It is most likely that the Wheel/hub bearing need re-torquing on all the axles. - This should be done every 250k miles, but most truck owners severely neglect doing this. After bearings are re-torqued, the ABS sensor needs to be set to correct distance once bearings are re-torqued.

-- I.E. neglect.

Thanks for the quick answer.
Yes I was referring to the abs sensor but on the dash it says "DA left speed sensor " I don't know why. I would have never taught about retorquing the axles for a solution to that fault.
But I still don't understand why the code is not changing when I unplugged the abs sensors on both sides and when I switched the plugs from left to right it was still the same "DA left speed sensor" message on the dash. I need to understand what is it I'm not getting in this .
