On my way home from work tonight, I noticed a violent BANG when taking a slow corner. When I got to the stoplight, as I took off from a stop, I got 4 or 5 more violent BANGS. When I got home, I could barely move the truck with getting these BANGS. Maybe rear end? I noticed last time I changed my rims, that I could move the axles in and out about 1/2 an inch on both sides. Is that related to this problem you think?
