Hyundai: 200Accent Rear Bearing

Hi All..

I've noticed the rear hub bearing assembly on my wife's 2000 Accent is
getting quite rumbly and I inquired as to the price of a replacement. WOW!
$165CAD +tax.
Does anyone know if there's a way to replace the bearing inside or am I
stuck buying the whole hub assembly? I'm not trying to be cheap, just
wondering if it's the only solution or can the bearing itself be replaced as
I have pullers and presses.

Thanks for your time.. Steve
