why not just use the centre nut? dont make things more complicated than it needs to be.............. K.I.S.S

that might help in removing the old fluid - rotating one end relative to the other.What I can tell you is that 'working' the VCu does provide a loosening effect. Having taken the old fluid out of one and left it standing in a tray for a few weeks it is pretty solid now. It is a bit like 'blue tac' - if you work it and pull it about it gets softer (opposite to some other things )..................
But reducing the amount is unlikely to affect stiffness - it may provide more room for the stuff to move though.
That does tie in with the torque test curves performed on couplings - ie as it slips it gets less viscous. If you were to stir it in a air tight box with a small air gap - you'd notice it getting softer until you stirred it more quickly to a point when all of a sudden you'll hit "hump" mode!What I can tell you is that 'working' the VCu does provide a loosening effect.

Working a stiff VCU may loosen it up a little. More efficient is heat. Put the unit in hot water and the stale silicone will come out a little easier afterwards.What I can tell you is that 'working' the VCu does provide a loosening effect.

The bearings may be good - but you've got to get them (or at least 1 of them) off to drill the VCU straight - that may render it u.s. I think mine managed to survive the trauma, but the dust shields definitely didn't - I don't know yet if they can be purchased separately. Nodge did put up the spec for the just the bearing component of the support - for if the rubber is all OK, but the bearing is shot. Not sure which thread its on.Okay, guys, the shafts & VCU are off. I've driven it and it handles extremely well. I can tell the back-end is lighter but doesn't seem to cause any problems with handling or cornering.
I'm now looking to carry out the VCU repair. The bearings, by the way, are perfect with no play or suspect noises. I may not replace them, but then again...
The rear-diff pinion oil-seal with be renewed as I progress. I'll need to get a 28mm socket for that job.
I also informed my Insurance Broker of my temporary 2 WD, explaining why. They say it's okay and wished me luck with the repair. I'm covered.
I'll give an update to all of this as things happen.
I'm off to have a shower with Swarfega... I think that's her name. lol

That's a really great picture of the bearing, very helpful... but also the background. I'm guessing that's manmade concrete, with a hell of a LOT of quartz in it. Very interesting - geologically speaking.

Nice one Andy, sounds about perfect. I have another one to do soon and plan to use your methods. Any links to where you got the bolts and pipe adapter thingys?So - my refurb VCU is now fitted with new GKN bearings and all seems to be working well.

Drives and tight turn reverses as it should.
