    Thank you Jeff Armer.. You know I tried pinning the knocking sound using a stethescope and its not coming from top or bottom of engine itself. Its louder by the power steering pump. And even so as car runs at idle, it suddenly wants to force turn off and it actually does if it ain't given a little accelerating. Still think it's what you mentioned or is there any hope of it being something else?

    With knocking noises it's hard to say without hearing it myself ! I would suggest if the vehicle were driveable run it by a repair shop an let another Tech have a listen . The best i can tell you .

SOURCE: 2004 chevy cavalier makes a ''knocking'' sound

This could be any number of things. It could be your CV axle going bad, your tie rod joint has gone bad, your lower ball joint has gone bad. More than likely it will be your CV axle. What you need to look for is rips on any of the boots for these parts. The one that has the rip will more than likely be your problem. Just check for grease coming out of any of these parts and you will find your culprit because it has dried up and is causing the knocking sound. Let me know if you have any further questions. Thanks for using FixYa!

I have a 2003 chevy cavalier and is making a constant loud knocking noise on the inside passanger side. What could it be? Please help!


My 03 had a recall on the HVAC controls, it was getting stuck inside the HVAC box and making a clicking or knocking sound from the same area

It ended up being something like a door that moves when you switch the air from moving from the defrost to the feet position getting stuck

Hope this helps

If you are hearing a loud "knock" and it is coming from the bottom of the engine you probably have a bad crankshaft bearing(s) which means engine rebuild or replacement.

My 01 has a bad knocking noise what does this mean?


it means that you need to research either a different car, or a different engine for this car. A loud knocking noise indicates a connecting rod is loose, and your engine has little to no time left before the rod or endcap breaks, completely messing up your engine, and making it very difficult to change. If you must drive it, drive it slow, and be super gentle with the gas...like you're driving on ice. If it's more of a ticking noise, that could be a lifter, but a loud hollow sounding knock is a rod. You may also have a check engine light showing up on the dash from the knock sensor.

Knocking


Most likely it could be a vavle or it could be something with the exhast. Hope for the exhast. Replacing vavles are costly.
