Roadside Diagnostics or Towing to the Shop?
Paid roadside diagnostics may be requested for trucks in the Myrtle Beach area. Availability depends on the truck’s location, technician schedule and whether the site is safe for diagnostic work. A roadside visit is primarily a diagnostic service and does not guarantee that the complete repair can be performed at the breakdown location.
When parts, programming, shop equipment or extended testing are required, towing the truck to our Conway shop can be faster and more economical than waiting roadside. We explain the practical options before dispatch so the customer can choose the best next step.
When you call, please provide the truck make, model and year, current location, symptoms, warning messages, available fault codes and whether the truck can be moved safely.
Truck Brands We Service
We provide priority diagnostic support for Freightliner, Volvo, Peterbilt and Kenworth, and we work on other heavy-duty truck makes depending on the engine, system configuration and required procedure.
Our Diagnostic Process
- Describe the concern. Tell us what the truck is doing, when it occurs and what warnings or codes are present.
- Test connected systems. We use software data, guided procedures and direct measurements to narrow the failure path.
- Confirm the repair direction. We explain the findings and recommended work before completing additional repairs.
- Repair and verify. After approved work is completed, we check the affected system for correct operation.
Frequently Asked Questions
Is there a My Truck Repair Shop in Myrtle Beach?
Our physical repair facility is at 3236 US-701 Hwy in Conway, South Carolina. We serve customers from Myrtle Beach and surrounding Grand Strand communities, but we do not claim a separate shop in Myrtle Beach.
Do you offer roadside truck repair in Myrtle Beach?
Paid roadside diagnostics may be available by request. Availability depends on location, technician scheduling and safe working conditions. A roadside diagnostic visit does not guarantee that the complete repair can be finished at the breakdown location.
Should I request roadside diagnostics or tow the truck to the shop?
For many electrical, emissions, software and mechanical concerns, towing to our Conway shop can be faster and more economical because parts, equipment and a full work area are available. Call with the location and symptoms so we can discuss the practical options.
Can you diagnose DEF, DPF, EGR, SCR faults and truck derates?
Yes. We test connected aftertreatment components, sensors, wiring, operating data and control-system behavior to identify the underlying cause. Clearing a code alone does not repair the problem.
Which truck brands do you service?
Our priority brands are Freightliner, Volvo, Peterbilt and Kenworth. We can also service other heavy-duty makes depending on the truck, engine, system and required procedure.
