When i turn my wheel left or right......the abs, low trac, service lite all come on.....
You probably have an abs wire problem. GM has problems with the abs wires breaking along the lower control arm. As you turn the wheel the damaged /broken wire looses contact , the computer senses the problem and turns on the abs light. There are repair harnesses available from GM, about $30.00 plus labor for repairing of the damaged harness . Sometimes the abs sensor itself can act up too , especially if corrosion has set into the wiring. In this case you might need to replace the sensor too ( it comes as a hub assembly and is expensive)
most likely the hubs are bad... i had an impala that i couldnt keep front hubs in
