Mr. Veerawat Manatsapakorn, or "Hia Vee," CEO of Hor Yai Auto Parts Co., Ltd., a distributor of V Force brand suspension parts for pickup trucks, revealed, "The unfortunate thing is that many vehicle owners don't lose money because of expensive parts, but because they let their vehicles break down until the problems spread." He explained that from his experience working with transport operators and repair shops nationwide, he found that most damage could have been prevented if vehicle owners understood the causes of wear and tear and planned for proper maintenance.

5 Risky Points That Pickup Truck Owners Should Check Before Their "Money-Making Vehicle" Becomes a "Money-Eating Vehicle": Based on extensive business experience, five risky points that commercial vehicle owners should monitor before repair costs escalate to hundreds of thousands of baht are identified.

1. Suspension System: Overloading = Premature Failure. The suspension system remains the most frequently damaged part of commercial pickup trucks, including the steering rack, control arms, drive shafts, leaf springs, and rear axle. The main cause isn't just the quality of the parts, but also exceeding the vehicle's limits. The suspension doesn't fail from excessive driving, but from carrying weights beyond its designed capacity. Although most pickup trucks are designed to handle loads of around 1-1.5 tons, in reality, many transport vehicles carry 3-5 tons, and in some cases, up to 7 tons. Combined with potholes and rough road surfaces, this puts more stress on the suspension system than normal, resulting in shorter lifespan and premature damage.

2. Heavy-duty leaf springs: The heavier the load, the more you need to invest in the suspension system. Heavy-duty leaf springs are popular parts for heavy-duty vehicles because many owners like to reinforce them to increase load capacity, especially 20 mm thick leaf springs designed for heavy-duty work. However, even with reinforcement, leaf springs still have a limited lifespan. Continuous use under heavy loads for extended periods will cause fatigue and deterioration. Neglecting inspection can affect the entire suspension system. While reinforced leaf springs increase load capacity, it doesn't mean unlimited load capacity.

3. Clutch and transmission system: It's not mileage, but "driving habits." Transport vehicles that travel hundreds of kilometers daily often experience faster clutch and transmission wear than regular vehicles. However, the key factor isn't just mileage; it's driving habits, including aggressive acceleration, abrupt gear changes, and continuously carrying heavy loads. This puts excessive stress on the clutch, flywheel, and gearbox, resulting in repairs or replacements sooner than expected.

4. Electrical System: Damage often starts with minor issues. The starter motor, alternator, and air conditioner compressor are another group of parts frequently affected in commercial pickup trucks, especially those with continuous air conditioning use or idling for extended periods while waiting to load or unload goods. While many consider this normal, this type of usage unnecessarily forces the electrical system to work continuously, reducing its lifespan.

5. Engine: The most expensive damage often stems from neglecting warning signs. The engine remains the most expensive system to repair, including the cylinder head, crankshaft, and cooling system. However, most problems don't occur immediately but gradually accumulate from minor malfunctions that owners overlook. Changes in engine noise, abnormally high temperatures, or low coolant levels are all warning signs that shouldn't be ignored. Continuing to use the faulty engine can lead to extensive damage requiring a complete engine overhaul, which is many times more expensive than preventative maintenance. Most engine failures don't happen suddenly; they occur because owners choose not to regularly inspect the vehicle.

Revealing 4 Misunderstandings That Lead to Higher Repair Costs for Vehicle Owners. While many vehicle owners intend to reduce maintenance costs, the reality is... Common Misconceptions That Lead to More Expensive Repairs: 1. Choosing the "Cheapest" Parts: Cheap parts may save you money today, but if they're not up to standard or unsuitable for your vehicle, they can damage other parts and lead to much higher repair costs. 2. Waiting for the Car to Break Down Before Repairing: Most car damage starts with minor issues. Ignoring them until the car is unusable often results in large repair costs and lost income due to the car being out of service. 3. Replacing Only Defective Parts: Many car systems are interconnected. Replacing only faulty parts without checking related components can cause the same problem to recur soon after. 4. Overloading is More Cost-Effective: Overloading may increase short-term revenue, but it's a major cause of premature wear and tear on the suspension, driveshaft, and transmission, ultimately resulting in costs exceeding the increased revenue.

"The most expensive repair cost is the cost of prevention." "Heawee" believes many car owners don't lose money because of expensive parts, but because they let small problems escalate. "Many people try to save money by choosing cheap parts or waiting for the car to break down before repairing it, but ultimately end up paying more because the damage spreads to other parts. The best way to reduce costs isn't by buying the cheapest parts." "But it's about taking care of your car before it breaks down."
