Quick start guide
3-step success:
Your trailer maintenance roadmap
We’ve developed a comprehensive three-step process that is your roadmap to successful shop practices and trailer maintenance.
01.
Inspection & Assessment
Your truck drivers are the eyes and ears of your operation, and will almost always be responsible for conducting the vehicle checks that are necessary to maintain a preventative maintenance program.
02.
Seasonal Maintenance
The best way to determine if your trucks will need seasonal maintenance is to keep a log of their routes and anticipated weather conditions. Both extreme heat and extreme cold can cause different components and systems of a semi truck to wear out faster than usual.
03.
Mileage Maintenance
Another consideration when planning a preventative maintenance program is the distance your vehicles are traveling. Most vehicles will come with manufacturer guidelines around how far a vehicle can generally travel before a specific part will become too worn to use.
