20 Things To Check Before Buying Used Semi Truck

If we test drive a new car then we should triple test drive a used semi truck. Feeling the vehicle how realistically performs will give you a wider picture of the truck performance.

Drive it for a while to feel the power of the machine and in that way, you will see how that used semi truck is performing on different terrain incline. You are buying used semi truck that needs to safely transport goods across the state no matter if the truck is driving trough the most dangerous highway running true a straight highway.

12. Check the Oil

First I want to point the importance of the oil and remind you how important is to check the oil before you buy used semi truck.

• The oil makes the parts of the engine move without interruption and in that way it allows full power of the engine

• It has cleaning qualities and protects the engine
• It improves the fuel economy

So why is so important to buy a used semi truck that had an oil change on a regular basis?

• The engine oil has a limited life and in a case when the oil is overused it becomes contaminated with metal traces and dirt.
• The density is higher and has opposite effect from lubricating the parts
• The truck is becoming less powerful

13. Check the Brakes

What is a truck without brakes? I would say a beast out of a cage in the middle of a crowd. 80% of the trucks have drum brakes and the problem with these truck brakes can be corrosion which can increase the risk of a crash.

Because we are talking about a used semi truck which means that the truck was few years in service I have to mention that NHTSA’s require from the owners that have trucks older than 7 years to:

• Keep close look on the brake system for any signs of corrosion
• Perform regular professional inspections for loss of brake fluid

That is why you need to check the brakes visually by yourself for noticeable problems and before you pull the wallet from your pocket take that used semi truck to a professional service center to remove the wheels and check the entire brake system for defects.

14. Check the Lights

Truck lights also need to be checked because you know that the standard lights need to be in function when you turn the key on. Start the used semi truck and step out of the truck. Walk around the truck checking every single truck light that is required by Federal Safety Regulations.
