Hi , I was out thrashing in the mountains today and I had a reoccuring problem of my transfer case slipping out of four low numerous times. When It slips I am under load and in need of it. Also a time where 4 high will not work at all(hill climb, Can't get enough power in 4 high to even let the clutch out). As it slips out into neutal I get a nice gear grinding sound. Before I dig into it , is it possible my linkages need to be adjusted. I have never done that before. ???? Any imput on this problem would be good to hear... oh ya and its a bJ60 with a 3b/h55f, Thanks in advance guys.
