I got a 98 GTP that my ABS and Trac off light just started going off together last week once or twice now in the last couple of days its been on almost right when i turn my car on and start driving....I hear no grinding or anything abnormal when im driving/stopping. I just had my front tires remounted and rebalanced last tuesday because they had rim leaks and were shaking while driving at high speeds.

I have heard that it could be a bearing which my buddy who is a mechanic while doing my tires last week said it might be a bearing but he wasn't sure because the side that he noticed had play while moving tires up and down was the same side we replaced the wheel bearing last spring....

so any input?
