disco 2 help me :(

i recently noticed a gear noise coming from the front end when turning (like a knocking noise) and experienced a knocking through the steering wheel. I've learnt the hard way as my diffs given up tonight whilst towing my boat. the front diff completely disengaged and i lost all drive, due to it being an open diff? so i managed to get it the 3 miles home gently in diff lock.

I'm very new to the land rover scene and now intend to keep an eye on all my fluid levels because i don't want it to happen again.

anyhow, i own a 2000 D2 TD5 manual. what oils and quantities do i need for the diffs, gearbox and transfer box?

also where are the filler caps for the gearbox and transfer box? i can only see the drain plugs.

what diff do i need to look for? do any of the diffs from the 200 or 300 fit? does the front diff comprise of 2 half shafts? if so is it worth changing the shafts at the same time?

the donut on the rear is also wearing, is it right that i can change this for a flanged 200tdi rear prop? which will in turn rid the stupid donut?

i also i have a knock from side to side on the rear axle, could this be that the 3 bushes/bearings in the watts linkage are worn?

any help would be much appreciated

my discos been awesome up to now

cheers

Sounds more like it's just the CV joint that's gone, losing drive .. the clue is the knocking when turning ...

noise cv perhaps ,just under 2 litres per diff and 3 or t/ox filler is on rear behind hand brake cable 1/2 inch drive ,gear box t55 torx bit half way up side of box above drain

i dropped the oil in the diff (well what very little was in there) and most of the teeth from the planetary gears came out with it. are the cv's part of the half shaft on these?

OUCH and yeh they are.
