Thanks SHOdded and ZSHO,
Rock auto is where I was looking, but from what I can see most of them either specifically say not for the PP or they don't say anything one way or the other. There are a few that say front for the PP.
Any idea on what would be different about a wheel hub on the PP? It just doesn't seem like a componet that would be upgraded from the non-PP SHO. Also, I've seen several sites mention on the regular Taurus that the front and back wheel hubs are the same, I was wondering if that would be true for the SHO as well. If I can't find a reliable answer I guess I will just go with OEM to be safe.
Also, why both? I don't mind doing it but I have changed many hubs in my life and only ever one at a time as it they wear out. Will having a new one on one side affect Performance in some way or are you just thinking if one is bad the other is following closely? I have 80,000ish miles. I've never had a hub wear out this fast, nor have I ever had a rear one go. (I've been told it was due to cornering too aggressively as to why I wear front hubs out quicker. No idea if that's accurate.) I've driven several vehicles into the 200k range.
