Fleet Maintenance Services
Preventive maintenance programs to keep your entire fleet running efficiently.
For fleet operators, downtime means lost revenue. Our fleet maintenance programs provide scheduled preventive maintenance, priority emergency service, and detailed maintenance records. We work with you to minimize downtime and maximize the life of your equipment.
For fleet operators, unplanned downtime is the most expensive line item on the budget. Every truck sitting idle costs money in lost revenue, missed deliveries, and dissatisfied customers. A structured preventive maintenance program catches small problems before they become expensive roadside breakdowns, keeps your CSA score clean, and extends the service life of your equipment. Weldon's Truck & Trailer provides comprehensive fleet maintenance services from our Kingman, AZ base, with mobile service across a 200-mile radius on I-40, US-93, and surrounding highways. Whether you manage five trucks or fifty, our ASE certified diesel mechanics work with you to build a custom PM schedule that keeps every vehicle in your fleet DOT-compliant, FMCSA-ready, and on the road earning revenue.
Detailed Fleet Maintenance Services
Our fleet maintenance programs are built around structured PM schedules tailored to your equipment, PM intervals, and operating conditions. Each preventive maintenance service includes oil change with OEM-spec lubricants, oil filter replacement, fuel filter and air filter changes, DEF filter inspection, and transmission service and differential service at manufacturer-recommended intervals. We perform oil analysis and coolant analysis sampling to detect internal engine wear before it becomes a failure. Brake adjustment and brake inspection are performed at every PM interval, including brake stroke measurement to verify DOT compliance. Tire inspection covers tread depth measurement, inflation pressure checks, and identification of irregular wear patterns. We perform DOT annual inspections, coupling device inspections, and light checks, and prepare detailed driver vehicle inspection report (DVIR) documentation and post-trip inspection records for every vehicle in your fleet. Our technicians check all lighting, safety equipment, and emissions components, and we track everything using VMRS codes for consistent maintenance reporting within your fleet management system. We work with both OEM parts and quality aftermarket parts—evaluating warranty and extended warranty coverage—to balance reliability with cost-per-mile and lifecycle cost optimization, and we integrate with your telematics platform to maximize uptime and minimize downtime by coordinating service intervals with real-time vehicle data.
What's Included
Common Fleet Maintenance Issues We Address
The most costly fleet maintenance failures we see are preventable. Skipped oil changes lead to accelerated engine wear detectable through oil analysis long before a failure occurs. Neglected brake adjustments result in out-of-adjustment brakes that fail DOT brake inspections and can trigger FMCSA compliance actions that damage your CSA score. Coolant system neglect—low coolant, degraded antifreeze, or failing water pumps—causes overheating breakdowns that strand drivers on hot Arizona highways. Missed tire inspections allow worn tires to remain in service past safe tread depths, increasing blowout risk and DOT violation exposure. Electrical issues like failing alternators and corroded connections cause no-start situations that could have been caught during a routine PM. Our preventive maintenance programs are designed to catch every one of these issues before they cost you a breakdown.
