Deep Detail for Heavy Urban Duty

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, we send visuals and options so you choose timing without losing a day.

Electrical and cooling systems suffer in traffic. 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. Less heat stress means fewer limp modes and better fuel burn.
