Terrible/odd noises in front end. New to this.

[StackedTDI]

Recently got myself into my first project. Got a fairly decent deal on a 06 jetta tdi. Already hoodstacked and deleted. Had 380k. Needed some work. Put a 130k mile motor in, runs just fine, same trans. Possibly 380k. Did hubs and cvs, rotors, skipped pads in the front(looked fine). Have went through atleast 4 autozone cvs, continue to have an odd grind/clunk near the driver side cv that I can oddly work around when operating. Between gears, no load, moving it sounds horrible. But quick shifting and getting into gear it doesn't sound horrible. When slowing down hitting the breaks and coming to a stop fast seems to make the noise even out... any ideas. Have people saying trans bearings but would take any recommendations. Anyone else had a load of bad cvs from autozone? Or any parts store inspecifically?

Cv's don't grind. They only make a clunk/clicking sound. Or feel out of balance when driving. kind of feels like a out of balance tire but is accentuated when accelerating hard.
Is there any slop in your cv flanges on the trans? With the car off and wheels in the air is there any noise when turned by hand?

Sounds like the noise is made worse by the wheels turning the trans being pushed by the inertia/weight of the car? Which is why when you brake it gets better and the noise is lessened.

When everything is tightened down trans side of cv there is not major but slight in and play when pushing toward and away from trans. Is that abnormal?

 

[GlowBugTDI]

Possibly, I am not 100% sure honestly. I don't think that would be much of an issue. I would be concerned about side to side play, but minimal in and out should be ok. I don't think mine has any, but I haven't really checked for that.

There's not any side to side play. But if their was, what would that indicated? Or does the consistent cv issue tell me there is something wrong in the transmission such as bearings?
