yo,
In my 96's Workshop Manual, Ford only says this about da BW 1356 Transfer Case Shifter ****;
"Prior to installation, the gearshift lever **** must be at room temperature and may be warmed to 60°C-82°C (140°F-180°F) as an assembly aid..."

I never took it off, but others have said it is pressed on to the splined shaft. And use a hairdryer to soften it for removal, exactly as Ford describes for installation!
