How Much Can One Failed Part Cost You? More Than You Think.

Commercial trucks keep the world moving — but it only takes one failed component to bring everything to a stop. That means late deliveries, roadside repairs, and lost revenue.

Knowing which parts are most likely to cause breakdowns — and how to stay ahead of them — helps keep your fleet running strong.

Here are 7 high-risk components to watch out for:

1. Engine Cooling System (Radiator, Water Pump, Hoses)
Overheating is a top cause of engine failure. A small leak or faulty pump can shut things down fast.
✅Check coolant levels and hoses often.

2. Transmission System
A slipping or overheated transmission can stop power delivery — and that means towing tons of cargo.
✅Monitor shifting, check fluid, and follow service intervals.

3. Brake System
Brake issues aren’t just costly — they’re dangerous. Loss of pressure or worn pads can take a vehicle off the road.
✅Inspect lines, compressors, and pads regularly.

4. Fuel System (Filters, Injectors, Pumps)
Clogs or pump failures can starve your engine — especially in diesel trucks.
✅Change filters often and keep an eye on fuel pressure.

5. Battery & Electrical System
Modern trucks rely on electronics. A dead battery or weak alternator can cut off ignition and controls.
✅Test batteries twice a year and check alternator performance.

6. Tires & Wheel Bearings
Blowouts and seized bearings can lead to sudden stops — or worse, roadside emergencies.
✅Keep tires inflated, inspect tread, and listen for unusual noises.

7. Suspension & Steering Components
Worn parts here affect handling and can even take your truck out of compliance.
✅Add steering and suspension checks to your routine maintenance.

Keep Your Fleet Moving
Breakdowns aren’t just mechanical — they disrupt business. Staying ahead of these high-risk components helps avoid surprises and keeps your operation on schedule
