Whining Noise From Front Diff/transfer Box!

[Buckyuk]

I have searched on 3 or 4 skyline forums and cant find the answer to my question so hopefully someone can help on here.

In 1st 2nd 3rd 4th gear drives fine no noise.

In 5th gear there is a loudish whine from either the front diff or the transfer box, sounds more like the front diff.

Right heres the funny thing. In RWD it never makes the noise, it only makes the noise when load is being transfered to the front wheels. And only does it in 5th gear when power is being transmitted to the front, i.e accelerating (gently or hard)

Any other gear it doesn't do it, no matter what load is applied.

I chanegd the oil and the magent was full of bits, the front diff is clicking on full lock turns now. Time for a new one me thinks before it pops.

quick question do you have to pull the motor or could you hold the motor up and drop the cross member and pull it off that way, or ends up taking longer then just pulling the motor?

I'm just going to drop the subframe, easier than takeing the motor out
