I replaced my CSB and now from time to time it squeals/squeaks. I took a look and it seems that the dust cap towards the front of the car is spinning with the drive shaft and rubbing against the rubber of the CSB causing squeak/squeal. My question is can I leave these caps off? Both of them probably take up 1/32" of space. It's a sealed bearing I'm not really worried about it getting dirty. If anyone has run into this and has any tips let me know. Thanks
