I had thought about that. The one bolt that I could see wasn't backed out when I looked but in all honesty, the noise did seem to come from that area. I'm not running a dust shield so if there is a bolt that's hitting on something, I'm not sure what. I may get underneath and have the wife crank it and check all four. I put all the bolts in with locktite and torqued to the specs that I read on here. When I torqued them I thought that it didn't feel like that was a high enough torque but went with it anyway.
