HELP: steering rack

[A8 Doc]

Sure it's not one of the many suspension arms?

Cheers guys
I've had upper suspension arms changed just over a year ago.
My guys checked all upper arms and there was no visible damage at all.
It gets noisy ONLY when its hot/warmed up by the engine's hot air which fills in wheel arches if you know what I mean.
I will get some pictures in next hour.

When it gets up to temp its really loud, very loud, inside and outside.
I will go to Morrisons now and try to warm up the car and record the sound as well

I'll be back soon

So....got all the possible info for you guys.
'My guys' are either blind or...whatever, but as my Audi garage is over 30miles across London (approx 2h drive one way) its quiet difficult and time consuming to go there each time I have a question, any way...

Lets start from the noise
After around half an hour of running the engine in standstill this is what's happening
Please turn the volume up to max

INSIDE, phone placed by the tax disc just in the bottom left corner of the windscreen

OUTSIDE, phone placed on top of the tyre (left)

Now, I'M SORRY IF THAT'S WAY TO MANY PICTURES, most of them might not be relevant as the damage is clear on the upper suspension arms, but I am not a mechanic so just want you to have a look at other joint, which to me look fine.

The one with smaller cracks is much quieter AND it needs another 15-20min to start making this horrible noise.

BUT the real question is: Are this cracks the possible source of that horrible noise, it just sounds unreal for something so minor to cause such a LOUD noise????
And why it's completely silent when cold??

I had the same problem around december and changed all 4 upper arms with OE TRW arms from http://www.mister-auto.co.uk/en/ as they had TRW and were a great price. I still had a bit of a creak and a rattle that got worse, so did the lower arms, which felt great but noise still there, so took to Audi who diagnosed antirollbar and changed that, car drive like like new, beautiful.

If you do the arms yourself, get the proper instructions from ELSAWIN software and check the heights of the arms when you tighten the bolts, they should be way up in the wheel arch and then you have to wrestle to insert them into the hub carrier. Many garages just tighten the nuts with the suspension on full droop, so the bushes are all twisted up when at normal driving height.

Hmmmm...OK, so more likely not a steering rack?

How does the TRW compares to Audi part?? I know that some aftermarket one can last not even a year, TRW rings the bell as a high quality replacement??

To repeat my question, would this cracked rubber cause sooooomuch noise when it's warm/hot???

Am I write that two upper arms needs changing (one on each side)
them two
right one
Thats the one??

Sounds a bit out of the norm but if your looking to replace ball joints anyway, how about a syringe full of gear oil and inject it through the boot into ball joint to see if the squeaking goes away and if it does you know what needs changing.

UPDATE

4x upper arms to start with.

I think I asked it before.
TRW or Meyle HD guys?? or any other.

Got upper arms 18months ago from GSF stupidly and there you go, year and a half and they need changing again

I think Psyche mentioned that TRW do upper arms for Audi!?
