Popping noise at 7mph from stop

[Psycade]

Hey all, I have this subtle pop/knock noise that I hear when I hit 7 mph starting from a stop.
If I accelerate hard from a stop, I don't hear it.
It doesn't matter how slowly I accelerate, it always happens at 7mph.
No popping or clicking when turning (unless hitting 7mph).

I was told it was my ball joint from 2 mechanics and got all new front control arms (all 8) and it's still there.

My other mechanic just told me my front left CV axle had a little play. Could this be the culprit?

Also, I have tire noise and slight vibration above 70mph. Could this be the CV axle?

Thanks!

Now, take this from the guy who’s turned three wrenches in his life and now thinks he’s a mechanic… But my wheel bearings are going bad and at low speeds I hear clicks which is what I’m hoping are the issue

could it be the doors automatically locking?

Sounds like CV axles to me

Get it on a hoist and spin the wheels up. Do you hear a growling or humming noise? if so thats a wheel bearing. I do know of a TSB that states a 'clunk' when braking at lower speeds may pronounce itself. It says to lubricate where the bearing meets the steering knuckle housing.
If you have aftermarket brake pads that can also be the cause of a clunk from a stop. CV axles will have some play in them. Probably not enough to cause a clunk. Unless you are hearing a clicking noise when turning at full lock or on hard acceleration i wouldn't bother with the CV axles. They already got it wrong with the control arms, good chance they are wrong about the CV axle.

As of the 5/6/2024 update stage 1 Jackal tune, the clunk is gone!

99% certain if you're 2016+ (CREC engine) the clunk was your magnetic supercharger clutch engaging/disengaging. The Jackal tune locked it so it's not activating on/off anymore.

I don't have the CREC engine, I have the 2013 - I think it has something to do with the motor mount solenoids.

I had this too. Freaked me out because I thought something was knocking in the suspension or subframe. Went away once I was tuned.
