Truck Maintenance Without the Shop Downtime

Preventive maintenance is supposed to save money. But when PM means driving to a shop, waiting for a bay and losing half a day, it’s easy to push it back — until a small problem turns into a breakdown on I-85.

Steelcore’s mobile truck maintenance brings the PM to you. We service trucks where they’re parked — your yard, a terminal or a truck stop — while they’d be sitting anyway, nights and weekends included. The truck is ready for its next load, and nobody loses a day driving to a shop.

We handle semi truck preventive maintenance for owner-operators and fleet maintenance for companies of any size across Charlotte and about 200 miles around it. One truck or a whole fleet — the same thorough PM every time.

Truck Maintenance Services at Your Yard

Our truck PM service covers the systems that keep a truck safe, legal and earning:

Preventive Maintenance

Scheduled PM on your timeline: a full inspection, oil and filters, grease and a written record — done where the truck is parked.

  • PM service
  • Multi-point inspection
  • Oil & filters
  • Service records

Oil & Filter Changes

Engine oil, oil and fuel filters and the fuel water separator, changed at your yard. We bring the oil and take the used oil and filters with us.

  • Engine oil change
  • Oil & fuel filters
  • Fuel water separator
  • Used oil pickup

Grease & Lube

Every grease fitting on the chassis gets fresh grease: kingpins, U-joints, slack adjusters, spring pins and the fifth wheel.

  • Chassis lube
  • Kingpins & U-joints
  • Slack adjusters
  • Fifth wheel

Brakes & Air System

Linings, drums, chambers and slack adjusters checked and adjusted, and the air system checked for leaks before they turn into a write-up.

  • Brake inspection
  • Brake adjustment
  • Air leak check
  • Air dryer check

Tires & Wheel Ends

Tread depth, pressure, lug nut torque, hub oil and seals — the wheel-end checks that head off blowouts and hot hubs on the highway.

  • Tread & pressure
  • Lug nut torque
  • Hub oil & seals
  • Tire replacement

Fluids, Belts & Hoses

Coolant, DEF, power steering, transmission and differential fluids checked and topped off; belts, hoses and the air filter inspected.

  • Fluid checks & top-off
  • Coolant & DEF
  • Belts & hoses
  • Air filter

Batteries, Lights & Codes

Battery and charging system tests, every light checked, and a fault code scan to catch engine and aftertreatment problems early.

  • Battery testing
  • Charging system
  • Lights
  • Fault code scan

DOT Inspection Prep

Annual inspection or roadside checks coming up? We go through brakes, lights, tires, the air system and steering, and fix what we find.

  • Annual inspection prep
  • Out-of-service items
  • Brake & light fixes
  • Steering check

Found a problem during PM? We can usually fix it in the same visit — see mobile truck repair.

Trailers due too? We do trailer PM and repairs at the yard — see mobile trailer repair.

Broken down right now? Call (704) 441-3909 or see 24/7 emergency roadside repair. 

PM for One Truck or a Whole Fleet

For Owner-Operators

  • PM where you park: at home, at a truck stop or at your customer's lot.
  • On your time: nights, weekends or between loads — we're available 24/7.
  • Catch it early: a worn part found during PM costs far less than a breakdown on the road.
  • Records in one place: every service written down for your maintenance file.

For Fleets

  • One visit, many units: we work through your trucks at the yard or terminal while they're parked.
  • On a schedule: PM by mileage or engine hours, planned around your dispatch.
  • Unit-by-unit records: what was done on each truck, by unit number, ready for the maintenance file FMCSA requires you to keep.
  • Trucks and trailers together: we can service the trailers in the same visit.

How Mobile Truck Maintenance Works

  1. Pick a Time and Place

    Call or text where your trucks park, how many need service and when they're usually free. The last PM date or mileage helps.

  2. We Service at Your Yard

    A mechanic arrives with oil, filters, grease and common parts and works while the trucks are parked — days, nights or weekends.

  3. Records and Next PM

    You get a record of what we did, what needs attention and when the next PM is due on each truck. Any extra repair gets a price before we start.

Why Steelcore

We Come to You

Roadside, at a truck stop or at your yard. No tow and no waiting for an open bay.

Open 24/7

Nights, weekends and holidays. Breakdowns don't keep business hours — neither do we.

Trucks and Trailers, One Call

We fix the tractor and the trailer, so one breakdown doesn't mean two service companies.

Straight Answers

You hear what's wrong and what it costs before we start. No surprises on the invoice.

Frequently Asked Questions

A full inspection plus the routine work: engine oil and filters, fuel filters, chassis lube, brake and air system checks and adjustment, tires and wheel ends, fluids, belts and hoses, batteries and lights, and a fault code scan. You get a written record of what we did and found.

It depends on the engine, how the truck is used and the manufacturer’s schedule. Long-haul trucks usually go longer between oil changes than trucks in stop-and-go local work. We’ll help you set an interval by mileage or engine hours and keep each truck on it.

Yes. We plan the visit around how many units you have and when they’re parked, and work through them at your yard or terminal — nights and weekends included.

Yes. Every service is documented by unit number with the date and what was done, so it goes straight into your maintenance file. FMCSA requires motor carriers to keep inspection, repair and maintenance records for each vehicle.

Yes. We check and fix the items inspectors look at most — brakes, lights, tires, the air system and steering — before your annual inspection or a roadside check.

We take them with us and send them for recycling, so nothing is left at your yard.

A PM is priced per truck, by the service level and the oil and filters your engine takes. Repairs found during PM are quoted before we start, so there are no surprises on the invoice.

We accept Comdata, EFS and T-Chek fleet cards, major credit cards and Zelle. Net terms are available for qualified fleets.

Yes — trailer PM and repairs in the same visit: brakes, lights, air lines, tires, bearings and doors. See mobile trailer repair.
