fezzy192:
i think the viscous coupling is seized in the tranfer box
i have jacked up the back axle and put in neutrul and tried to turn the wheels and nothing wont move
whats my options

change i change the transfer box for a manual difflock ???

Bowie:
Which neutral? The transfer box in neutral or the gearbox...... someone made me think mine was shafted when I couldn't turn the wheel, but then reading Ashcroft Transmissions site it was clear it was the transfer box that should be in neutral, and not the gearbox....

Lookie here: Ashcroft Viscous Coupling

If it is screwed, a new viscous coupling is £270 from Ashcroft, which is probably the medium-cost way to go about it, or a new transfer box is ££££s... or a second-hand unknown one will be next to nothing :)

HTH,

I bought my Rangie for 560 quid.  The viscous coupling had seized when I bought it.  It as advisable to get it sorted pretty quick as it can damage other components.  However:-  as I did not use it for my daily drive I just kept on looking at ebay.  You should be able to get one on a "buy it now" for between 75 -125 quid.  You may also be able to get one for less than that but it may have the transfer box or gear and transfer box still on it (so you will usually have to collect!).

I got a transfer box c/w coupling for 19 quid (but I think I was lucky).

I was going to change the complete lump but in the end just took the coupling off as I was working on my own on the drive.  It was a bit fiddly.  I had to take the prop shaft off (you can get to all the nuts on the front of the shaft but not on the coupling end as you cant turn it (as it is seized!)) and also the gear box cross member came off (unbolted and just hammered out of the way rather than OFF).  Their was a bit of swearing going on but only me to hear it.  Also remember some of the screws will require imperial spanners etc - I think I used an imperial ring spanner at one point - but luckily had a few hanging around.

But I did it and I ain't no mechanic.  Oh – and as such I can’t say that my way is the right way!!

Good luck mate!

if back axel is off ground and u turn 1 wheel should the othe wheel not just turn oppersit way and get no movement to gearbox

ChrisV8:
You can change just the viscous as others have said. It's not difficulyt just fiddly as you have to take off one of the gearbox mounts, it's bolted to the Viscous unit housing. Getting the propshaft off can be a pain but using a Difflock propshaft socket makes it easier.

Alternatively yes you can put a manual locking transfer box on but you will need all the linkages for that and time to mess about putting them in.

You need to check if it's seized by looking at the Ashcroft link, it mainly works through the front axle so thats the one to lift and try to turn. Get it sorted though, daughter drove hers for too long and took out, propshaft joint, and cv in the front axle, it turned the shaft in the cv and I cannot get it apart it has welded itself together. Shaft cost about £300.00 !!!!! I also have just bought a Rangie with goosed viscous that has taken out the chain drive so it is undrivable.
