Front ABS sensors not reading.

Recently, I swapped out my front abs sensors on to my new pro comp spindles. I took both out and put them in the new ones. Now both sensors are not reading. All I did was remove them and install them in the new ones. What could cause both to have a error. I could see one but both seems strange. They worked fine before I moved them over. Now I'm getting all the dash lights lighting up and the limp mode kicks in. I did scan it and just got both sensor not reading. I did also replace the front wheel bearings too.

 

They may need to be shimmed to the new set up. You may have to measure to correct the problem. Or maybe you need to buy sensors made for the new setup.

 

I had old pro com spindles on before and got new spindles. I had the old designed ones on the truck. So everything is the same just new hubs, so i don't know why both are having problems. I'll pull them off and test them this weekend. I know the fit was tight on these spindles and the kind of have to twist a bit. I may have to remove some metal so the fit right. I had to use a screw driver, to pry on them to get the bolt in. I think that might be a problem for them since I had to do it to both sides.

 

Update. Pulled hub off and cleaned, both sensors had grease on them. Replaced sensors with new ones, and reset computer. Everything works now. I broke one sensor getting it out so I just replaced both since I had to replace one.
