Dwight is a long way from the nearest major city if your truck goes down. Having J&A Fleet in your contacts means you’re not stuck guessing who to call.
J&A Fleet Maintenance provides mobile diesel repair and emergency roadside service in Dwight and the surrounding Livingston County. When your truck can’t move, we come to you — roadside, yard, or dock — with a quoted rate and a certified tech.
For full-shop work — transmission rebuild, major engine work, welding and fabrication, DOT inspections — our Morris shop handles it, with transport coordinated if your truck can’t make the drive itself. We also cover Pontiac and the rest of the I-55 corridor running south out of Livingston County.
Our Fleet Services
- Diesel & Engine Repair – Root-cause diagnostics and repair for all Class 6–8 diesel engines — no guesswork, no unnecessary parts.
- Semi-Truck Roadside Assistance – 24/7 mobile dispatch across northeastern Illinois — certified techs come to your truck, not the other way around.
- Air Brake Repair – Chambers, valves, compressors, and frozen lines — complete air brake system service and DOT compliance.
- Electrical & Alternator – Advanced diagnostics trace electrical faults to the source — wiring, batteries, alternators, and charging systems.
- Cooling, Radiator & A/C – Radiator, coolant system, and cab A/C repair — keeping engines and drivers running at the right temperature.
- Transmission Repair – Automatic and manual transmissions, differentials, and clutches — diagnosed before a single part is ordered.
- Welding & Fabrication– Certified welders for frame repair, trailer structural work, and custom fabrication — shop or roadside.
Pricing — Same Rate Whether You’re Stranded or Not
J&A Fleet quotes our hourly rate, minimum, and any surcharges before we dispatch. The price doesn’t change because you’re stranded. Overcharging a customer in a tough spot is something you’ll never experience with J&A Fleet.
Fleet Maintenance Programs in Dwight
Running a fleet through the Dwight / I-55 / Route 17 corridor? Ask about our mobile maintenance program. We come to your yard on a schedule, keep your units DOT-compliant, and reduce the unplanned downtime that eats into margins.

Dwight is far enough out that a lot of shops won’t make the drive. We do. See a J&A truck rolling through on I-55 and need help? Just ask — that’s coverage, not a coincidence, and it’s the same standard rate and certified tech you’d get calling in from Morris or Joliet.
Fleets calling us into Dwight are usually dealing with one of the same handful of issues we see across Livingston County: electrical and charging faults, air brake components failing in cold weather, or a cooling system problem that won’t wait for a scheduled shop visit. We diagnose it on site and quote the rate before we start, so the number you hear at dispatch is the number on the invoice — no matter how far out the call takes us.
Fleets that run Livingston County more than once or twice a month tend to save money moving from one-off roadside calls to a standing maintenance schedule — same certified techs, same upfront rate, but planned instead of reactive. In Dwight, that means fewer surprise DOT violations from things like worn brake linings or a bad marker light, and less unplanned downtime eating into the load schedule your dispatcher is trying to hold together week to week.
