HELP! GA GT1 Problems

I have a 2002 GrandAM GT1 and out of nowhere I started getting the ABS, Trac off and Service Engine Soon light on. It's sporadic, for 2 days it didn't come on then now it is on most of the time I drive it. I read some of the replies on the board something about the hub bearing? I went to the dealer and they charged me $280 a piece! It's not on yet -- anybody know where I can get it for cheap? Help! Anybody else had these issues and was it the hub bearing?

Yes it sounds like the Hubs/bearings are going out.
I hav changed a few on my GAs, and other peoples GAs and Aleros.

That seems very high on thier prices.
You should be able to find them cheaper(around $110 each) at a local parts store, price just depends on where you go to get the hub/bearings.

Heres some prices
