I seem to be having trouble unlocking my hubs on my 79 k20. My truck has a 350 goodwrench crate motor, 350 turbo transmission (th350) and a 203 transfercase. For some reason when I go to unlock the hubs, I put my truck in neutral, shift my tcase in neutral and get out and unlock the hubs. When I get back back inside the truck I shift the transfercase into H range and shift the column into drive but it doesn't go into drive. Maybe I'm not understand all the way about the hubs or the 203 tcase . Is it ok if I just keep the hubs locked in all the time? Will it cause damage? Thanks for the info.
