How would I find out if its the hub? Or can I test the sensors some how? I have had the codes ran and it says both the front sensors are missing and my brake switch is bad. So I'm at a loss!

I'm going crazy over this same issue and after reading every single comment I can't seem to find a resolution. I have an 01 Silverado 1500 4x4 and about a month ago I changed the fuel pump.(lifted the bed instead of dropping the tank) well after putting it all back together I started getting the ABS activating at low speeds. Thought my rear caliper was seizing up like I've had my others do so I replaced the caliper. Continued to activate the ABS. I had 2 mechanics tell me it was the ABS module so i replaced it along with the ABS pump. Still having issues. Both of my front sensors have been replaced and the system has been flushed and bled. However I have not had it bled through one of the scan tools that does it for you. So my question is could there still be air in the lines causing it, or could it be still a bad sensor or hub/bearing assembling? My ABS and Brake light sporadically come on and have for about 2 years but with no problems to my braking. I just need a solution because its getting costly and time consuming playing trial and error. Also, my DRL and brake lights have starting flashing periodically since i changed my fuel pump to making me believe a ground is loose somewhere but I don't know where.
