Why Does The Truck Engine Sound Louder Than Usual?

Hi, I'm Mike, a long-haul trucker from Texas. My rig, a Kenworth W900, has been making louder noises than usual when I hit the gas. It's not a grinding or a screeching, just louder. I keep up with maintenance and oil changes, so this sudden change is puzzling. Does anyone have any idea why my truck engine might be sounding louder than usual? Would appreciate any advice.

Hello Mike,

As a professional mechanic with years of experience, I can tell you that there are several reasons why your Kenworth W900’s engine could be sounding louder than usual. It could be due to an exhaust leak, worn-out bearings, or even a failing transmission.

However, it’s hard to say without a proper inspection. I strongly recommend you take your truck to a qualified mechanic for a thorough check-up. A sudden change in engine noise should never be ignored as it could lead to more serious problems down the line.

Stay safe on the road!
