loads — same technician, same diagnostic tooling, same mobile tooling on-site so a repair doesn't mean a tow and a shop queue.
Box Trailers
Dry van and storage trailer repairs — roll-up doors, roof panels, side skins, landing gear, and brake / light systems on the trailer that round out your tractor pool.
Beverage Trailers
Delivery-fleet beverage trailers — multi-compartment bodies, refrigeration units, lift gates, and the lights / brakes a route-driven trailer needs to stay road-legal between drops.
Forklifts
Yard and loading-dock forklifts — propane, diesel, and electric — hydraulic, mast, and electrical faults repaired on-site so the dock keeps moving while the fix is in progress.
Diagnostic Depth on the Truck
What the scan tool, multimeter, and pressure gauges cover
These are the diagnostic areas walked on every mobile call — fault-code reads, circuit traces, and spec comparisons done at the unit before we recommend a part. We walk them, we log them, and we read them against make-specific service information.
Engine
Cylinder contribution, fuel-pressure readings, oil-pressure drop-tests, and on-truck scan-tool walks for Detroit, Cummins, and Powerstroke powerplants.
Electrical
Parasitic-draw tests, body-harness fault isolation, alternator / starter drop-tests, and lighting / signal wiring laid out with a meter before parts are swapped.
Aftertreatment
DPF regen / soot-load reads, DEF system and sensor faults, SCR efficiency walk, and forced regen command on Cummins and Detroit aftertreatment modules.
Brakes & ABS
Service brake measurements, slack-adjuster stroke, air-pack leaks, ABS sensor / module blinks, and trailer ABS pairing walked before the unit rolls out of your yard.
Air-Ride
Air-bag inflation timing, height-control valve reads, and compressor cut-in / cut-out pressures — captured against manufacturer spec, not the symptom you called in about.
Cooling & HVAC
Cooling-system pressure tests, fan-clutch engagement, cab HVAC blend-door / refrigerant checks, and belt / hose walk before a part is replaced.
