24/7 Mobile Diesel Repair
Roadside and Yard Repair Across the Chicagoland Corridors
A breakdown on I-80 at midnight or a no-start in the yard at 5 AM shouldn’t cost you a load. Our mobile diesel mechanics roll out in fully equipped service units with diagnostic tools, welding gear and common parts on board, so most repairs get done right where the truck sits.
What We Fix Roadside

For Contracted Fleets
Any commercial truck can call our dispatch. Fleet partners on a maintenance program get priority in the dispatch queue, and Tier 3 accounts receive sub-2-hour priority dispatch for emergency roadside calls (subject to availability, location, weather, and safety).
Steps:
Tell Us About Your Fleet: share your unit count, equipment mix and yard location.
Complimentary Yard Audit: we complete a 50-point yard safety audit at your location.
Review Your Proposal: you receive a custom proposal, from flat-fee PMs to a full retainer program.
Account Setup: once your Master Service Agreement and Net-30 credit application are approved, priority dispatch and full Fleet Portal access go live.

Before You Call
No. Any commercial truck can call for emergency service. Fleets on a maintenance program get priority dispatch.

The truck’s location, unit number, make and engine, and what’s happening: warning lights, fault codes, leaks or a no-start.
Most roadside failures are fixed on-site. If a repair needs a shop, such as a major engine or transmission overhaul, we’ll tell you right away.
