Mobile truck and trailer repairs are similar to mobile equipment repairs: Technicians travel to the truck or trailer’s location to provide timely diagnostic and roadside repair services.

Not all breakdowns need servicing at a brick-and-mortar diesel truck repair shop. Some of the most common truck repairs that can often be fixed on-site or with mobile truck repair services include:

No-start and electrical issues are common and don’t require a shop visit if the problem is isolated to a particular area. Furthermore, many brake issues can be inspected and repaired on-site, especially if the goal is to get the truck moving safely and resolve an acute issue.

Finally, with cooling, hose, tire, and fluid leak repairs, when the source is easy to reach, and the repair is contained, on-site service may be a more efficient and practical solution than an in-shop repair job.

The same can be said of trailer repairs.

Like truck repairs, trailer repairs can also often be fixed on-site.

A few trailer repair problems that can be solved with the help of a mobile repair service team include:

Most of these issues can be safely diagnosed without moving the trailer, making them strong candidates for mobile trailer repair service.

Repairs that usually require an in-shop visit

Of course, not everything can be resolved by bringing a mobile repair team to your location. Some repairs simply need to be placed on a lift and hoisted up to better resolve the issue.

The types of repairs that require an in-shop visit tend to be for common truck problems, such as engine or brake issues. A few common repairs that require an in-shop visit include:

In general, repair work that requires welding, fabrication, or heavy-lifting equipment usually warrants an in-shop visit. As such, a mobile truck doesn’t often have the capacity for these types of jobs, as these jobs require space, time, the right equipment, and the right materials for the job.

💡Note: One way to prevent the need for frequent in-shop visits is by bringing a truck in for regular, consistent preventive maintenance. Preventive maintenance helps resolve minor issues before they become major enough for an in-shop, extended visit.

Factors that determine whether a repair can be done on-site

Of course, even if a mobile repair can be completed, being aware of the factors that can affect whether an on-site job repair will be effective is key. A few factors that determine whether a repair can be completed on-site or in the field include the following:
