Mobile Peterbilt Truck Repair in Gary, IN

High mileage, heavy loads, long operating hours, and demanding road conditions can put significant stress on a Peterbilt’s mechanical and electrical systems. When something starts acting differently, identifying the problem early can help prevent a smaller issue from becoming a complete roadside failure.

Diesel Rescue 24/7 provides mobile Peterbilt diagnostics and repair for problems including:

• Engine performance and power loss
• Check-engine lights and fault codes
• No-start and starting problems
• Battery and charging system issues
• Wiring and electrical faults
• Air brake problems and air leaks
• Overheating and cooling system problems
• EGR and DPF issues
• Regeneration failures and derates
• Transmission and clutch problems
• Driveline and axle issues
• Suspension problems
• HVAC system problems
• Oil, coolant, and other fluid leaks

Our mechanics troubleshoot the affected systems where the truck is stopped and determine what needs to be repaired.

Peterbilt 579, 567, 389 & 337 Repair

Diesel Rescue 24/7 services Peterbilt commercial trucks used across highway, vocational, and medium-duty applications, including popular models such as the 579, 567, 389, and 337.

Peterbilt 579 trucks are commonly used for highway and long-haul freight, while the 567 serves demanding vocational applications. The 389 remains a familiar choice in heavy-duty trucking, and the 337 is used across a variety of medium-duty commercial applications.

Because operating conditions and truck configurations vary, our mechanics diagnose the specific symptoms your Peterbilt is experiencing rather than treating every breakdown the same way.

Peterbilt Engine & Fault Code Diagnostics

A check-engine light can be caused by anything from an electrical or sensor fault to a problem involving engine performance, fuel delivery, or emissions equipment.

The diagnostic code provides a starting point, but additional troubleshooting may be necessary before the actual failed component can be identified.

Diesel Rescue 24/7 provides mobile Peterbilt diagnostics to retrieve fault information and investigate the systems involved. This approach is particularly useful when the truck has lost power, developed an intermittent problem, or gone into derate without an obvious mechanical failure.

Peterbilt DPF, EGR & Derate Problems

DPF and EGR problems can lead to warning lights, unsuccessful regenerations, reduced engine performance, and derates that eventually prevent a Peterbilt from continuing its route normally.

The cause may involve the DPF, EGR components, sensors, wiring, exhaust-system faults, or other conditions affecting the emissions system.

Our mechanics work to determine why the fault occurred rather than simply clearing the code. If the underlying problem can be appropriately addressed at the truck’s location, we’ll perform the on-site repair when possible.

Peterbilt Brake & Drivetrain Repair

Peterbilt trucks operating under heavy loads depend on their braking and drivetrain systems mile after mile. Changes in either system should be taken seriously, particularly when the truck begins vibrating, shifting poorly, losing air pressure, or making unusual noises.

Our mobile mechanics can troubleshoot air brake, transmission, clutch, driveshaft, U-joint, axle, and related problems directly at your Peterbilt’s location.

Some failures can be repaired roadside, while major internal transmission, differential, or other component failures may require more extensive shop-level work. In those cases, mobile diagnostics can still help determine what failed and the appropriate next step.
