Wheel clunk but only when car has been driven 30 minutes plus

[todd]

Hi I have a mystery problem and wondering if anyone else has had it and hopefully diagnosed and repaired it. When the wheel is all the way turned and I am moving at low speed, (like during parallel parking). The car (I think the wheels) make an intense clunking. It only happens after I have been driving for 30 minutes plus and seems to get more intense if I have been driving for longer. Just took a trip and it got really terrible. Arrived at my destination on Sunday night and took it to be looked at first thing Monday morning Of course it had cooled by that point and they couldn't get it to replicate the clunking. They checked all front end parts though and all look good. Any ideas? Is it a computer thing or something with the differential? Obviously the thing to do is to drive it for a while and then bring it to someone but I am not sure what they we physically see and dont want to replace wrong parts in the hunt for finding the problem. It is so specific I thought maybe some other 2019 Crosstrek (Manual transmission) owner might have experienced the same. may thanks
