Preventive Maintenance Is Cheaper Than Breakdowns

A roadside breakdown means towing, lost loads and a rushed repair. Preventive maintenance (PM) finds worn belts, leaking hoses, low brake linings and weak batteries during a planned visit, when fixing them is quick and cheap. Emergency Roadside Truck & Trailer Repair performs PM service at our Phoenix shop and at your yard.

What Our PM Service Includes

  • Engine oil and filter change; fuel and air filters as scheduled.
  • Coolant, DEF, transmission and differential fluid checks.
  • Chassis lubrication and fifth-wheel greasing.
  • Brake inspection and adjustment check.
  • Belts, hoses and cooling system inspection.
  • Battery and charging system test.
  • Tires, suspension, steering and lights.
  • Fault-code scan and aftertreatment check.

Adjusting Maintenance for Arizona

Heat, dust and long idle times are hard on trucks. Consider shorter air-filter intervals on dusty routes, a cooling system check before summer, and battery testing in spring. Our technicians will recommend a schedule based on how your trucks actually run.

PM for Fleets

If you run several trucks, a fleet maintenance program schedules PMs and DOT inspections together, so units come off the road as little as possible.

The Cost of Skipping PM

A $20 belt or a worn hose can leave a loaded truck on the shoulder of I-10, adding a tow, a missed delivery and an emergency repair bill. Low brake linings can lead to damaged drums, and ignored air leaks can become out-of-service violations at inspection. Preventive maintenance turns those surprises into planned, lower-cost repairs.

After Each PM

We let you know what we serviced, what we found and what should be planned for the next visit, so you can budget repairs instead of reacting to breakdowns.
