Ive got a problem here, and cant figure out what it is. Ive got 325/60/18s on with a 2.5" level kit. I cant only hear the noise at low speed, due to the road noise my tires make. Its more of a clunking/grinding noise. I can hear it going straight and turning. I took it out in a parking lot, and just had it in drive and coasted around, and could really hear it coming from the front end. Could it be a bad wheel bearing? Ive always thought they made more of a squeel, Thanks for the help

 

Does it go away when you shift it into 4wd?
