    ABS activation issues

    I have a 2007 GMC Sierra with a Rancho 6” suspension lift and 35-12.5-20 tires. I have been having issues with the ABS activating at low speeds when turning. I have replaced the hub assembly’s and speed sensors, but to me it seems that the outside front wheel on slow speed turns is activating the abs. I don’t even have to be on the brake and it triggers the ABS light and pump, but it’s wheel specific. If I turn right it’s the front left, if I turn left it’s the front right. I have hooked a Tech2 up to it and can’t find any codes. I know on the classic body up to 2006 you could change the tire size in the system, not seeing it on this truck. I do have the JL4 system on the truck which I think is stabilatrack. I am at a total loss on how to correct this issue. I know the computer hasn’t been changed to match the tires as it’s 5mph off. I can’t have the only truck that’s had this issue...help!
