LaSalle sits along the Illinois River corridor where freight traffic is heavy, and a breakdown can mean hours of lost time.
J&A Fleet Maintenance provides mobile diesel repair and emergency roadside service in LaSalle and the surrounding LaSalle County. When your truck can’t move, we come to you — roadside, yard, or dock — with a quoted rate and a certified tech.
LaSalle fleets also connect us to Marseilles and Ottawa along the same Illinois River corridor — all covered out of our Morris shop and mobile crews for the routes that run this far west.

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 — Morris shop and mobile service
For repairs requiring a full shop facility — transmission rebuild, major engine work, welding and fabrication, DOT inspections — our Morris shop and mobile service handle the work. We coordinate transport if needed.
Fleet Maintenance Programs in LaSalle
Running a fleet through the LaSalle / I-80 / Illinois River 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.
LaSalle is a longer haul from most shops in the area, and that’s exactly why fleets call us. See a J&A truck out this way and need help? Just ask — we cover the distance other shops won’t.
A LaSalle breakdown call usually comes down to one of a few things — electrical faults that kill a start, air system leaks that trip a low-air warning, or cooling system failures that force a driver to pull over before the engine overheats. Whatever it is, LaSalle County fleets get the same root-cause process every time: inspect, diagnose, quote the rate, then fix it — not the other way around. No parts get swapped until we know exactly what’s wrong and why.
A roadside call in LaSalle is also a chance to catch small problems before they become out-of-service violations — worn brake linings, a cracked marker light, a slow air leak that hasn’t tripped the buzzer yet. Our certified techs flag what they see instead of just fixing what you called about. Fleets running LaSalle County regularly can set up a standing maintenance schedule so those checks happen on our timeline, not a breakdown’s, with the same upfront rate every visit and no surprise line items at the end.
