WHOO HOO! Wait til you hear this!
I checked out the so-called one piece hub-rotor. It is the same as the two piece setup, except it is already assembled with the lug studs and even has the bearing races installed in the hub. It WILL come apart and I found out that rotors are available separately. In other words, if you need a rotor, you don't have to buy the whole hub-rotor assembly again. You can't buy just the hubs though, to get hubs, you have to buy the hub-rotor assembly.
So, I asked the price again. The parts guy said just rotors were $146.06. Now, I'm not sure if that was each, or a pair. Next he said the hub-rotor assemblies were $229 each. That would be $458 for a pair. Still not too bad for hubs, bearing races, lug studs, and rotors, and already assembled even.
Now for the REAL good news! I said to the guy, "I was told when I ordered it that it was $165." Without batting an eye he replied "Well if that's what you were quoted, we'll stick by it." I said, "OK, I'll take this one, and order me another one like it." I figured I'd end up paying the $229 for the second one, and really didn't have a big problem with that, but when I got home, I looked at my order receipt, and he charged me the same $160.65 for the second one!!!
So, I got two brand spanking new OEM hubs with bearing races, rotors, and 16 new lug studs for a grand total of $321.30!!! I am one happy camper this evening needless to say. (The hubs are apparently made by BUDD as it is cast into them.)
