is there any way of testing to see if its that cheers kev

andyb:
An IRD usually fails because the viscious coupling in the prop shaft has seized. A Freelander can be driven without the prop shaft and it's a good way of finding out if the IRD is making any noise or not.

Also you can jack up the front wheels and remove the IRD filler plug. Look in and you will see the teeth of a gear. Turn the drivers side drive shaft and you should see that gear move. Any diagonal movement in that gear means that the bearing has collapsed and the IRD is toast.

A replacement IRD will cost from £700 before any labour charges.

Llanigraham:
If the IRD had seized/failed then the vehicle would not move.

Check the condition of the VCU support bearings and the rear diff rubber mounts.

To check if VCU is seized:
car in 2nd gear
handbrake off
jack up one side so 1 rear wheel off ground
put socket and long breaker bar on that rear wheel centre nut
lean on breaker bar

If it moves slowly and smoothly with a fair bit of pressure then VCU is working.
If it wont move at all, then ducked.
If so remove VCU and prop before you duck the IRD and run in front wheel drive only. This will not damage anything!
