right front hub assembly

Hi,will a worn front hub assembly make a pronounced "growling,grinding" sound while the truck is in motion? This is on a '99 Silverado 4x4.Thanks for any input

70 Caprice...if you find you need a new hub I have one with the ABS sensor that I bought for my 2000 K1500 and never used. It is GM part number 15740291 which has been superceded by part number 15233113. I know they list for 230+ dollars but I bought it awhile ago for 140$. I'd sell it for $75 plus $20 for UPS ground shipping...it's heavy. It's never been installed.

To answer your question, yes, it will growl rumble. Does sound like wheel bearings to me. Just had my driver side replaced.
