Dear hipo1024,
I am very grateful for this advice.
As I have hardly used the 4wd, I can only imagine that the damage has been done by previous owners. In fact it was my wife who rang to say that she was experiencing this problem when she was out in the snow with it collecting on of our children and she was driving on mixed surfaces.
It did post when it happened and had several replies but you are the first to offer an explaination as to what could be wrong.
I think that there should be a big notice on f.o.g. to tell all new owners the limitations of using 4x4 on dry roads.
In fact my wife was on mixed surfaces and I have to say that I am dissapointed to find that its not easy to use my frontera in the very conditions that I assumed it could be used in, that is to say icy patchy roads.
However, I also found out from f.o.g. for the first time recently that after stopping initially to activate the front hubs it is possible to change in and out of 4x4 to 2wd while on the move. So this is what we have been doing on patchy surfaces and it seems to be the answer. I also have been conciously driving with one wheel in the slippery bit as usually is the nearside which have the snow or ice. I didnt experience any of the jumping out in my old 2.3.
At the time it shook my belief in fronteras as I am under presure from landrover owners that I know and I didnt realise that Discoverys are in permanent four wheel drive and this is presumably why they can tow three tonnes on a dry road.As Discoverys do 30mpg the same as my 2.5 and they have 7 seats it has made me re consider what to have.
The thing is, I just like my series 1 lwb fronteras.
Is there anything I can do to repair my transfer box,could it be just one part worn out? or relpace the front axle with a rear diff ?(this would be mad ) .
Thanks again for posting I really appreciate it.
