Sounds like you might have found your problem then. Maybe you'd better get it checked out by a gearbox specialist?

Might be worth calling ZF Netherlands and seeing if they have any approved workshops near you. If I were you I'd be tempted to go here:

i cant believe the play is caused by the driveshaft/cv joints itself looking at the pic.
think its caused by the axle which goes into the box.
i know that axle has a bold visible when removing the inner cv joint, and see from there...?

Is that the side where the play is?

It's got to be worth a look at that bolt then. If it's loose, the oil seals will probably need replacing and the level checking, but it doesn't look like a complicated job.

yeah, i think on full lock to the right i can loosen/remove the inner cv joint without having to get the whole axle out isnt it....?

...from other forum...
I'm not sure what causes it, but I'll bet you've got a lot of play in your output flange coming from the front diff. Passenger side, correct?

Chances are that your bearing is worn (root cause or a symptom? I'm not sure) and you need to replace it along with the necessary shim that goes between the front diff case ans the outer race.

I'd recommend replacing the entire bearing, so you'd need to remove the front diff and have the inner race pulled of and then the new one pressed on. The shims start at 1mm thick and are available in increasing thicknesses by 0.1mm. I'm not sure how you measure for the correct shim thickness, so you might need to buy a few of them. Think they were like $16 each last I checked.
If you can't go to the track, bring the track to you.

...was wondering how to see/feel play when nr9 has been removed to determine which bearing is shot...?

Number 2 and 11 looking at the picture, good luck with number 2 although saying that you might be lucky and get away with shimming them.
