Mechanic is doing truck wheel alignment at Absolute Repair

Wheel Alignment

It’s not uncommon for a heavy-duty diesel machine that is driven thousands of miles a week to have its steering components and suspension shift out of alignment. What many may not know, is that improperly aligned truck wheels can result in an increased 2% cost of fuel and a 20% reduction in tire life. Improper wheel alignment results in an increase in rolling resistance of the tires, essentially, the tires are dragging down the road as opposed to rolling down the road. Professional truck alignment ensures that your tires meet the road at the proper angle. At Absolute Repair, we specialize in truck wheel alignment for larger vehicles. The bigger the better actually! You can trust our certified mechanics to perform quick and reliable truck wheel alignment services.

Brake Repair

Your heavy-duty truck’s braking system is one of the most critical components of your machine. It is composed of complex elements that function together to ensure quick and reliable stopping of your vehicle and its load. Operators know that if you can’t slow down or stop you may be in immediate danger. Further to that, other drivers on the road are also at risk. At Absolute Repair, we know that stopping should always be guaranteed. We address the concerns of all models of diesel vehicles and are experienced with many different types of braking systems.

Coolant Systems Repair

Coolant Systems Repair

One of the primary functions of coolant is to regulate heat within the cylinder head and engine block of your diesel engine. The coolant system is designed to circulate a cooling medium which absorbs heat from the engine and disperses it through a heat exchanger (i.e., a radiator or cooler). In the most basic terms, coolant picks up heat and transfers it to the radiator. Coolant is also used to protect against freezing and boiling, corrosion and pitting of cylinder liners and the diesel engine block. At Absolute Repair, we advise customers on industry best practices to maintain their coolant systems and prolong the life of their heavy-duty vehicles.

DOT Inspection

DOT Inspection

The US Department of Transportation requires DOT inspections for all commercial vehicles weighing over 10,000 pounds.

At Absolute Repair, we can handle all of your driveline maintenance and repairs requirements and get you back on the road, moving in the right direction.

EGR & DPF

EGR & DPF

The EGR and DPF system in your heavy-duty truck work together as part of your emissions system to limit the output of harmful exhaust. There are federal and state vehicle emissions and fuel economy standards which are monitored and these systems are necessary to ensure your vehicle remains compliant.

Operators and fleet managers know that in order to keep their heavy-duty diesel machines running properly, ongoing and regular maintenance is required.

This is why, at Absolute Repair, we offer express lube service. We understand that your time on the road is important and want to provide service as quickly and efficiently as possible.

HVAC Systems Repair

HVAC Systems Repair

Truck drivers can spend weeks at a time in their trucks delivering products across North America and we want our customers to be as comfortable as possible while doing their critical work. It’s not uncommon for some repair shops to treat air conditioning repairs as low-priority work, but Absolute Repair is not one of those shops. Our certified technicians pride ourselves on bringing solutions to operators and fleet managers, especially when it comes to complicated HVAC system maintenance and performance. We view every problem as an opportunity to find a solution and to make our customers happy. 

Oil & Fluid

Oil & Fluid

Performance Tuning

Performance Tuning

At Absolute Repair, our technicians are trained to be able to work with you to determine the best performance options and upgrades for your specific diesel engine.

At Absolute Repair we use the most technologically advanced tuning devices to unlock your vehicle’s true potential.

Suspension Repair

Suspension Repair

The suspension system of your heavy-duty truck provides your vehicle with a cushion against the shock and impact of the road surface. Your suspension system helps your wheels to remain in even contact with the road, and smooth over potholes, rough roads, or off-road terrain so that you can brake, steer, and safely control your vehicle. A suspension system that functions correctly helps stabilize your truck, minimizes uneven tire wear, smooths the ride, and maintains the proper axle spacing and alignment. Put heavy-duty truck suspension repair in the hands of our honest and professional mechanics at Absolute Repair in Cumming IA. to save yourself time, and hassle and be sure it’s getting done right the first time.

Tire Repair

Tire Repair

Worn, deflated and flat tires can be a serious threat to getting your work done quickly and more importantly to your safety on the road. Realistically, fixing a flat or servicing an old tire is just part of life on the road. And unlike an enterprising passenger car driver, pulling out a set of tire plugs isn’t going to get the job done. You need a professional diesel mechanic to determine the best plan of action for repairing or replacing your tires. The team at Absolute Repair can help determine the best approach to either repairing or replacing your tires.

Transmission & Clutch Repair

Transmission & Clutch Repair

With so many different makes and models of diesel trucks and machines, there are varying clutch and transmission designs and systems. The one constant between these various systems though is that eventually, they all wear and break down. At Absolute Repair, we believe that it is imperative to have a preventative maintenance plan which includes transmission and clutch service and adjustments according to the manufacturer's specifications in order to keep your truck running safely and securely.
