Hi guys. I need input. So far within a year, both of my front wheel bearings have completely fell apart inside the hub (2nd on was recently)and I am still having problems. When im driving, there is a vibration and kind of a tapping that i can feel in the floor board and in the pedals. Same feeling i got when the first bearing fell apart. It isnt a constant repetative feeling, nor is it from the road. I have driven over roads and its felt really rough and other times over the same road, its smooth. I have also had both differentials flushed and filled...thinking that may help but not soo much. My truck is a 2003 Ram 2500 with no suspension mods. All factory. Any input of what this could be? I do have atermarket rims and tires but since it doesnt seem to ride rough over the same roads all the time...I kinda ruled them out. Any ideas would be greatly appreciated. Let me know if yo need any other info from me.
