I have a Stratos 200PXL with a dual axle trailer. I don't know how this happened but the chrome looking plastic pieces that surround the oil bearing buddies cracked. I actually heard it happen while I was turning a corner. Any idea of what those are called and where I can get them as well as a ball park price? Any idea of why they would have cracked to begin with? It happened to both round plastic pieces on the drivers side, not the passenger side. It doesn't seem to hamper the performance at all it just doesn't look good with cracked pieces. I know I didn't describe it the best but it looks like some sort of shield (for a lack of better words) that goes between the rim and the hub. Thanks for any info you can give!!!
