Hubs/Wheel Bearings When it comes to hubs, I'm sure we've all read by now that it is important not to "go cheap."
Well out of all of the expensive brands, my advice would be to go with SKF. The reason I say this is because the fronts have an exclusive "X-Tracker" technology which can be read about here: http://www.vehicledynamics-expo.com/...gizshevket.pdf
The vehicle in question from that test was the STS-V. Some more, official, information on X-Tracker can be found here: http://www.skf.com/binary/12-61238/457891.pdf
.
As for the rears, I would say SKF again. One reason would be so as to not mix manufacturers. Another would be because the rear SKF hubs I received were made in the USA (the fronts were made in Korea). And finally, they're on their third design: http://www.skf.com/us/industry-solut...t-3/index.html
Sure Timken is on their third generation hub bearing as well, however, I would tend to stick with a company that went out of their way to come up with something as robust and intuitive as "X-Tracker."
I picked up my fronts (BR930548K) for ~$98 each and the rears (BR930075) for ~$93 each from eBay (free shipping).
EDIT: Those hubs can be had cheaper on the seller's website. $90.92 each and $87.70 each respectively. That's a $22 difference; free shipping too.

A unique double row angular contact ball bearing arrangement (with the outboard row at a higher diameter and containing more ***** than the inner row) increases the bearing’s capacity while improving hub stiffness by 50% over a traditional tapered bearing unit. This results in many benefits:
• Allows the wheel to run truer during cornering and acceleration.
• Reduces deflection of the hub face and wheel, which provides better steering, handling and vehicle dynamic behavior.
• Reduces brake wear due to true running of rotors, which helps reduce brake warranty costs.
• Improves both NVH (noise/vibration/harshness) characteristics and bearing performance.
