A noise has developed over the past few days. When reversing into a parking space or onto my drive after probably one revolution of the wheels there's a clunk from mid-rear underside. At first it felt like something falling over in the boot space. But today it sounded more of a metallic 'clunk'. it's almost as if one wheel is slipping momentarily.

It's a 2.2 TD4e Manual by the way.

A ring from the prop shaft maybe? have you got a worn UJ?

Hi Landi

Had a look underneath this evening as things have progressed shall we say?

As previously reported the clunk seemed to only happen when reversing. This evening on my way home from work I joined a roundabout from a standing start and the clunk came in in first and second and there was a repetitive thump thereon.

I jacked up one wheel on the rear. Turning one of the rear wheels (other three on the ground) the clunk was quite audible. There is no play in the driveshaft, or any of the UJs but if I went to the front of the main propshaft and waddled it there is what appears to be almost a slip in the input to the Haldex

Is this a symptom of Haldex failure? Will it fail/let me down? How much.....? 2010MY 2.2 e4 (gone but, not forgotten)

Hmmm dont really know about that, but its obviously not right and I would take it straight to the dealers for their opinion as if its a bearing or gear going it might damage things beyond all repair and you end up needing a complete new diff etc, and that would be more expensive than just a bearing say.
Must be an internal thing is you say you cant see anything obvious like a loose bolt/fixing and I suppose it could lock up?
If youre under warranty they should do it for nothing whatever, but if youre paying its different.
I wouldnt drive it anymore than you have to, or even ask LR assist or if youre a member of the AA say come out and advise??

Hi Landi

My warranty ran out about 3 weeks ago would you believe (it wasn't a LR one).

My dad and I had look underneath and there is no play anywhere, but the input to the Haldex seemed to be the culprit. I am not confident of driving it to be honest.

I could do with finding a good indy local to me (i'm in between Wigan and Liverpool) to have a look.

The b@gger of it is that we are due to be going on holiday next week and looking forward to the trip in it. Some things are sent to try us I suppose? 2010MY 2.2 e4 (gone but, not forgotten)

Thats just about as unlucky as you can get, just out of warranty, almost as if they know isnt it??
If your cars mileage is low maybe you could ask LR for advice whether they might do a good will gesture, they may pay part of the cost, I suppose it depends if its always been service by LR agents though, they may say no if others have had a dabble?
In some cases they do help out, cant do any harm asking??

Just a thought but have you tried it in one of the off road modes selected and see if it still clunks? doing that will engage the haldex??

I will have a go in a TR mode. It looks as though others are experiencing a jolt from the Haldex on another thread. I may be worrying about nothing.

I could do with finding a good indy local though. 2010MY 2.2 e4 (gone but, not forgotten)

Maybe, mine doesnt knock or jolt though so they arent all like it and as you say youve only just noticed it? just as the warranty ended unfortunately, if it was normal surely you would have noticed from the word go and questioned it then??

Unless youre now doing or have done something different with car recently, like going off road or towing maybe??

I had another look/go with it this evening. The clunk is there as a repetitive noise now in forward motion most noticeable when turning left. It's a bit like a cv joint type noise. If that's the case then it's an easy fix. The thing is I'm not getting any fault lights or messages. A bit of a puzzler 2010MY 2.2 e4 (gone but, not forgotten)

If it was a wheel bearing or drive shaft joint you wouldnt get any warning messages, I dont think the system is that clever it can detect all faults that may occur wherever?
Although when my diff pinion bearing went on my 2010 I never got any warning messages for that either, it just got noisier and noisier over a period of 200 miles or so, so it happened quite quickly.
That was £800 to fix at the time and they had the car 2 days.

Yes, the 'brain' can only react to the info sensors can give it. So something mechanical such as pinion wear or UJ's won't flag up. That's why I'm thinking its not necessarily the Haldex. There's a worm in my brain suggesting CV joint - needs more checking.

By the way I did try it in the TR programs last night, no difference. 2010MY 2.2 e4 (gone but, not forgotten)

Took some video this afternoon. With rear wheel off the ground we span it. there is a hell of a noise. Only the odd clunk heard in the cabin though. A vid showing (not clearly) the play in the main prop going into the Haldex, is this within limits? Also a vid of the play of the union going into the diff, its the same both sides. I am applying up and down force and the movement is alarming. Is this within limits? No such play on the fronts by the way.

I hope the link works!

Just a curiosity have you checked the haldex oil level❓
I had a clunk and a sort of grinding noise whilst pulling a way at junctions when turning this was caused by a very low oil level it caused the haldex to not disengage whilst turning.
My fault was diagnosed by my local indecent Landover specialist.

I haven't checked the level in the Haldex. Good time to I think? 2010MY 2.2 e4 (gone but, not forgotten)
