unknown noise

[dcrusupra]

I wouldn't go directly to rod knock. I was driving my car down the road a couple of days ago and the car just started making a knocking noise out of nowhere. My inner tie rod end is very worn. I already knew what the problem was but if I didn't know, I could see how one would easily make the rod knock assumption. My point is, to make sure not something else.

Try to move the drive shaft up and down and back and forth by hand. Put the car up on jack stands and shake the wheels to see if they are loose, and pull the spark plug wires one by one and if it the noise stops it's rod knock.
