2007 Equinox - Is my differential failing?
Dealership replaced transmission, two new hubs for the front, there is still howling at speeds of 30 and above, feels like something is holding car back and have went from 25mpg to 17.8. Car slows itself without me braking. I also had an alignment. At one point, traction control light, service stabilatrak, AWD off, abs, lights all came on but went off after 7 hours or so. Please help.
