Diesel Truck Service Across Teton County, Wyoming

Diesel trucks are the backbone of Teton County's working economy. Ranchers run F-350s and RAM 3500s hauling cattle trailers, feed, and equipment across vast properties. Contractors drive Silverado 2500s loaded with tools and materials to job sites throughout the valley. Snowplow operators depend on diesel power to keep roads and parking lots clear during Jackson Hole's long winters. These trucks are not lifestyle accessories — they are essential tools that must perform in conditions that would sideline lesser vehicles.

At The Garage by Detail Driven, we provide the specialized diesel service that Teton County's working trucks demand. Our diesel mechanics have hands-on experience with all three major diesel engine families — Ford Powerstroke, GM Duramax, and RAM Cummins — spanning multiple generations and configurations. We invest in diesel-specific diagnostic tools, maintain relationships with diesel parts suppliers for fast component availability, and stay current on the technical service bulletins that affect these constantly evolving powertrains.

We serve diesel truck owners throughout Teton County, from Jackson and Wilson to Kelly, Moran, and the ranch properties along the Gros Ventre and Buffalo Valley roads. If your diesel truck needs work, we are your nearest qualified diesel shop.

Fuel Injection System Service

Modern diesel fuel injectors operate at pressures exceeding 30,000 PSI in common rail systems. At these extreme pressures, even microscopic contamination or wear can cause rough running, excessive smoke, power loss, and poor fuel economy. We diagnose injector problems using contribution balance testing and injector buzz testing, then repair or replace individual injectors as needed. We also service high-pressure fuel pumps, fuel rails, and fuel filtration systems. For Teton County trucks that sit idle for extended periods or use fuel stored in ranch tanks, we pay special attention to fuel quality and water contamination.

Turbocharger Diagnosis and Repair

Every modern diesel truck has at least one turbocharger, and many have variable geometry turbos (VGT) or compound turbo systems. At Jackson Hole's 6,200-foot elevation, turbochargers work significantly harder to maintain performance because the ambient air is thinner. This increased workload accelerates bearing wear, vane sticking in VGT units, and actuator failure. We diagnose turbo issues using boost pressure testing, exhaust back-pressure measurement, and visual inspection of the compressor and turbine wheels. Repairs range from actuator replacement to complete turbo rebuild or replacement.

Diesel Exhaust Fluid (DEF) System Maintenance

All diesel trucks from 2010 and newer use Selective Catalytic Reduction (SCR) with DEF to meet emissions standards. DEF system problems — including quality sensor failure, injector clogging, and SCR catalyst degradation — can put your truck into reduced power mode or prevent it from starting altogether. We diagnose and repair DEF injectors, NOx sensors, DEF quality sensors, SCR catalysts, and DEF tank heaters. In Teton County's extreme cold, DEF can freeze in the tank and lines, and the heating system must function correctly to prevent this.

Glow Plug and Cold Start Systems

Starting a diesel engine at negative 20 degrees requires a fully functional glow plug system. Weak or failed glow plugs mean hard starting, extended cranking, white exhaust smoke, and rough running until the engine warms up. We test individual glow plugs, glow plug controllers, and intake air heaters to ensure reliable cold starting through Teton County winters. We also recommend block heater use and proper cold-weather diesel fuel treatment.

Diesel Oil Service

Diesel engines require specific oil formulations that handle higher soot loading, greater thermal stress, and the presence of diesel particulate filter (DPF) regeneration byproducts. We use CK-4 rated diesel oils in the correct viscosity for your engine and our climate. Oil change intervals for diesel trucks in Teton County should follow the severe-service schedule — typically 7,500 miles or six months rather than the normal 10,000 to 15,000-mile intervals.

Each diesel engine family has distinct engineering characteristics, common failure points, and service requirements. We maintain expertise across all three:

Ford Powerstroke

From the 7.3L that refuses to die to the current 6.7L with its sophisticated emissions controls, we service all Powerstroke generations. Common issues we address include 6.0L head gasket and EGR cooler failures, 6.4L turbo and DPF problems, and 6.7L CP4 fuel pump concerns. The 6.7L Powerstroke is particularly common in Teton County and we stock common maintenance items for quick turnaround.

GM Duramax

The Duramax diesel has powered Chevrolet Silverado and GMC Sierra HD trucks since 2001. We service all generations from the LB7 through the current L5P. Known issues include LB7 injector failure, LLY overheating, LBZ and LMM fuel system concerns, and L5P emissions component maintenance. We perform Allison transmission service alongside Duramax engine work since these powertrains function as an integrated system.

RAM Cummins

The Cummins 5.9L and 6.7L inline-six engines are legendary for longevity, but they still need proper maintenance and develop issues at high mileage. We handle 5.9L VP44 injection pump replacement, 6.7L common rail injector service, turbo actuator repair, and the emissions system components that can put a Cummins into limp mode. The 68RFE automatic transmission paired with the Cummins also requires specific service attention.

Teton County's ranching operations rely on diesel trucks for daily work — hauling livestock trailers, feeding cattle in remote pastures, plowing snow from ranch roads, and towing equipment. These trucks accumulate hard miles in harsh conditions: dusty summer roads, freezing winter mornings, heavy loads, and extended idle time while running PTO-driven equipment.

We offer fleet maintenance programs for ranch and business operations that run multiple diesel trucks. This includes scheduled service intervals, maintenance record keeping, priority scheduling for breakdowns, and proactive inspection to catch developing problems before they cause field failures. A diesel truck that breaks down in a remote pasture during calving season is not just an inconvenience — it can put animals at risk.

For contractors operating diesel trucks and equipment throughout Teton County, we understand that downtime costs money. We stock common diesel maintenance items — filters, fluids, belts, glow plugs — and have supplier relationships that allow us to source most diesel-specific parts within one to two business days. When possible, we schedule repairs to minimize the time your truck is out of service.

We also advise on cold-weather diesel fuel management. In Teton County, switching to winter-blend diesel fuel by November is essential to prevent fuel gelling. We recommend fuel additives with anti-gel properties and can install or service fuel line heaters and tank heaters for trucks that are parked outside overnight.

The Garage by Detail Driven is centrally located at 940 W Broadway, Jackson, WY 83001, making us accessible from anywhere in Teton County. We serve diesel truck owners from Jackson, Wilson, Teton Village, Kelly, Moran, and the surrounding ranch communities.

Hours: Monday through Friday, 8:00 AM to 5:00 PM.

If your diesel truck is down and cannot be driven to our shop, several towing companies in Teton County can transport heavy-duty trucks. Call us and we can help coordinate. For ranchers in remote locations, we understand the logistics of getting a heavy truck to town and will work with you on scheduling to make the trip count.
