Did you do all that maintenance yourself? Or did you pay a guy? I'm going to assume that in the process of ripping all the front-end stuff apart he snapped one of the ABS sensors off or broke it or didn't plug it back in or something but I'm willing to bet that there's a sensor somewhere thats whacked out should try and get it up in the air and take a good look at everything under there make sure everything is plugged in and nothing is snapped or broken.

not exactly related in my third gen my four-wheel drive stopped working I even posted a forum of here A bunch of years ago about it it ended up being unplugged from something I was doing and forgot to plug it back in.

It's a little different but I just did all of that same maintenance on my car Lexus ES granted that's a car the chances of breaking one of those sensors during that maintenance was very high considering their location.
