My 98 2.3CL automatic has been making some very loud groaning/knocking noises under a very specific set of conditions:

• Decelerating from ~60 to 50 mph (foot is off of the gas and brake), but only if the steering wheel is straight or to the right
• Making a hard right turn with foot off the gas (like a horseshoe exit from the expressway
• Giving a good amount of gas in Reverse (both when the car is moving in Reverse, or when I rev the engine in Reverse with the brakes applied and the car is not moving)

It's an awful sounding noise, like metal is groaning and ripping apart or grinding against something moving. I'm wondering if it's a bad engine mount? Any thoughts?

 

Doesn't sound like a motor mount, sounds like a bushing or ball joint, or it could be your cv joint going bad

 

Could it be a ball joint or CV joint if it makes the sound even when the car isn't moving? It will make the noise in reverse if I rev the engine with the brakes applied.
