Hear the knocking when starting, in reverse, forward movement, turning--just all the time. I do know the rotor on the brakes are warped. Could that be causing the knocking?
What is knocking sound? Struts & bearings replaced on both sides 5 mths ago. on 2004 Honda Element
when does it knock? when going over bumps? I read to fast or miss read. Sounds like a motor mount. Have someone shift through the gears while watching the engine bay. If you see the engine move, look for where the movement is being allowed. Front, sides, back, or under it. Maybe you can follow the noise.
