I have an 05, 5.9, 3500,dodge ram with a very bad knocking noise is hard to tell where it's coming from. I could surely use some advice as what it is. Please let me know what to do. Thanks Fred
Hi Fred, welcome.
Do you have any codes, and if so what?
Start with killing the cylinders one at a time to see if you can eliminate it in one cylinder identifying which one.
Can you do a video of it so we can hear?
