I was just trying to distinguish hub caps as the part that goes on the end of the spindle and covers the axle nut and wheel bearings from wheel covers that cover the wheel and what most people incorrectly call hub caps. Dust covers, aren't they the aftermarket part that keeps brake dust off alloy wheels?
Anyway, the claw hammer might remove the wheel covers but a screw driver works better.
I can't understand why anyone say a wheel bearing job isn't a DIY. That is a job that is about as basic as it gets.
