2004 Cadillac Concours • 6 cylinder 2WD Automatic • 80,000 miles

2004 Cadillac CTS 3.6l: I replaced the passenger side rear wheel hub assembly today with a cheaper alternative to the high priced wheel hub assembly at he dealer. After I replaced it, the noise is still there (low groaning noise from the rear of the vehicle) and now the ABS and TC light are on. I am assuming that instead of the rear passenger side that was bad it is instead the rear driver's side that is bad. What do I need to repair/do to get the ABS and TC lights to go off and are cheaper alternative parts OK to use instead of the high delaer priced items?

It looks like you may have not only changed the wrong part but created a new problem in the process. I realize the parts are cheaper but there are problems that can come along with that Chinese made junk too.
