I replaced both of my fronts last fall at roughly 85,000 miles due to noise on turns that I couldn't hear, but others could.
I replaced one with a NAPA hub, and the other from Advance. They were roughly around $100 a piece and I've used these hubs previously without problems. Within 2 months, I was getting the ABS/Traction control off along with the service stability system. A scan showed RF WSS intermittent. The local NAPA warrantied it, and gave me an upgrade to their higher lever hub ($234!)
Recently, the warnings were back. Now, the same thing with the LF hub from Advance. This one I'm replacing with one from Intense
that I bought during their weekend sale.
The bearings seem fine on both, and after talking with my usual parts supplier, he said that more of the "cheaper" ones are having problems with the WSS. So, if you want to save some time, get a good quality hub. Unfortunately, those seem to be becoming harder to define.
