Videos to see and hear what the creak was like.
This is the creak. The car made it when going over speed bumps or on rough roads. I couldn't replicate it for a long time (I always just pushed down on the car) as it only occurred when I grabbed the car at the wheel arch and pulled it upwards first. The creak went away when I turned the shaft just a bit by turning the nut on top of the strut.

This is the same creak while the shaft is turning in the top mount.
