hi, from what I can see only the yellow line on the right is of interest ( the one underneath the "AT" in DAIHATSU. If your VCU is not totally siezed,, that line should split at the point where the input shaft goes into the VCU body--- everything else is rigid.After you put it back on yer real motor.
mark it up where ive indicated with yellow lines then try it agen !
Can confirm Willo is correct. Some peeps advocate puting a bar in rear UJ of prop shaft to test - however, and especially if manual gearbox, NEVER go underneath relying on jack only and even if on axle stand, both front wheels should be chocked front and rear of the wheels to prevent movement as turning the rear prop even with a good VCU will want to cause the engine to turn over and hence the FL will want to move!
Hi, Endorse your sentiments wholeheartedly.--- Given the pain it is to split the UJ's from the VCU, cant imagine why you wouldn't just drop the whole lot, front & rear props, VCU and all, and separate it on the bench if need be! All the talk about the VCU being dangerously heavy, seems a bit extreme to me. Supporting front and rear ends of the props and lowering the VCU on a trolley jack is quite straightforward (made up a little wooden custom cradle to stabilize the vcu)I've just done me own VCU and found it surprisingly straightforward. Few bits from this experience:
.
I supported the ends on old flowerpots(!) then used a jack to support the VCU while I undid the bearing carriers & dropped the whole lot off.
Old VCU is a sod to get off the props - undo the bolt a bit (ring spanner & hammer action), then use some sort of tapered bar to force it off the splines. I found an old chisel did the trick here - had to keep making small adjustments in the bolt to get the correct leverage.

Get new support bearings & find a friendly local engineering works to press them on for you - I got charged a tenner, better than using good old-fashioned hammer & socket method and buggering £400-worth of new VCU! And for the sake of £40 you might as well have new 'uns
I found the new VCU surprisingly hard to turn, so I'd definitely say use the bar in the prop method to test the old one. You won't even shift a good 'un just by turning the rear wheel by hand IMHO.
Use a T12 Torx socket (I think that's the size) for the CV and diff joints. I found a good selection of UJs and extensions in my socket set were invaluable. If you don't have the wherewithal to get all 4 wheels off the ground (like me - only 2 axle stands to my name), undo the front joint 1st so you can rotate the prop to get at the back bolts.

New bits from Island 4x4, nailed it all together with plenty of threadlocker and back on the car.
Now it feels 'right' again. Main symptom was a binding sensation on full lock which has now gone completely. Feeling v pleased with myself after local dealers said "<sharp intake of breath> it's yer IRD mate, we'll sort it for a grand...". Saved meself £600, well worth the grit in my eyes (wear goggles underneath!) and aching back. And lotsa brownie points from the missus whose car it is.
Hope this load of blather is some help. No doubt veteran spanner-monkeys on here will correct me if I did anything wrong...
its the supporting bearing thats gone
yes but they look hard to get off and onthats good news - its cheaper
i have had the prop on and off 2 times over the last 2 weeks with no probs only having this prob after changing the bearings , any ideas whats going on ? i have knocked them off and put them back on the right way round just need to refit the prop after the football and test 
As landyzone has just saved you hundreds of quid ... are the drinks on you?
Cheers
yes what u have'n
