The groan can be a bad wheel brearing. The abs light flickering is a dirty or faulty ABS wheel sensor. Take it to another mechanic.

I had the same problem with mine.I changed three wheel bearings and no results.Finally I asked a friend of mine who used to work as a technician at a GM Dealership,and he told me it was the harness that goes to the wheel bearing.You will have to get it scanned to determine which one is faulty and go from there.The part costs about $120.00 CND.It is a dealer item only.
