Drivers feel respected, your dispatch sees clear updates, and your customers get on-time deliveries.
City duty cycles are brutal: 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 live ETAs so drivers feel supported and loads stay on promise.
DPF issues, DEF dosing faults, harness fixes, smoke testing are solved with dealer-grade diagnostics to pinpoint root cause and clear derates fast.
ABS faults, brake leaks, hub seals, torque checks with documented torque so city stops stay controlled.
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 wherever the unit sits so reefer temps stay honest.
Tire swaps, bead seating, tread checks, torque verification to avoid delays on city blocks and highway merges.
We chase uptime: clear ETAs, honest estimates, photo proof. We work decisively so your load stays moving.

Expect fluid checks, brake measurements, steering play checks, battery load tests, aftertreatment health reviews, and tire wear tracking. Reports are tidy and tie to your asset IDs so budgeting is simple.
We brief drivers on warning signs like frequent regens, spongy brakes, flickering lights, hot smells, belt noise, steering pull, vibration. Early calls reduce roadside risk. It preserves delivery windows.
Every job closes with evidence: photos, torque specs, parts numbers, timestamps for audit trails. No hidden fees: clear labor, clear parts, zero upsell pressure. If we spot a future failure, we flag it with photos so you choose timing.
Your reputation matters: clean uniforms, tidy work areas, respectful communication. Drivers feel supported. Customers stay confident. This is how uptime partnerships should feel.
Specialty urban rigs and heavy vocational trucks face tight turns, weight, and constant braking. We inspect pins, bushings, torque rods, suspension hardware, driveline angles, and u-joints to stop vibration from turning into breakdown. When early warning signs appear, you get photo proof and a recommendation so you choose timing without losing a day.
Idling and heat strain power and cooling. We load-test batteries, clean terminals, validate grounds, and check voltage drop under accessory load. Cooling systems get pressure tests, belt and hose inspections, fan drive checks, and coolant quality readings. This prevents derates, protects aftertreatment, and keeps engines healthy.
