When i got home today got out of my truck and heard a noise and got down by that disc brake area and flet the wheel and it felt like there was somthing still turning in the axle but most what i was asking about is my brake was burnign hot and the inside of my hub is melted ( the plasic nob to engage 4x4 i mean) and my wheel also is just really hot probably from that????? What do i do
