My PWT is less then 3 weeks old and I have just noticed the tray has significant movement on one side, I do not recall it being this way when I first took delivery.
That actually looks normal - or certainly like mine. The drawers we use are DVD computer drives and don’t have a great feel to them, but they work well and sound great. If it ever becomes a concern, we’re happy to replace it for you.
My drawer acts the same way, no worries. The drive is the weakest link in the mighty PWT, but also the cheapest to replace. I don’t think your’s needs replacing though.
