ok, well i've just lied underneath it playing. I dont have freewheeling hubs / ones i can lock / unlock, just standard ones. So i cant try that trick.
2wd, the front shaft will spin freely underneath (obviously as its not connected to the gears)
4wd, i stuck a screwdriver in as you said wezzlegod, and each slight turn either way moves the car front/backward. Which tells me it is connecting up to the gears up front :S ( Both sides of the front diff spin too )
Yet when i drive it on the road, usually in 4wd, my steering is tougher / limited (i dont have powersteering). With the occasional clunk from the cv joints. Now this doesnt happen with it being as easy as 2wd.
Is it possible it could be in 4wd, untill theres some force, then it just not work fully?
And i still cant change between 2 + 4 whilst rolling in a straight line.... i get a loud crunching
Magiccat: Living on an island we have lots of slipways (concrete slopes onto beaches / the sea ) at low tide, you can drive up the side of them, which is a nice challenging steep cobled slope, with a sharp concrete corner on the top. I crawled up one, and bottomed out the chassis on the top, not that hard (have hit harder without a problem) and SNAP, something went, now i have these problems :S
Usually i wouldnt have been so silly, but i had landrovers challenging me, which makes the whole situation a little emabarassing
haha
Thanks for the help guys, still in search of the exact problem tho...
