the pulsating feeling went away once i changed the rotors, however say im going about 30+ and stomp the brakes, the car stops fine but i feel the abs kick in even though its dry and the road is smooth,

possibley thats it, the extra heat from the friction of the old rotors caused it the bearing to go early

 

thanx for everyone input

 

I'm sorry, but I'm not buying into the "warped rotor trashed the bearing" theory at all. The center of the rotor mounts to the bearing hub, and the wheel mounts to that to make a nice sandwich. A warped rotor would be warped on the disc portion, beyond where it mounts to the hub, and will have no effect on throwing off wheel balance, etc. All the warped rotor is going to do, is make the caliper wander in out a little, but the caliper will be sliding back and forth on the caliper bolts (that's why you feel it in the brake pedal). Will that make the brakes run hotter, possibly a little.....maybe. Will it cook the bearings, nope! It's quite possible you just got a defective bearing hub assembly, it happens.
Also, when you stomp hard on the brakes, the ABS is supposed to kick in. ABS=Anti-lock Braking System. It's supposed to keep the brakes from locking up, what happened to you is normal.

 

hmm you got me thinking now, cuz thats a good point and makes sense too. but the damage is done and i`ll be on the llookout for a new hub bearing soon

 

If this bearing is only a few months old, I believe those have at least a year warranty, so you should be able to get a new one for free.

 

I purchased it from rockauto, will give them a call and see what they say.

 

just made it in time-- w00t!!
