Antilock Activating on dry pavement

I recently had the rear passenger side bearing replaced on my 2004 Tacoma. 4wd. 2.7 4 cyl. The guy I had do it took the axle to the Toyota Dealer to press the bearing and abs ring.

When I got it back from the guy who did it my anti-lock braking begin activating on dry pavement. This only happens as I'm slowing to about four or five miles per hour it comes on then goes off. Any suggestions on what might be causing this? Thanks.

Great. Thank you! I'll try to pull the other abs sensor and clean the mounting surface first. The truck has 340,000 miles on it so my guess is I'll be doing the other sides bearing.

 

my 04 had 240k miles, got your money out of that one for sure

 

I’d be willing to bet the skid rotor is pressed into the wrong position, considering it started after the axle bearing was replaced.
