Remember that is only bearings!!! That is why it is so cheap. If you want to go that way then it is all yours. I bought the NAPA because everything is brand new, and a full unit.
The green store and Vatozone cut corners like that, but it saves people money. I wouldn't call it a bad part, I don't like being cheap on my truck when I can get a brand new unit.
Also before you do that, there was a service announcment on the stock Dodge hubs saying they CAN fail under extreme heat. Even though I have not heard of that happening, NAPA claimed to fix the problem with their updated hub.
