About Our Mobile Truck Repair Service
Mobile truck repair brings a diesel mechanic, diagnostic equipment, tools, and commonly needed supplies to an on-highway truck or trailer. It may be appropriate for a roadside mechanical failure, a truck that cannot reach the shop, a yard repair, or qualifying scheduled fleet work.
Whether a repair can be completed on-site depends on the failure, parts availability, component access, required tooling, and the safety of the location. Work requiring major disassembly, lifting equipment, structural repair, or controlled shop conditions may need to be completed at our 36-bay Tyler facility.
Commercial Truck Problems We Address On-Site
Our mobile service trucks are equipped for a range of on-highway diagnostic and repair work:
- Computerized diagnostics: Fault-code retrieval and testing for supported engine, ABS, electrical, sensor, and control-system concerns.
- Electrical repairs: Wiring problems, starting and charging concerns, sensors, connections, trailer connectors, marker lamps, and lighting issues.
- Air-brake repairs: Brake inspections, brake chambers, slack adjusters, air leaks, and related components when field conditions allow.
- Air-system repairs: Air lines, fittings, glad hands, air dryers, and accessible pneumatic components.
- Cooling-system repairs: Coolant leaks, damaged hoses, overheating diagnosis, coolant service, and accessible cooling components.
- Fuel and drivability concerns: Fuel-filter replacement, basic fuel-system diagnosis, injector-related testing, and supported DEF-system concerns.
- Suspension repairs: Air bags, shocks, leaf-spring concerns, and related components when the work can be performed safely on-site.
- Belts and hoses: Serpentine belts, coolant hoses, accessory-drive components, and accessible hose failures.
- Hydraulic hose service: On-site hose fabrication or replacement for supported hydraulic-equipped trucks.
- Oil and fluid service: Emergency fluid correction, oil service, and fluid top-offs when appropriate.
- Minor engine repairs: Accessible engine repairs that do not require major teardown or shop equipment.
- Tire assessment: Evaluation of tire concerns and guidance on the appropriate next step.
A mobile diagnosis does not mean every repair can be completed during the same visit. Application-specific parts may need to be sourced from the shop or a supplier.
When In-Shop Repair Is the Better Option
Some work is better suited to the Hex 6 facility, including:
- Major engine teardown or rebuilding
- Full transmission replacement
- Complex structural repair
- Work requiring extensive lifting or specialized shop equipment
- Repairs that cannot be completed safely at the breakdown location
- Jobs requiring assemblies that are not available on the mobile truck
If shop service is required, the technician can explain why the work is not suitable for field conditions and discuss the next step.
