It was on a four post lift and also two post lift to check the things. Luckily, I have a very good garage, which was the first "British Leyland" Garage in Austria and still a sanctuary for british car lovers, but because the garage is totally overbooked I try to find and repair things instead of waiting.
I see, there are a lot of additional possibilities for the rattle, maybe it will be a lifetime destiny. On my old Jaguar XJ40, I searched 2 years to find out that the rattle was from a small washer on the shock absorber and was amplified through the body.
On think which makes me wonder, the rattle is always there regardless of the road surface. I couldn't say it gets worse on uneven roads.
So next steps:
- I will change the anti roll bar bush, I already bought it, but I did not changed it because it looked like lot more smaller then the one, which is mounted.
- Check the "interiors" of the door
- Search for additional lose bolts (that is something I used to it, have to do it every 500 km on my Royal Enfield)
I will keep this thread updated.
