Urban miles are tough: dense traffic, short runs, ELD timers. We build maintenance plans around actual city stress. That means watching brakes, cooling, electrical, aftertreatment, and tires closely. Preventing failure beats paying for a tow.
Jump starts, air leaks, coolant loss, fuel delivery, lockouts, light failures with safe staging and progress pings so drivers feel supported and windows hold.
Aftertreatment codes, forced regens, sensor swaps, wiring repairs, ECM scans are solved with dealer-grade diagnostics to avoid parts darts and return the truck to full power.
ABS faults, brake leaks, hub seals, torque checks with documented torque so dense-traffic braking stays tight.
Oil and filter service, fluid top-offs, multi-point inspections, DOT pre-checks tuned to stop-and-go patterns to limit sudden failures.
Electrical rehab, cooling fixes, reefer triage handled on the curb, at the dock, or in the yard so reefer temps stay honest.
Mobile mounting, balancing, rotations, torque checks, roadside tire replacement to avoid delays on potholes, curbs, and expressway ramps.
