ABS AND Traction control lights on

Hello, first - the ABS and traction control warning lights indicate a fault with the same system. They work together. Test this first. You must find out what you know to be bad before guessing at anything else. A chassis module compatible diagnostic tool must be enlisted to check what is going on and what isn't working properly. As far as how the ride is and how it adjusts steering and feeling out of control -- again, test and repair what you can verify to be failed first.. You must realize, besides that, that since the geometry of the vehicle has changed with the lift with unknown components, and likely the tire size is different than "factory" that you will completely change "normal" handling characteristics to some unknown thing. www.repairpal.com/repair-shops It might be advisable, additionally, to find a shop near you that specializes in modified trucks.
