my neighbour has a freelander diesel .the other night he was driving it stopped at a set of traffic lights but when he went to pull away there was this almighty bang

now bangs and clonks when you pull away and drive very slow

Could be a seized and broken IRD  :roll:

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

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.

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!

many thanks to all you guys for advice i,ll have the pleasure of telling him that its going to cost at lot of money at least its not me for once lol

I'd have money on a rear diff mounting. There are three and they are prone to waering out. The prop shaft bangs against the floor if this is the case. It's easy to tell "your'll be able to move the diff up and down" they arn't expensive and can be swapped on the drive with a 13 and 15mm socket and a selection of extensions. I did mine for the second time last night in about an hour. I got nime off ebay for about £15 but LR dealers are more. If it was a gearbox or IRD you wouldn't be able to drive it at all!!!

I concurr ... well worth checking the rear diff mount before jumping to conclusions.

I would say Ird unit i had the same problem started at rear diff all fine then changed viscous made it a bit better the found IRD was nacked you cand get a rebuild kit or a new one will be £750 + just for part but take front prop of between IRD and viscous and will still be drivable

On a not unrelated note, my Freelander seems to have a acquired a bit of a jerk (shut up at the back!  :roll:) when you lift off the throttle at ~70mph and then put your foot back on to maintain speed.

I was wondering if this could be a bearing that's allowing excessive play in the transmission? Any thoughts?

But thankfully it's under a LR warranty at the moment.
