Oh god help

I have been having this problem for awhile now, the ABS light SVS light and trac off light have been periodically coming on. I had both hubs changed, got one bad hub replaced that hub lights still coming on and still having some wheel noise and vibration. A mechanic friend took it for a ride and concluded that it isnt an axel and that if we changed both bearings it shouldnt be that. What the hell else could it be I am so frustrated coming to wits end soon. As previous posters have stated already took it to the auto parts store and got a no code reading. My mechanic friend is taking it to his garage today to throw it on the computer without his boss knowing lol. If anyone has an idea what to check next I would greatly appreciate it

You *might* have a bad wheel speed sensor jumper harness instead of a bad hub/sensor. GM has a bulletin on replacing the jumper harnesses, with part numbers for specific vehicles. Apparently, the harnesses test good on the bench, but fail when driving due to suspension flex and vibration.
