Mack Truck Repair in West Palm Beach, FL

Mack trucks are the bulldogs of the trucking industry — built tough for the hardest jobs in construction, refuse, and heavy haul. At Albert’s Road Service, we work on Macks regularly across South Florida, from Granite dump trucks hauling fill in Palm Beach County to Anthem highway tractors running I-95 freight lanes. We carry factory-level diagnostic tools for Mack’s Volvo-based powertrain and understand the specific systems that make these trucks unique.

Models We Service

Anthem (Class 8 Highway)

Mack’s flagship highway tractor built on a modern platform with the MP8 engine and mDRIVE automated transmission. The Anthem is gaining popularity in Florida’s freight corridors for its fuel efficiency and driver comfort. We service the complete integrated powertrain, aftertreatment system, and Mack’s Guardian electronic architecture.

Pinnacle (Class 8 Highway / Vocational)

The Pinnacle served as Mack’s primary highway tractor before the Anthem and remains widely used. Available with MP7 or MP8 engines and mDRIVE or manual transmissions, these trucks log high miles in Florida and require regular aftertreatment service, clutch maintenance, and cooling system work.

Granite (Vocational / Severe Duty)

The workhorse of Mack’s lineup and arguably the most common Mack in South Florida. The Granite dominates in dump truck, mixer, refuse, and heavy construction applications. Florida’s year-round construction season keeps these trucks busy, and we handle the MP7/MP8 engine service, mDRIVE and Allison transmission work, PTO system diagnostics, and the heavy-duty suspension repairs that vocational duty demands.

LR (Refuse / Low-Ride)

Mack’s dedicated refuse chassis is a frequent sight in South Florida’s waste management fleets. The LR’s low-entry cab and specialized hydraulic systems require specific knowledge. We service the MP7 engine, Allison transmission, and the hydraulic body systems that keep refuse operations running.

TerraPro / MD Series

The TerraPro serves concrete pumper and heavy vocational roles, while the MD Series covers Mack’s medium-duty segment. We service both platforms including their Cummins engine options and Allison transmissions.

Engine Platforms

Mack trucks run Volvo-based engines rebranded for the Mack lineup — the MP8 (12.8L, essentially a Volvo D13) for heavy-duty applications and the MP7 (10.8L, based on the Volvo D11) for medium and vocational use. Both are inline-6 diesels with common-rail fuel injection and variable geometry turbochargers. The mDRIVE automated manual transmission is standard on highway models, while vocational trucks often run Allison automatics. We use Volvo VCADS Pro and VOCOM II to diagnose Mack engines and transmissions — the same factory tools Mack dealerships rely on — giving us full access to fault codes, live data, forced regenerations, and ECM programming.

Common Mack Problems We Fix

MP8 aftertreatment derates — Just like its Volvo D13 sibling, the MP8’s integrated aftertreatment system develops DEF dosing failures, NOx sensor faults, and DPF soot overload conditions. Florida’s heat degrades DEF quality and accelerates crystallization in the dosing unit. We run complete aftertreatment diagnostics rather than guessing at which component failed.

mDRIVE clutch wear and shift faults — The mDRIVE automated transmission is reliable but develops clutch wear over time, especially in vocational applications with frequent starts and stops. Granite dump trucks in particular see accelerated clutch wear due to heavy loads and low-speed maneuvering. We read clutch wear data, perform adaptation resets, and diagnose shift quality complaints on-site.

EGR valve and cooler failures — The MP7 and MP8 EGR systems develop stuck valves and internal cooler leaks. An EGR cooler leak pushes coolant into the intake, causing white smoke, coolant loss, and potential cylinder damage. Florida’s thermal cycling between hot daytime operation and overnight cooling stresses EGR cooler joints.

Cooling system overheating — Mack trucks in vocational service — especially Granites and LRs that idle extensively — overheat frequently in South Florida summers. Failed fan clutches, clogged radiators packed with construction debris, and deteriorated coolant are regular issues. We diagnose the root cause and repair it on-site.

Electrical and Guardian system faults — Mack’s Guardian electronic architecture manages powertrain, chassis, and body functions. Corroded connectors and water intrusion in Florida’s rainy conditions cause intermittent dashboard warnings, HVAC failures, and communication faults between modules.

Our Mack Diagnostic Capabilities

We carry VCADS Pro and VOCOM II — the same factory diagnostic platforms used by Mack dealerships — and can perform:

• Full MP7/MP8 engine fault code reading and live data monitoring
• Forced DPF regenerations and aftertreatment system verification
• mDRIVE clutch calibration, wear measurement, and adaptation resets
• Injector programming and cylinder balance tests
• Allison transmission diagnostics via Allison DOC
• ABS and stability control diagnostics
• ECM parameter changes and Guardian system configuration
• PTO and body builder module diagnostics
