Hey guys I had a very strange issue. 02 Tahoe with 180K on it. Other day going down freeway I kicked it in the ass to pass semi rig, all of a sudden I get a Growl out of the left Front wheel. so first thing I think is wheel bearing hub asssembly. I put a new one in 6 months ago, NP under warranty and replaced it again. WTH, I still have the noise. Take it to mechanic and he say front differential is out. NP call up a buddy and we swap that out, what a PITA that is. I still have the issue. It is a very loud Growl like your running on the rumble stripes on the freeway. So I'm looking for input if anyone else has had this trouble. I looked at the other wheel bearing and that is quiet and smooth. I'm thinking Next Maybe a U-Joint, since it came on when I kicked it down and put torque on it? Running out of Idea's, pleas help.
