Abs Light On Gmt-800 4wd

[tobinstetson]

I had my summer tires put on by my mechanic a couple weeks ago and now everytime I hit a large bump on the road my ABS chimes and the light will come on. When I first start the truck everything is fine but once I drive and Hit a bump it does it everytime.

 

My ABS is not acting up and my brakes work perfect. I have replaced both front wheel bearings (ABS activating on dry pavement was one reason) in the past year.

 

Could this be a loose wire to the sensor that moves with a lot of suspension travel? Maybe my mechanic hit it while changing the tires or greasing the front end? maybe a fuse loose?

 

Any ideas would be appreciated
