I’ve been working through the various corroded components on my rig and found the 4 H N L Lever is “stuck” in the 4 H position. I mentioned this earlier and folks pointed out it probably needs a bit of PB Blast and some force. I’m sure it’s never been engaged - Question - once I let the PB work it’s magic I plan to place a piece of pipe on the lever and tap it liberally. Should I have the truck’s transmission in N as well? Could I potentially damage anything? I have located the lever at the transfer case, should it move freely once de-corroded and lubricated?
