L200 4wd issue?

[Con]

Any advice?

I have an old L200 4x4. I have always assumed the 4wd mode was working. When l engage it, the engine sounds different and l always thought it was working. Last week though, when l actually needed 4wd it felt like l didn't have it. Didn't actually get stuck, but how can l test if it is working?

Thanks, any advice appreciated

drive it into a muddy  field and stick it in 4L, engage 1st gear and see if one or both of the front wheels is spinning?  Does the front axle have manual hubs that means you hafta get out of the truck and manually engage them first loike?

That was my plan. Then I thought, with my luck, I'd get stuck! It is the model which you have to manually lock the freewheel hub. Suppose i'll just have to go for it! I'll get the tirfor out incase

trolley jack up rear wheel and see what happens

So if it falls off the jack the front wheels are working?

Just chain it to a tractor and which wheels turn.

Ok thanks everyone. Definitely not going for the jack option, haven't got a tractor, i'm off to find a muddy field. I can see the suggestions getting more ridiculous on this one ?

Check your free wheel hubs are locking. Lock them whilst in 2wd and get underneath - you shouldn’t be able to turn the front prop shaft by hand if they are both locking correctly.
