I have a farm truck that I use the 4wd only on the farm. It has quit shifting and my mechanic can’t track it down. Can I shift it manually under the truck for the few times per year that I need it. I recognize it’s probably a pain but it’s worth it not to have to sell it and buy another working 4wd because we just bought a ‘22 Maverick 4wd that is my wife’s truck and my dirty old banged up f150 engine, etc. is good.

Thanks
