Oswego

Oswego’s growth has brought more fleet operators into Kendall County. J&A Fleet provides the roadside and maintenance coverage this area needs.

J&A Fleet Maintenance provides mobile diesel repair and emergency roadside service in Oswego and the surrounding Kendall County. When your truck can’t move, we come to you — roadside, yard, or dock — with a quoted rate and a certified tech.

Oswego’s growth means more fleets running through Yorkville and out toward Plainfield and Aurora — all inside J&A’s coverage, dispatched from our New Lenox shop and mobile crews.

Shop Work — New Lenox and mobile service

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

Fleet Maintenance Programs in Oswego

Running a fleet through the Oswego / Route 34 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.

We’re not just turning wrenches in Oswego — we’re a fleet partner. Ask about the mobile maintenance program if your units run through Kendall County regularly; it’s built to cut downtime, not just generate another invoice.

Most calls into our Oswego coverage area break down into a handful of repeat problems: a dead alternator or a parasitic draw that leaves a truck no-start at a dock, a low-air buzzer tripping on the shoulder, or a coolant leak that turns into an overheat call in stop-and-go traffic. Whatever brings a Kendall County fleet to a stop, the process is the same — diagnose to the root, quote the rate, fix it once. Our mobile techs carry the diagnostic tools and common parts to close out most of these calls on the first visit, instead of sending a driver back out for a second trip.

Whether it’s an emergency call or a routine visit, a stop in Oswego is also a chance to catch what a driver hasn’t noticed yet — worn linings, a slow air leak, a marker light that’s about to fail an inspection. Our techs flag it instead of just fixing what you called about. For fleets running Kendall County on a repeat basis, a standing maintenance schedule usually costs less over a year than a string of one-off roadside calls billed separately, one truck at a time.
