Q: Knocking sound

asked by on February 17, 2016

I hear a knocking sound at the front of the truck.

The noise may be the serpentine belt tensioner vibrating, or the front engine damper is broken and causing a noise. If the noise is neither of these components, then an inspection would be needed to see what the possible cause is; a low thump or knock could be a major internal engine problem. I recommend have a mechanic, such as one from YourMechanic, inspect and isolate the noise, and provide you with a diagnosis.
