I've heard you can do it no problem in our trucks - i never have and hopefully won't ever have to. I think it's just looking for problems. PLEASE post a link to the shifting thread.
I only shift into 4x4 from N or Park. I also go in reverse a bit after i shift from 4x4 back to 2wd(2hi)... not sure you have to with our trucks/np205's but i've heard you must go in reverse for some trucks (toyotas?) after u go back into 2wd.
I havent been in 4x4 in tooo long (Esp for having a blazer!) , besides for completely rebuilting/getting new hubs... is there any thing i could spray in them before i go to flip them? I don't know that i'll have any problems, but i wouldnt be shocked if i did, and i'm just wondering what's best.
