Hi all new here but I have a problem! I have a 96 blazer and I was coming home snow flying in 4 hi had been driving in for about an hour around 60 mph and the front end started making a whining noise that got louder the further I drove and i could feel it slowing down like it was dragging then all of a sudden it made a loud grinding noise followed by a loud clunk and now when I put it in 4 wheel the front end end makes a grinding noise but it seems to be slipping.Im thinking it might be a bad cv but not sure any help or suggestions would be helpful. All ball joints and hubs are new. Thanks in advance Dean. It also has 229000 miles on it.
