Worsening front end clunk

Worsening front end clunk
Started out as a metallic clunk during near full lock right hand turns. First noticed during an autox heat. Only noticed occasionally, but sounded almost like a broken spring "tinging" The sound seems to be coming from the drivers side.
After the right turn clunk, if I would stay stationary and turn the wheel almost all the way to the left, it would clunk back over. I cannot get it to clunk stationary unless I "load it up" by making a tight quick right turn. I also can't see any loose parts as it makes the noise.
After inspection of all front end parts, nothing looked worn or loose.
Ordered a drivers lower control arm as it was original and had a torn ball joint Boot.
Replaced control arm with no change.
Replaced upper strut mount bearings with no change. (mounts look perfect)
Replaced both inner and outer tie rods and installed ksport coilovers. With no change.
Removed sway bar end links. Absolutely no change.
Attempted to autox this morning. Seems to be making even more noise around each turn. Every clunk can be heard as well as felt through the steering wheel.
I've read about every front end clunk thread on the forums. It seems to make the same noise cold or warm and consistently bad.
Anyone have any ideas? I ordered a used power steering rack and will attempt to replace mine.
After the tie rod install, I had the rear high pressure power steering line blow. It was leaking through a pin hole in a straight section. Replaced with a used part, doesn't leak Now.

Have you tried with someone else outside the car looking/listening? It seems to me, that it shouldn't be too hard to find from outside, but nearly impossible from inside - there's to much sound transferred to other parts to pinpoint it.

Yes, I have had other people turn the wheel after it is "loaded up." i cant pinpoint the sound through vision or feel. That is why i believe it could be the steering rack. however, it doesn't make the noise otherwise unless it is moving.
I have been fighting this noise for a few months, have inspected everything multiple times and have been replacing parts to no avail.

I have the same noise on full/almost full lock only when im reversing unto my garage. Dealer says it's a normal noise but im not convinced. Have you checked your wheels offset as the tyre might be hitting the spring perch that's where my noise comes from

Ahh right, I have 997 Carrera 3 rims and the offset is slightly wrong so I need some spacers or 996 rims.

Check for movement of the front spring. If there is any play in there, they will snap around under certain conditions yet everything will look fine under inspection. I discovered this issue when I went to Tarret strut mounts. If you have OEM mounts, the little dimple that is supposed to stop the movement may not be doing so.

I will update when I receive my steering rack. Just thought I'd post to see if anyone else had the same issue.
Anyone have any tips for steering rack replacement? Hoping I don't have to drop the aluminum frame under the rack.(and all the associated suspension parts )

Update:
Replaced power steering rack with a used part. Makes exactly the same noise at exactly the same times.
Only thing that hasn't been replaced on drivers side is the forward link. Seems unlikely the issue as it should not move during any steering motion.
Anyone have any other ideas?
