Hello Aidey!
1st of all, sorry for my poor english. I have the same problem with mine... almost ever since. I managed to progress in reducing the rattlle by unscrewing the 3 bults that hold the glass and push it backwards (since I realised that it was missaligned).
So, this helped a lot but not fixed the problem totally.
I have a foto that shows the steps, if you want I can mail you.
Hope it helps.
Afonso
