What could cause a popping noise from the front end when shifting gears or accelerating from 0mph?

Whenever I let the clutch out from 0mph, there are usually 1 or 2 pops just as I get moving. It dosent matter if im going straight or turning, just as my car starts to move there is often a popping / clunking noise. It makes the same noise when shifting into 2nd and sometimes 3nd gear also whenever the momentum of the car shifts forward as I let the clutch out.

It is a front wheel drive 1999 Nissan Maxima

Please throw out any & all suggestions as to what it might be, it will make it easier to inspect components. (No, im not taking it to a shop)

I do a lot of work on my car and have recently replaced a couple things that I thought might be causing the pops, only to have the sound continue after I did the repair. all together in the past 1-2 years I have replaced:

-struts
-rebuilt the brake calipers, new hardware, new rotors
-new polyurethane control arm bushings
-sway bar bushings, end links, & end link bushings
-power steering rack and tie rods
-ball joints
-rear motor mount
-transmission mount
-both CV axles

I have no clue what could be causing the noise. I dont know what to look for because I'm not sure what else could be causing it. I've done what I could to inspect what I could but, surely, i missed something.

Thanks for your help
