Whats crazy is the original wheel hub is still on the passenger side with no problems what so ever. I'm guessing they are AC Delco wheel hubs? If they weren't so darn expensive, I'd replace them with the Delcos but for 100 bucks and a 3 year warranty, I'll give the Moog's a shot. Its really not that hard to replace even If I have to replace them in 2.5 years.
