I've experienced the same issue within the last week. Initially got the creaking sound that many have pointed to being an issue with re-greasing the upper control arm, however the clunking/shaking got bad and I discovered the loose bolts on the lower control arm.
I was not at all comfortable driving the car, had it towed to the SC and tried to surface some of the conversations found here and even the recall.
The SC guy told me that, I stated there was an issue with the "lower control arm" however the recall is specifies "lateral link" and that it would not apply. I'm not technician, and so I made the assumption it was lower control arm, but it seems to be the exact issue reported in the recall as well as threads posted here and I feel as if they are just dismissing me in order to hit me with the bill.
I'm out of warranty currently, as this is 2018 model, but under 50k, they gave me an estimate that was 240 for the upper control arm creaking + ANOTHER $240 to inspect the bolts and rattling I experiences. They said these charges would be incurred on top of any service that needs to be carried out which sounds absolutely ridiculous. I feel most times diagnostic charges are then credited to the repair itself, but at any rate I expect them to cover the labor on good faith.
Really curious if anyone's experienced this and has been able to pull a favorable outcome. Is it worth my time to call tesla corporate?
