I've only ever hit the brakes really hard once.It was at night and I was driving into a town i'm not familiar with and didn't know about a sharp turn ahead and had to hit the brakes from a speed of about 65 down to 30 in about 2 seconds...lol.
I don't recall hearing any "ABS Sound" when I did that.889598.I know the box your referring to.It's mounted to the drivers side strut tower.There is also a module inside the air box but I'm not sure what that one is.
On my other post about the bouncing I did notice when I put the spare tire on to see if it was my tire causing the bouncing i did notice that rattling sound wasn't as bad.Maybe the messed up tire is putting strain on my control arms and bushings?
