2005 mazda 3 noise on acceleration 63K miles?

I just had the following fixed - Brought my car in for a "womp womp womp" noise that I hear on acceleration and when cars slowing down - Mechanic seemed to feel something in this list was the culprit. After paying over $2k, they say the noise could be caused from transmission issue, and to have second opinioin, which I am doing. Does anyone have any ideas? Wish they had told me this BEFORE doing this work...... :( - Felt like I brought it in for a problem which still exists. (mechanic did mention coudl be possible defective bearing he installed?) WOMP WOMP WOMP :(

replaced:
wheels bearings
front control arms
front struts
front stabilzer links
front brake rotors
front end alignment (which PULLS TO THE RIGHT NOW)
Front CV axle
Front Inner CV Shaft
