I have replaced the two front tires, finished all three motor mounts today and the driver side CV axle and wheel bearing.

I notice it's when I'm really stepping on the pedal but mainly when I'm driving, and the road goes up and down. It was harsh but I did the lower torque mount today so it's very slight. I've had it a year and it had issues from the parts I replaced but it's almost done lol. Any ideas?

It sounds like one of the engine mounts might be defective or an inferior part. Can you please shoot a quick video with your phone so I can hear the noise? That way I can tell for sure what's going on. You can upload it here with your response. Also does the noise/feeling change when you are accelerating?

The noise only happens when I accelerate hard, accelerating over a mini hill. When you go over it, when you feel the car go down you can feel it. I'll upload a video later my wife has the car lol. I replaced the first engine mount last year then the next 2 yesterday and a couple weeks ago so maybe the first one I did went bad, i guess.

Yes, that could be especially the torque mount which can cause the problem you are describing. Please upload the video when you can.
