Rear Wheel Bearing Failure - Not even 300 miles covered!
Hi,
I just replaced one of my rear wheel hub and bearing assemblies.
Ive done less than 300 miles with it, and it has gone bad already.
Its NOS delco item. What on earth would cause it to fail already?
I fitted it with extreme care, and tightenned the axle nut to 164lbs according to the service manual with a brand new torque wrench.

I have just taken out the hub and bearing assembly out of the vehicle.
Bearing grease has been thrown out of the front lip seal of the hub assembly onto the emergency brake shoes. Why the hub assembly has spat grease out is beyond me. But i'd imagine that if grease has been spat out, then there's less grease for the bearing assembly where its needed for lubrication. Then bearing failure would occur. Thats great isn't it, after less than 300 miles. &^% GM and their designs, pack of useless u know whats. Or, ive struck it unlucky and copped a fault assembly

I'm inclined to turn a skeptical eye toward these claims of NOS OEM stuff, especially considering that there seems to be an endless supply. And if it is really NOS, how old is it and do you really want an old bearing? Grease has a shelf life and the oil eventually separates from the solids. Since the Corvette wheel bearing is a truly sealed unit, there's nothing that can be done about that. IMO it ain't worth it, I'll spend the money for new SKF.

I was told that when ordering OEM parts, not to ask for white box parts since those are made in China. I did this when ordering break pads that were made in Canada.
