Hi, what is this? the part i circled in the red. the p=art with all those lines going down it. the one on the other side is broken, and make a wierd noise when it moves. what can i do to fix it, or replace it?

 

Where on your car is that?

EDIT: If that's your brake disk and axle, maybe the ABS sensor is hitting the wheel speed gear thing?

 

looks like he's looking down on a brake rotor...

 

On second thought, it might be a rear brake rotor and hub. So yes, it could be the speed sensor hitting the geared wheel.

 

yes, it is the rear brake rotor and hub. that piece seems to be hitting something since it is cracked and making this wierd sound. also my brakes r really wierd for the first 2 min the car is on, where is clicks and doesnt wanna brake too well, and u hear this clicking sound inside the car, then all of a sudden, the sound stops and it works perfect again. could that be causing this.

Remove the ABS sensor from that wheel. Take a better shot of the cracked part, because there doesn't seem to be anything wrong here.

 

thats not the cracked one. the other side is, i just couldnt take a good pic of that side. basically it is cracked from the hub towards the rotor. and it is pushed back towards the hub more, causing it to rub.

 

from a distance it looks like a roller bearing - not saying that it is - but doesn't the hub have a roller bearing inside of it..............
