Has anyone had their dust covers pop out? I had three pop out and roll around the chrome hub the covers the end of the axle. We went thru rain and the left front axle bearing went out. and the rear need to have the outer bearing to be replaced also. both axles bearings were on the left side. I only drive 55 and everyone was passing us and sprayed the wheels on the left side. I've asked several people here in Elkhart In. about what might cause this to happen. All bearings had were well grease, so the bearing didn't go bad because it didn't have enough grease.
