BaaaaaaaaaaaI would like to be able to lock the differential without shifting in to 4x4, but my switch/knob won't allow it. Do you suppose that is as easy as altering the switch?
I can lock my rear differential whether I am in 2WD or 4WD by pulling the knob. It still disengages at around 20mph (I typically only use during winter when snow is on the road).Mine works the same way, just pull the knob out. I also have 4 auto maybe the ones without that option have to be in 4wd?
