Hello all, so I have a bit of an issue I have an 07' trailblazer LS with the abs light on and stabilitrak light on, the previous owner had redid the rear end with a new rear axle. ABS light and Stabilitrak and Service Stabilitrak on. ABS reader said LR and RR sensor malfunction. My Mechanic told me that this rear end does not have ABS. Is there a way I can remedy it so I have ABS again?
