Work Truck Repair and Maintenance for Contractors

The parts that carry and stop the weight. A bed full of tile or a ladder rack with a toolbox changes how the truck rides every mile, even when you are not towing.

• Rear brakes: they do more work when the bed is loaded.
• Tires: passenger-rated tires on a loaded truck run hot and wear fast.
• Leaf springs and shocks: sagging or bouncing means they are tired.
• Ball joints and tie rods: heavy front ends and job-site ruts loosen them.
• Wheel bearings: a growl that rises with speed is common on high-mileage work pickups.

Our pickup trucks page covers body-style details, and suspension, shocks, and struts explains how we test ride control.

Match the load index and load range to what the truck actually carries. Many work pickups need LT (light truck) tires rather than P-metric passenger tires. The door placard lists the minimum, and your real payload may call for more.

Set pressure for the load you carry. An underinflated LT tire under weight builds heat quickly. See new tires and brands for how we pick fitment.

Planning is the fastest repair. Tell us what trade you work in, what the truck carries, and which days it can be down. We look for parts availability before the truck is apart, so a missing part does not park you for two days.

Short work like oil, tires, and a brake inspection is often done while you wait if the bay is open. Bigger jobs go better as a drop-off early in the day. If you run several trucks, the fleet vehicles page explains how we track each unit.

Yes, for routine maintenance and many repairs. Diesel pickups need oil that meets the engine maker's diesel spec, fuel filter changes, and a look at the fuel-water separator. Gas trucks need the usual spark plug, coil, and cooling work at higher mileage.

Some diesel emissions repairs need specialist equipment. If your truck needs work we are not set up for, we tell you before charging for guesses. Read more on diesel maintenance.

Yes. Buyers of used work trucks look for records, even tread wear, and a clean underside. A stack of invoices with dates and mileage tells the next owner the truck was cared for, not just driven hard.

We record mileage on every invoice and note what we measured, so your paper trail builds itself. Keep those invoices in the glove box or a folder. If you are buying another truck, a pre-purchase inspection checks the frame, hitch, and tire load range before you sign.

A two-minute walkaround at the start of the day catches most problems before they cost a job. It needs no tools beyond a tire gauge, and anyone on the crew can do it.

Morning checklist for a work pickup:

1. Walk around and look at every tire, including inner duals if you run them.
2. Check tire pressure weekly, and any time a tire looks low.
3. Look under the truck for fresh drips where it was parked overnight.
4. Confirm the load is secured and the rack or toolbox is tight to its mounts.
5. Test brake lights, turn signals, and any amber work lights.
6. Listen at startup for new squeals, knocks, or a slow crank.
7. Note warning lights on the dash before pulling out.

Write down anything new and send us the note with your service request. A driver's description of when a noise started saves diagnostic time. A good digital vehicle inspection at each visit backs up what the crew sees.

They add weight that never comes off. A steel ladder rack, a crossover toolbox, and a full set of hand tools can take a real bite out of the payload before you load a single bag of material. The truck carries that load on every commute, not only on job days.

What that means in practice:

• Tire pressure: set it for the loaded condition on the placard, since the truck is never empty.
• Rear shocks: they work harder and fade sooner than on an unloaded pickup.
• Brake balance: rear pads and shoes can wear faster than the front on some trucks.
• Wiring: added work lights and inverters tap into the electrical system, and a poor splice can drain the battery overnight.

Tell us what is bolted to the truck when you book. We weigh that in when we check battery and charging health and suggest tire load ranges.

Plan for the predictable wear items and keep a reserve for the unpredictable ones. On a work truck, tires, brakes, and fluids come around on a schedule tied to miles and load. Front-end parts, bearings, and electrical faults show up less predictably.

A simple approach many owners use: log every invoice by date and mileage, add up the last twelve months, and set aside a similar amount for the next twelve, plus a cushion if the truck is getting older. Book bigger jobs during your slower weeks when a day off the road hurts less. We can list what is likely due over the next few visits so the numbers are on paper before the busy season starts.
