I am new here and a new owner of my jeep 2004 gc limited.. I started hearing a loud roaring noise in the front left side of my jeep, it seems to goes away when i exhilarate, but immediately returns when am at cruising speed. It also seems to dissipate after driving on the highway for a time period. In the morning is very loud and evan louder when its cold. I would appreciate any input or advise to help trouble shoot this.
