I understand your concern about the ticking noise from your Freightliner’s engine. As an auto mechanic with over 20 years of experience, I can tell you that such noises can be caused by a variety of factors. It could be due to a lack of lubrication in the valve train, a worn-out serpentine belt, or even fuel injector noise. It’s hard to say without inspecting the truck. I advise you to take your truck to a professional mechanic for a thorough diagnosis to prevent any potential damage.
Remember, regular maintenance is key to keeping your truck running smoothly.
