IFS front diff problem.

IFS front diff problem.
When driving my lux down the road this arvo with the hubs locked I could hear a bit of a clunking noise coming from the front end. So when I get under and have a look tonight I thought maybe I had done a CV but the flange that comes out of the diff on the drivers side has heaps of movement up and down.
Does that mean I have buggered a bearing or something in there?
It still seams to drive in 4wd OK but makes a bit of noise sometimes.
I was hoping to go for a drive with the Perth outerlimits crew this weekend but it looks like that might be a bad idea .
So can anyone help me diagnose my problem?
The SAS is looking a better idea every day .

The drivers slide flange will move around heaps, up and down, side to side. This is normal. There is no bearing on the drivers side.
As for what could be wrong with your diff, Does it only make a noise when its under strain???
I need to SAS badly, my front diff is still currently buggered, another crown.

I broke 2 cv`s before a centre and that was a 4.8 with auto locker just lucky i think,The centre will bust cause all the strain go`s through the one centre and then to each cv.My cv`s broke each time cause one wheel was in the air

Well I ignored the slight clunking noise and went wheeling today and after the first hill climb the clunking turned into intermitant banging coming from the drivers side that is savage enough to be felt in the steering as a jerking feeling. Had to do some 2 wheel driving with the rear locker.
But its all good caus I have bought a solid front diff this weekend .
Now just need to collect all the other bits I need and get stuck into the SAS.
HG if your front end was for sale a month ago I would have said "SOLD" but now I will say "SCREW IFS Im going SOLID".
How much are you after for it anyway?

Havnt had a good look yet.
Its my daily driver and its driving fine in 2wd so I probably wont be in a huge hurry to rip into it.
And I wont be fixing the IFS anyway. I will be collecting bits for my SAS.
I will post up when I look into it but it wont be for a bit.

Oh well that means I can sell my CVs when I do my SAS as it isnt them that are buggered.

Told ya's!!!!
Someone asked "why would the Crown wheel and pinion bust all the time and bust before CV's"
Well with all IFS luxs the backing plate for the Crown wheel is very thin!!!
As a result when under load the pinion pushes the Crown wheel, and since the backing plate is thin it causes the crown wheel to flex away slightly which then meens that the pinion is driving on the outer parts of the teeth. I hope that makes sense!! By driving on the outer parts of the teeth it causes them to chip/crack and eventually break off!
You will notice that if you ever speak to some one that still has the IFS but they have installed a ARB or Detroit locker, that they will not be breaking Crown wheels. This is due to the fact that the ARB and Detroit have the backing plate as part of the locker and is quite a bit thicker in design, this cuts down on the flexing and thus cuts down on the broken C/P. They would now however be busting CV's!
After fitting a front ARB locker I have never had a crown bust.
Did two in the open diff .
I have never had a CV let go with the locker (in) as power is spreed
even across the two wheels.
Mind you if you don't drive em right with front locked it will bust up a CV.
I think most comon CV bust is when one wheel is lifted and speeds up,when it comes down BANG CV or Crown.
The good part off the locker is wheels stay at constant speed.
