REAR DIFF KNOCK

Hi hope someone can point me in the right direction, noticed a clunk when setting off in my discovery 2 td5 today, got a friend to rock the car forwards & backwards whilst I was underneath it sounds and looks as if it's coming exactly from where the drive shaft meets the rear diff?? Also whilst the clunk is occurring I can feel the noise in the rear axle itself if that makes sense.. does anybody know how I can diagnose the exact problem? Thanks

A LR garage, not a main stealer, told me this was a recall item, cos mine suffers with it slightly, so this may be what your's has and maybe previous owners never took it in for sorting out. LR, from their database, should be able to tell you if this has been done or not and if not they should do the fix for free.
Best of luck.

Should have made clear, the fault was in the diff. If your clunk is at the pinion it could be a loose nut on the pinion and that would not, I think, be down to LR.
Have had this issue with a D1, do not know how likely it is with a D2. Depends on how similar the diffs, connections to props etc are between D1 and D2. From a quick look underneath I think they are quite similar, but similarity disappears on the front axle, or at least quite a bit of it.

No it's worth a try I will give them a ring tomorrow thanks for the info.

I believe there is a rubber donut between the prop and diff. These can split.

Can replace on a D1, 300 TDi with donut, for 200 TDi type without donut ... no sure about the D2 though ...

Thanks for the replys, yes I think it's the rubber donut after a quick look under there today looks like its split. I've rang LR this morning after stanleysteamer & an online search said it had been recalled for problem with the rear prop shaft on my model but she said that mine hasn't been recalled . I've bought a rubber donut kit with the bush, apart from getting the original bush out is it a simple enough job to do? Thanks

I have'nt done a D2 and haven't looked at it on Rave either, but if it is simialr then replaceing the rubber donut is the easy bit getting the bush out is pretty damn hard and you really need to get the prop off and put it in a vice and start work. The first time I just replaced the donut, the second time I replaced both. If you are pushed for time or workspace, or knowhow, I'd just replace the donut and that will get you going smoothly again and give you breathing space.

As regards the recall, is LR telling you yours wasn't part of the recall, i.e. didn't need the repair? Or that it was but somehow didn't get recalled?

Okay thanks for the info I will have a look when i recieve the kit. Yes spoke with someone on the phone from local LR give them the details of the vehicle and they said there was no recall for prop for my vehicle. But a similar search online said that there was a propeller fault causing props detaching etc for my model...so a duno I just have to see how I get on with donut not expensive so will be a cheap fix if all goes well..

OK. The recall I was talking about wasn't for props it was for a fault in the DIFF, but tbh the woman should have looked up all the possible recalls for your truck and then checked to see if they had all been done. They are supposed to have this on their database.

Sticking my neck out a bit here as have done no proper research but I think the recall may have been for the front props are they are well weird, nothing like as standard as the rear prop.

After an accident in France my rear axle was replaced with a secondhand unit over there and when I took it to a LR specialist, not a main dealer, for an unrelated fault, the chap told me that the slight clunk I get sometimes on take off is down to this fault that should have been corrected with a recall, but that it wasn't anything to worry about, at least not for the moment. If I had nothing better to do I would contact LR but I'd be screwed if the previous owner(s) to me had taken the Disco in for its recall already. Cos then he'd say, "but you've already had that fixed" and telling him the axle was replaced would probably give them the get out to say no, after all it is work for them that they don't get any money for.
