Thanks everyone, I will make sure to use PB Blaster next time.
The wheel hub got here today, so I installed it.
Wheel bearings are always interesting. What vehicle, what mileage, and how much did it cost if you don't mind sharing?
It's for my own RX-8 w/96k km on the clock.
Dealer charged me CAN$300 for the part. If you go to US sources, prices vary from US$50 to $150. Probably won't trust the cheaper ones, and by the times the trusted ones get into Canada, it won't be much cheaper than the dealer. The thing is kinda heavy and probably costs to ship.
I have no idea why it's worn out this early, by the way. The only guess I have that kinda makes sense is that it received a shock from that raccoon I ran over at 65 km/h a while ago. Otherwise, I have no idea.
