Hi I was referred to this forum from a trailblazer forum. I have a 2003 tb ext lt 4x4 and recently i started to hear a humming noise like a bad tire coming from the front. You could only hear it when over 40km/h and whenever I would turn right it would get a liltle louder. So I thought it was the front driver side wheel bearing so I went and purchased one and changed it myself like I did in other cars before, I torqued all the nuts and bolts to specs and after it being all done the noise is still there the same as before! Could it be something else or could it be the passenger side bearing? Thanks
