I have a 1992 F-350 cab chassis with manual hubs and 4x4 shift on the floor and I can't get it to engage. I lock the hubs, shift to neutral and I can shift to 4 Lo but not 4 Hi. The shifter says to "push down" but that doesn't do anything. Am I missing something or is something broken?
You need to have the vehicle moving straight ahead or straight backwards about 5 mph.
Not sure if it's like my '02 F350 with manual hubs and xfer case lever, but I've got to be moving a bit for 4wd to engage. Nothing like that satisfying "It's in 4wd dammit!" clunk when it engages..
