I've got a Hoyt RX1 and its got a bearing going bad in the top cam. I understand Hoyt will replace these under warranty but I am not the original owner of the bow. Does anyone know where I can buy one? Are the bearings standard or different depending on the cam? I have Hyper ZT cams. I talked to my local bow tech and he has never changed one. Are they easy to change? Thanks for any info.
