I just had a shop change a left front wheel bearing on my 03 4runner V8 and the ABS light came on after picking it up? the shop told me that it was the bearing itself and to take it back monday to replace it. They said it was not reading the the part signal??!! I changed out a wheel bearing before on a pontiac and never encountered this problem how does a bearing produce a signal and the senosr not read it? Am I getting you know what? The good thing is they will replace at no cost to me but I wanted to know anyone else had this problem?
