Good diagnostics take years to refine through hands on experience.

With over 20 years in the industry, we make sure we’re doing everything we can to diagnose trucks as accurately and efficiently as possible.

Good diagnostics help us get repairs done quicker and get our customers back up and running faster.

Less guessing. Less downtime. Back to work.

When a truck is responsible for hauling a big part of your product, having it sit down for weeks isn’t an option. 🔧

Our customer called us with a truck in their fleet that needed some major suspension work done in a timely manner.

This truck had significant suspension damage, including broken leaf springs. On top of that, it’s built with an out of the norm suspension setup, so finding the correct parts wasn’t just a call in.

We sourced the parts needed, got the repair scheduled, dispatched out, and got to work.

Repairs are complete and this truck is now safely back on the road doing the job it was built to do.

We understand how important these trucks are to the businesses that depend on them every day. Whether it’s a major repair or something smaller, our goal is to get it scheduled, repaired correctly, and back to work as efficiently as possible.

Have a truck down or a repair you’ve been putting off? Give us a call and let’s get you on the schedule. 🧰

We had this customer in for a preventative maintenance follow up.

We notated that the engine oil pan looks to be leaking oil. The customer wanted to get this repaired ASAP.

We were able to respond out and remove the lower oil pan, reseal it and get this customer back on their way right before school!!

This bus is headed out to a school near you for a mobile library. Pretty neat for our children around the St. Louis area to be able to experience such a nice truck revolved around reading and learning.

We started this Monday morning off with a diagnostics job.

The customer contacted us saying they were unhappy with the prior provider. Saying after a few hours of diagnostics they couldn’t come up with a solution.

We were hopeful to just help this customer out and give them a solid answer.

Upon arrival, customers complaint that this truck was a crank no start.

We connected with our diagnostic laptop to try and establish communications to the engine. We usually start out with this to monitor active engine fault codes that might have any indication why this truck isn’t starting.

Unable to connect with ECM with our Detroit software, we tried a generic software version trying to establish any communication with the ECM. We were unsuccessful. We started to dive digger into why there was not any communication across the ECM, but only the ABS module and transmission module.

We started out at the battery box we found a clean power in the fuse. The fuse checked OK and the clean power was supplying the ECM with battery voltage. We remove the ECM connector going into the ECM. We established that we have a good clean power battery voltage along with ignition voltage. We checked the grounds and found both grounds to be OK. We reconnected the ECM connector and removed the engine sensor harness connector we tested all of the pins coming out of the ECM to find there is no power coming out of the ECM.

This indicates that the ECM has malfunctioned and will need to be replaced.

Even though this is something that we cannot finish up for this customer, we try to help them and guide them through this repair usually with trucks this old reprogramming ECM’s like to have the unit available in case there is any issues program in the ECM to that truck. The dealership is likely the way to go in this scenario.

Even though we can’t complete this job through its entirety, we like the point customers in the right direction.

When your trucks work overnight, waiting days for a repair isn’t really an option.

Our customer called us about one of their trucks running rough and dying under acceleration. This crew does a ton of overnight highway work, so getting their trucks back up and running in a timely manner is important.

We worked directly with their shop on this one. We dispatched out, ran diagnostics, and found a bad injector.

We sourced OEM parts and were able to be back out the following morning to complete the repair.

After replacing the injector, the truck was running better but was still low on power. Instead of calling it good and sending it back to work, we continued diagnosing and found additional repairs that needed to be addressed.

We communicated everything we found directly with their shop, worked together to get the final repairs completed, and this truck is officially back on the road and back to work.

This is a big part of what we do. We can work directly with your shop and your mechanics to help diagnose problems, complete repairs, or simply provide the extra help needed to keep your fleet moving.

Downtime costs money. Our goal is to diagnose it correctly, communicate what we find, and get the repair completed as efficiently as possible. 🔧

Sometimes you know what needs repaired, you just need the help getting it done. 🔧

Our customer called needing a blower box assembly replaced. They had already diagnosed the truck in their own shop, but needed some help getting the repair completed in a timely manner.

We got them scheduled in, went out on site, and completed the planned repair.

While we were there, we continued inspecting the truck and found another issue related to the original problem that also needs to be addressed.

We finished the repairs we were scheduled for and made sure our customer knew exactly what else we found and what repairs will be needed to get this truck back to running its best again.

Not every call starts with us diagnosing the problem. Sometimes you already know what you need and just need an extra set of experienced hands to get the work done.

Either way, our goal stays the same. Get the repairs done right, keep our customers informed, and help keep their trucks on the road.
