Good ol Landyzone.
New guy asks a question, Someone (Grumpy Gel on page 1) gives the most pertinent reply and gets quietly ignored then there is 5 pages of bickering. Nothing changes.
Its clear from the original post that the guy doesnt know anything about his car - thats not a sleight against him, after all thats why he is here asking for help.
So he gets told to dick about in a muddy field, do handbrake turns, lift it in the air.....Not technically wrong advice, but pretty useless.
Given that he knows nothing about the car, he will not know how a freelander SHOULD behave, handle and react in various situations, has no idea of the capabilities of a working one and will not be able to tell much from how his actually behaves. At best he will learn nothing, quite possibly he will mis-diagnose something and given that he knows little about 4x4, is running Toyo T1 tyres and potentially only has two wheel drive, might very well end up stuck.
Lift it in the air? Yeah, that would tell him things, but just because some people on here can do that, doesnt mean everyone else can or should. I think you would be surprised at how few people have the space, equipment and knowledge to safely get all four wheels off the ground without going to a garage.
Or he could do the one wheel up test - takes minimal tools or knowledge, is relatively safe and will tell him more than enough about his car. OK, it wont show a difference between a free-wheeling VCU and a stripped IRD pinion, but given his knowledge levels it will tell him enough to be able to make a decision about what to do next.
And inevitably in a few days or weeks some other new person will sign up and do a search for help with their transmission, find this thread and ten others like it that are heavy on guesswork, opinions and rambling and light on facts, so they will ask for help, and the cycle continues........
