My Regal (2001 LS 3.8 n/a) sounds like it needs a wheel hub & bearing assembly replaced. I'm looking on Rockauto and find AC Delco 2HF13187 #19235930 on wholesaler closeout for $70 which sounds like a great price for the Delco unit. When I get to the shopping cart, there's a note in red stating "Part is designed for CA Market vehicles". IIRC, the vehicle was originally sold in NM but either way, I don't understand why a wheel hub would be designated for a CA vehicle. Will this hub unit be fine for my application or am I asking for trouble installing it?
