Yes you can, I have done it once at about 20 mph, in and out of 4WD. O
Having done it once I will never be doing it again. It was too "mechanically unsympathetic" for me.But have a go, nothing should break.
Remember to only do it on ground with reduced traction, its not for use on grippy tarmac :)

I do it every day whilst moving at speed and have done it at 60mph more than once. I've also done it on grippy surfaces, while turning and in conditions when the rear wheels are already spinning slightly. Every time it goes into and out of 4wd quite happily with a reassuring clunk-clunk from the front hubs.

The only time it's made any complaint is once when drifting on a stubble field very sideways with the rear wheels going possibly 20mph faster than the fronts I thought 'I wonder what will happen if....'. I pushed the lever, the dog clutch in the transfer case banged a couple of times, struggling because of the speed differential, before engaging as normal and all 4 wheels starting to spin. It has continued to work reliably every since.

If you have the older model with the gearstick for the transfer case, with a little bit of practice you can also switch between low and high whilst moving. I do that most days too.

I've found it to be a robust and very convenient system and I suspect the few issues people do experience are most likely caused by infrequent use.

Someone else will correct me if I'm wrong here, but I'm sure if you are engaging/disengaging 4L that you should be stationary


IF IT AINT BROKE, KEEP FIXING IT UNTIL IT IS

I would not recommend changing into low gear at speed.
I done this while sliding forward with brakes locked sometimes but then it is kind of stationary..

Beware it would not be smart to change between 2wd and 4wd if you have manual hubs and have forgot to engage them.

Second that with the infrequent use especially with the vacuum system. The hubs will not give you any problems with frequent use and lubrication. The same with the push button transfer case.

I too regularly engage front drive on the go though with my manual hubs I need to know in advance that I am likely to need to do so and have them pre engaged usually towing trailers in and out of fields or if snow is forecast.

On the electrically selected gear-changer, I have more than once inadvertently selected 4wd (while at speed) when not looking down to move the air recirculation slider, only noticing when the glancing at the instruments and seeing the 4wd light on :unsure:

Yes you should and Suzuki insists that you are stationary. However, with the manual transfer case and a little bit of practice it is possible to do while moving. It's non-syncromesh so you need to rev match, much like changing gear in a vintage car.

That's "double de-clutching"
On non-synchromesh boxes (found on many pre-war cars) the procedure is:
Clutch pedal 'in' to disco the engine from the g'box, move the gear lever to the neutral position. Then with the clutch pedal 'up', rev the engine in neutral slightly trying to match the rpm for the next gear, clutch 'in' again and select the next gear, clutch up again, and away you go

...takes some practice to do it nicely without crashing the gears :blush:
