knocking noise

Hi Guys, I have a 2004 Impala SS with 104k miles. Ive been hearing this knocking noise and have no idea where its coming from. Its not my octane because I use Super. This noise occurs when I am breaking, accelerating, turning, basically every which way possible. Could this be my suspension? sway bar? What do you think? Does anyone else have or had the same problem?

If you're sure it's not in the motor, it sounds like a ball joint or shock mount issue. Ball joints will make a knocking sound when they're worn out, and they'll do it every time you turn or when the front end raises and lowers during acceleration/deceleration.

On my 2003 the knocking comes from the intermediate steering shaft that has a long spline and u-joints at both ends. The spline binds up (torque lock) then releases causing a "knock" that can be felt in the steering wheel. Search on this and you will see a "fix" by squirting a lithium aerosol grease down the shaft at the base of the steering column by the floor.
