I just got back from the mountains where I did a little 'wheeling'. On the mountain road up, it was a bumpy gravel road. Driving down the road, I heard a rattle coming from the drivers side front. It sounded almost like it is coming from the wheel. I have auto hubs (I know, I am changing them out soon). Has anyone ever had this noise? I tried to 'shake' and pull everything underneath and nothing is loose. Any ideas? GSB Forever #3!!
