When is the last time you re-torqued all the hub bearings and put them back into spec? .. it is suposed to be done every 250k miles... The most common cause of ABS alarms and/or blown wheel seals are due to neglect of re-torquing all the hub bearings at regular intervals.

Ill check that, truck has about 280k miles. If it is a sensor i would expect it would only illuminate the abs light instead of esp and traction control. This is first time i had an issue with a truck that has a esp/yaw rate sensor...maybe they throw codes differently

Found the problem, one of the modulator wires had rubbed through and was shorting to ground...
