2004 Silverado ABS Issues

[mnsledboy]

I just replaced the 2 front abs sensors on my Silverado, my abs pulsated once in a while at low speeds and I decided to replace them due to that and age. After new replacements were put in I now get a slight abs pulse every low speed stop I make. And yes I did clean off the hub before installation.

 

What else could it be? There are no codes present. I searched around and haven't heard a similar scenario.

 

Thanks I advance

What sensors did you use? OEM or aftermarket?

[mnsledboy]

OEM sensors, as I can get them at cost.

Are the wheel bearings nice and tight/no play? Clean mounting surfaces on the hub?

Yes my bearings are tight, the mounting surfaces were fairly clean and I cleaned them off more with a screwdriver. There was some but it surely wasn't very much. I'm not sure what is going on

Anyone have anything??

Figured it out, removed senors again and ground down what I already thought was a clean surface, reinstalled and everything worked great.

Yep. Clean mounting surfaces means bright and shiny clean.
