The ABS light came on and the reader indicated the right front bearing I replaced was the culprit. It indicated a problem with the ABS signal circuit. I disconnected the battery, inspected the harness and didn't find any issues. I reconnected the harness, the battery and started the vehicle. The ABS light was off and I cleared the code from the pcm history. I did however find grease seeping from the inner seal, I called Moog and was told to send it back for replace. Any ideas as to why this happened or is it that I just happened to get a defective bearing.
