I got a Replay Pro recently… One of it’s caps is kinda loose and makes rattling noises mid spin… How can i rectify this? The cap isnt really moving in the vertical direction much but it rotates in place … It is the non-bolt side cap Any help would be greatly appreciated Also…i can spot large air bubbles in the 2 sides…is this normal? ---

Rattling caps can easily be fixed by crimping the edges of the caps just a tiny bit. I use pliers to just pinch the very edge of the cap which usually fixes the issue. Don’t go all around the cap, crimp one or two small spots at a time, if the cap still rattles then do one more and try again. The caps are pretty easy to remove and work on - There are holes in the plastic under the response pads that you can stick a toothpick or allen wrench in to pop the caps out. Not sure about the air bubbles you mentioned, a picture might help. ---

So i remove the cap, crimp the edge and then stick it back in? ---

That’s correct.
