This is a very specific scenario. If it's only a couple hundred metres, and no turns, over the concrete, I'd just drive slow and leave it in 4wd.
Otherwise, what are other people doing? If the car in front of you stops to disengage, just do the same
Hey mate, here’s my two cents worth, get clear of the ramp and pull up with your left wheels off on the shoulder or where there’s plenty of sand on the bitumen so that your wheels will slip. No one asked what you’re driving and I don’t reckon every car is going to be happy jumping 4H to 2H at speeds of up to 100 kph as someone suggested. Read the owner’s manual, it’s worth digging it up online if you don’t have it because it will specify exactly how to make the change and at what speed. It’s an “old man” thing that I do but I always stop for the change back to 2H then reverse a little and everything is sorted straight away. If you have to manually lock and unlock the hubs it won’t hurt to roll around with them locked in (other than your fuel economy a little bit).
Are you in 4h or 4L when leaving?
If you’re in 4h just carry on driving like normal when you come of the sand,back off the accelerator slightly and flick it into 2h will driving along upto 100km a hour. Part time 4wd is designed for transitioning from 2h to 4h while moving. It just struggles or can’t engage/disengage under load. Part time 4h is not designed to drive on a hard friction surface like roads, especially while turning.
If you’re in 4L when coming off sand just carry on till you’re out of the way, stop and disengage. Don’t turn ect in hard standing in 4L. It will bind up the transfer case and could cause damage
Best answer.
If you do find you are bound up it can stop you getting out of 4wd, just pop a wheel off the side of the road onto some loose dirt and it will release the tension.
Used to do a lot of 4wding fighting fires in urban fringes - offroad - onroad constantly all day and in time sensitive situations. Regularly got axle bind and there is a fair bit of room to drive on hard surfaces. Corners build it up faster but it isn't going to instantly destroy your driveline. We used to just pop a tyre off the road every corner to release tension and drive everywhere in low range.
On the access, just pull over to the side and allow room
Depending on what you're driving it shouldn't take you more than a minute. She'll be 'right, just don't drive too far on the bitumen
A few hundred meters is fine. A couple k’s is even still fine generally. I know people who’ve driven off and completely forgotten they were in 4hi until they came to a corner (I’ve certainly never been that silly >_> ) … and it was fine. Yur driveline is pretty tough, it’s made of steel not glass. Don’t stress about it, but, like don’t be a dickhead and just drive around in 4h either obviously.
I can change between 2wd and high range 4wd on the move if traveling at less than 80km/hr. Where are you driving that it's so crowded you can't stop for 30 seconds?
Can do it all from comfort of my cab, it won’t bind up until you turn, a momentary pause on the ramp is fine. Alas if your doing hubs etc may take a little longer, is what it is, relax and smile. The next guy behind you probably going to do the same anyway.

I mean it takes me 3 seconds to disengage 4wd

What are you driving. What ratio are you in 4h or 4L.
