Sounds like my right front hub bearing is going out. I hear this light whirling noise around 40-60 mph coming from the front. It is speed sensitive. I can even slightly feel it. Mostly on a left curve turn. When you shift the weight (to the left) off the right side, the sound goes away.

To me, this seems like an indicator of a bad hub bearing. I will be replacing them in pairs of course.

My question is, which brand replacement has shown to have been of the better quality replacement for the OEM hub bearings? Or is the OEM's the best quality known?

I put Precision from O'Reilly on mine this afternoon, $160.00, they have a cheaper brand at $ 105.00. Rock auto has some for less but I wanted instant gratification.

I have had my Timekins, or whatever they are for four years. They have lasted longer than GM ones.

I was leaning towards Timkens as well, but I had thought someone had mentioned that there was a better American made brand. I knew Timkens used to be made here, but someone mentioned in the past they were now made overseas....idk. Maybe it doesn't matter anymore.

Moog - here is why: the cheaper ones ride the bearing on a flat spot instead of a u shape. All the load is on one tiny portion of the bearing. Go Moog or a similar style bearing (Verify it!) or you will be doing it again in 1-3years.

Check your AWD carrier and at least grease it while you have that axle out

Moog and Timken both made in Korea. Probably in the same factory with the same components.

I was actually thinking about purchasing a new AAM carrier unit and just replace it. I know....with my luck, that will be the next part to take a shit.
