Mack Truck Repair and Maintenance

Mack is known for building extremely tough trucks. They’re generally regarded as being some of the most durable trucks on the market. They can haul a hundred thousand pounds across a continent with little to no difficulty whatsoever, all whilst keeping their driver safe and comfortable. Although Mack certainly builds impressive trucks, they are not immune to the need for maintenance. Just like other trucks, they’ll break down if not maintained properly, meaning preventive maintenance is of the utmost importance. Whether it be simple maintenance or large-scale engine repair, you can rest assured knowing JE-CO has your back. 

Common Mack Maintenance and Repair Needs


Tires are perhaps one of the most important components to maintain on a regular basis. They are the only part of your vehicle that touches the ground, meaning they are the component that must always be in good shape. Over time your tires will experience tread wear and although this is normal, uneven tread wear is not. Uneven tread wear occurs when you don’t rotate your tires on a routine basis. By rotating your tires, you are lengthening the lifespan of your tires and saving yourself money. 

Brake Systems

Hauling extremely heavy loads is only safe if you have enough braking power to bring that load to a stop. Here at JE-CO Equipment, we’re brake system experts. We work on everything from air brakes to fluid-based brakes. Whether you need a complete air-line inspection or new brake calipers, JE-CO has your back.

These guys were great! They are open 7 days/week, which is why I found them. They diagnosed and rebuilt the power divider on my 2000 Pete. G and the staff were excellent with their communication. They will be my first call if I ever need work done in the Denver area. Thanks Jeco!
