The hub assembly need replacement it sounds like. Early signs before you start actually hearing noise from the bearing.

Your best bet is to replace with a Timken unit, part #: 513137

what if i pop the wheels off, and shake the hub to see if it is worne out and has play to it?

alos if i unplug the sensors and clean them up and check the wires for anything disconnected or broken? if that doesnt work take it to a shop and have them read the codes?????

you can try that, but if the problems persists take it to a shop to have the codes read so that you can figure out which is the bad sensor and replace it. when you take the wheels off inspect the wires from the bearing to the plug, i had wire break between the hub and harness. other than a shop i don't think anyone reads abs codes for free in the pittsburgh area.

ABS codes are stored in the BCM, and a regular OBDII scanner will not work.

Don't take the wheels off, leave them on, and check for play. Better yet, secure the car, jack up the front wheels, and put the car in drive and look for excessive play as the wheels spin from idle. That's how I pinpointed my right front hub going bad.

Like I said, this is the early signs that the sensors are going bad. Nip it in the butt and replace the assembly now, before it start to make noise and affect the ride quality.

The bearings are starting to lock occasionally it sounds like. Mine never did that, but I got a nasty hum and vibration from the right side at speeds above 40mph.

Thats what both of my front wheel bearings did when they went. and when the shop replaced them, to turn the bearing by hand i was almost not able to turn them.

lol i got the same problem right now. ;crap

also if you jack the front of the car, turn both front wheels to see if they spin freely or if they are hard to turn.
