I have a 2010 ford focus. when driving, the abs light and trax light illuminate, then the engine chugs, and speedo jerks to 0 then lights go off and everything fine. what's up?
Your cv axles may be faulty.The abs sensor is in the hub..What you describe is a cv joint with parts going bad .......sensor, bearing, joint.When they show signs of wear, the abs sensor will not read properly and that will cause the abs light to go on.The cv joint is connected to your tranny, so if it is bad , it will make the engine 'chug' or jerk upon acceleration. I would check both cv joints. Take a look at the joint where it meets the hub/bearing and see if the rubber boot is ripped, if it is , that's a good indication sediment and road debris entered and damged the cv joint. Sometimes, just normal wear and tear ruins a cv joint.It is considered a replacement part.
