New Lenox is a major Will County freight hub. Fleet operators here need a repair partner who diagnoses to the root and quotes the rate before touching anything.
J&A Fleet Maintenance provides mobile diesel repair and emergency roadside service in New Lenox and the surrounding Will County. When your truck can’t move, we come to you — roadside, yard, or dock — with a quoted rate and a certified tech.
Our 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.

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.
Shop Work — New Lenox shop.
For repairs requiring a full shop facility — transmission rebuild, major engine work, welding and fabrication, DOT inspections — our New Lenox shop handles the work. We coordinate transport if needed.
