I will do in the morning, i guess the same as trying to turn the wheel ? Should i be able to move it slightly with a lot of force ? Thanks

It should turn slowly with a constant pressure on the bar, there is a torque figure but I cannot remember what it is. As long as it turns, it's OK.
If it's locked, it may have destroyed the front diff, so while you are under the car, drain the diff and look for bits of metal.

Apply 15 lb ft of torque to output flange nut for 1 minute flange should turn 25 to 30 degrees in that time.

Thanks again all, i will get under the car in the morning.

Good morning & what a glorious one it is ! I have tried to budge the viscous coupling, 1st with a decent wrench then with a 2 foot bar on the end, NOTHING ! It will not budge at all, so i am guessing the VCU is pooped ! I am hoping that this is the only issue, no debris in the diff either !! Thanks Elliot

Yep, time for a new VCU. I check mine at every 6K service

Try Ashcroft Trnasmissions.

If you can afford it I would recommend you purchase a complete remanufactured transfer box which will include the VCU. Your old unit may have bad bearings, worn pump streatched chain etc). Ashcroft do an exchange deal.

Hmmm, transfer box is pretty bomb proof assuming it has oil in it that has been changed this millenium. Unless there are oil leaks I'd leave well alone and just swap the VCU.

Thanks for all your advice. I'll just go for the VCU first as i am one a bit of a budget.
