Consider the miles you spend on I-78, Route 22 and the Northeast Extension each and every week. Add stop-and-go warehouse traffic as well as cold winters and road salt as parts wear out faster than you’d guess. Below, you will see what good maintenance actually includes how often you need one and why.
Why Preventative Maintenance Actually Important for Your Trucks?
When you have preventative maintenance, you’re just doing things when they are small enough that they won’t come out on the road and cause a problem. That schedule is based on mileage or calendar months or engine hours – whichever it is, that is the one that gets to you first. It’s also the law, as mandated by the Federal Motor Carrier Safety Administration, which must be performed during regular commercial vehicle maintenance.
You have to inspect as well as repair and maintain all vehicles that you control and to keep records. A written fleet preventive maintenance plan covers that rule and helps you prevent costly out of service orders at inspections. Honestly, the fleets that skip maintenance are usually the ones calling for a tow truck in January.
What is Included in a Truck and Trailer Preventative Maintenance Service?
A comprehensive preventative maintenance inspection checks all major systems and each of them is important to ensure safe heavy vehicle maintenance. A good technician will work from a written checklist so there is no chance of anything being overlooked and a report will be provided. This is the typical Checklist when you arrive with a tractor and trailer in the bay.
Engine, Fluids and Filters
Your tech changes the oil and filters then tops off coolant as well as transmission fluid and power steering fluid. Belts plus hoses and air filters are carefully inspected to see if they are cracked, leaking or have accumulated dirt that poses a problem.
Tires, Wheels, and Suspension
Tread depth as well as air pressure and lug nut torque get checked on every axle plus your trailer tires included. The rules of FMCSA require a minimum of 4/32” tread on steer tires and 2/32” on the other tires. Worn springs and shocks as well as air bags are also reviewed, since they tend to tear up tyres pretty quickly.
Lights, Electrical, and Trailer Parts
Other drivers must be able to see you, which means that all headlights, brake lights, turn signals and reflectors must function. Other kingpin, landing gear, door hinges, roof and 5th wheel maintenance solutions are also considered as solid trailer maintenance solutions. Stay on top of grease points as you know Pennsylvania salt and slush can rust them up in one winter.
Why Do Brakes Get the Most Attention?
Brakes are your most important safety system so they get a careful look at every single maintenance visit. A good commercial truck brake service inspects linings plus drums and rotors as well as brake chambers and slack adjusters for all axles. Your tech should check air lines, the compressor and the air dryer, because clean pressure is required for air brakes.
Make sure to not neglect trailer brake maintenance either, as they are very important when it comes to stopping. Professional trucks and trailers brake repair service in Allentown, PA can quickly and easily repair anything that is worn. There are no shortcuts when it comes to any heavy duty brake repair and it needs to be done according to the manufacturer’s specifications and FMCSA brake adjustment limits.
Shop Service vs On-Site Brake Work
If downtime hurts, look for an on site heavy duty brake repair service that comes to your yard. That can save you the towing fees which is a significant advantage for warehouse and delivery vehicles in the Lehigh Valley area.
How Often Should You Schedule a Preventative Maintenance?
There is no one schedule for everyone since your mileage plus load weight and routes all change the timing. Heavy duty truck and trailer maintenance services usually categorize preventive maintenance into different levels, A, B and C. This table details some common tasks, approximate timing and what you may have to pay for if you do not complete them.
| PM Task | Typical Timing | What It Helps You Avoid | Cost If You Skip It |
| Oil and filter change | Per engine maker’s schedule | Engine wear and failure | High |
| Brake inspection and adjustment | Every PM visit | Brake failure, out-of-service orders | High |
| Tire and wheel check | Every PM visit and pre-trip | Blowouts, uneven wear | Medium to High |
| Lights and electrical check | Every PM visit | Tickets, crashes | Low to Medium |
| Trailer coupling and landing gear grease | Every 90 days | Rust, coupling trouble | Medium |
| Annual federal inspection | Every 12 months | Compliance fines | High |
Do not forget 49 CFR 396.17 states that all commercial motor vehicles that you place on the road must have an annual inspection. Most trucks and heavier trailers also must be inspected once a year by a PennDOT-certified station in Pennsylvania.
How Do You Pick a Maintenance Shop Near Allentown?

When signing a contract, request clear pricing, service intervals and a sample inspection report for review.
