I had the problem before i changed my wheel bearings, my ABS will work a few times, then the light comes on and it stays on until i turn the truck off and restart it. I heard things about the sensors in the wheel bearing itself, but why would mine keep tripping if i have BRAND NEW bearings???? PLEASE HELP

 

There is an issue with the ABS sensors and wheel speed sensors in the trucks which causes the problem. I have the same one in my truck. Let me guess, it's a 01? lol.
Did your hub assemby come all together with the new sensors? I think you can get them without them so are they actually new sensors?
You might want to investigate the ABS control module too. They have a habit of going. Also, just a tip, post your vehicle information either in your sig or your post when you post. It makes it hard for peopel to troubleshoot when they don't know what they're dealing with. I just assume you have an 01 because of your user name.

 

yeah the new bearings came with new sensors, how should i investigate the module?is there a way to like test it?

New bearings doesn't automatically mean that the airgap is proper. It should be, but it all depends on the quality.. Check the mV-AC output according to the thread below and let us know the results:
