This weekend I was going to go wheeling. Up in the mountains I discovered that I could not get my cruiser into low range. I still have all of the dash mounted 4x4 controls, but the linkage moved fine when I disconnected it. I've had it be difficult to shift before, but normally a press or two of the clutch repositions everything so it slides right into low. What can cause this? Is the only possiblity the clutch sleeve and splines are damaged? If this is this case and only the sleeve is damaged, do both parts have to be replaced to match properly? It is a 1968 vintage case stuck to a 4spd, so I really don't want to throw much money at it. I am going to continue driving it until I have time to pull out the transfer case around thanksgiving.
