These problems are based on the broad problem of what seems to have been labelled "torque-binding"
I have found some information but still have a few questions:
1) can i simply disconnect the drive going to the rear wheels, I know there is a fuse somewhere which will do this? Where? I want to pinpoint the problem. Will this cause any damage if i drive with the fuse in / only in front wheel drive instead of AWD?
2) There is definately a shudder and hesitation when i turn corners slowly, its definately at the back. Will it be the rear or the middle diff that is causing the problems? I know its not the CV's as these have recently been inspected.
3) I am going to empty and change the oil in both diffs and the transmission this weekend in search of a temporary fix, is there anything else i can do?
My car is a 92 GX Liberty(Legacy) Wagon it is AT and has done 199,000Kms. I want to keep it for as long as possible, but am saving for an overseas trip and cant spare the $$$$$ for major repairs. This problem is the last thing i need.

If you can help or comment it would be much appreciated.
Thanks
