First Winnipeg winter with my 98 Suzuki Carry DD51T. No diff lock. Every single feature works, no leaks, squeaks or grinding noises. I'd like to keep it that way. My question is, can I engage 4WD on the fly? I've looked online everywhere. Only one post suggested that this is a possibility, as long as you have already engaged the axle lock. How about disengaging 4WD on the fly? The reason I ask is because with my Ford Ranger, I found that I needed 4WD at a slippery intersection but when I got to pavement I disengaged. We had some snow last night. Right now I am driving around with 4WD since the roads are covered with snow - and the truck is doing great. But once the city starts to tidy the roads up I wonder how I should drive. It would suck if I needed to pull over to disengage. Thoughts anyone?
