FAQs

How Long Does It Take To Run Diagnostics On A Truck?

Running diagnostics on a truck usually takes between 30 minutes to an hour. The time depends on the type of issue, the truck's make and model, and the tools used. More complex electrical or engine problems may require deeper testing and take longer.

How Do I Decide To Replace Or Repair?

You should compare the cost of repairs against the truck’s value and future reliability. If repairs are frequent or exceed half the truck’s value, replacement might be the smarter option. Always consider downtime, safety, and long-term operating costs before deciding.

What Is A Routine Maintenance Check?

A routine maintenance check includes inspecting fluid levels, filters, belts, hoses, tires, and key engine components. Technicians also look for signs of wear, leaks, or early damage. Regular checks help catch small issues before they turn into costly repairs or cause breakdowns.

How Do I Know If My Trailer Spindle Is Bent?

A bent trailer spindle often causes uneven tire wear, wheel wobble, or difficulty aligning the axle. You might also notice vibrations while towing. If you suspect an issue, a technician can inspect it using alignment tools or by removing the hub for a closer look.

If you’re looking for a great diesel shop in Louisiana or are just traveling through look no further. I was on my way to Florida from Texas and had some engine troubles they figured out my problem very quickly and were able to get me back on the road the very next day.

These people work pleasant, professional, and willing to help. They've been there for quite some time many years and they were very busy which tells me that they must do good work because there were trucks outside waiting to get in and get worked on.
