ABS, ESP warning lights and stiff steering
I came across this problem after replacing ball joints. You need to remove the speed sensor to get at the bolt. If you don't put it back correctly, you get these warnings and stiff power steering. The metal bolt tab for the sensor has to be installed UNDER the plastic cover, not over....like I did. The STAR service dvd makes a big point of this, so I guess even the pros can miss it. Reinstalled, test drive, lights out, steering normal.
