'07 i6 version. When I am driving around I get what I can only describe as a droning coming form the rear, it seems to be worst around 50-60kph and increases in volume/resonance etc as I accelerate and back off a bit as i decelerate. When I go the vehicle my LR garage told me the rear diff needed doing so they did that so I am guessing that rules that out unless they made a real cock up of it. I have some big horrible 20" tyres on it that I am waiting to get rid of when I can afford and put on some nice more discreet 17 ers, last service the garage swapped the front to the rear as the front had a bit of shudder and he said one of them had a slight flat pot on - can't honestly recall if this noise happened before the tyre swap or not.

Have tried to take a recording as I was driving along holding my phone over my shoulder not sure if it is of use. IS there a way of uploading this or is it easier to add to youtube then post a link to that?

Any ideas/thoughts/suggestions? I have come up with swapping the tyres around again and see if that makes a difference,

thanks

Judging from your comments about the shuddering from the front tyres before you swapped them to the rear I would say that is your first thing to rule out. Cheers,

I recently thought my rear diff was starting to drone, but new tyres sorted it, so I would suggest you rule that out before doing anything more drastic/expensive. Fingers crossed! 2005 D3 2.7 Auto

Good point (even though 4 new rims and tyres aint that cheap either) cheers

Yes, in my case I was simply getting new tyres a month or so ahead of absolute need, your situation sounds a lot more expensive! But if it is expenditure that you were going to do anyway, rather than a whole lot of extra work that might not be needed, then it might be worth bringing that expenditure forward if at all possible. 2005 D3 2.7 Auto

they've got a fair bit left, they are R20's (cant recall the other bits)

In my experience low profile tyres are always going to be noisier that standard, however if they have at least 5mm of tread on them I'd be surprised if that was where your noise is coming from. Mine is currently making the dreaded diff drone, which rises & falls as speed increases & decreases. I have confirmed the diff pinion bearing has failed by using a set of chassis ears, as per this video shows. If you can find a workshop with these, it can save a lot of time & speculation over different noises.

Hi Badger, is this different to a rear diff rebuild? That is what my garage did about 9 months ago (screen shot of the service invoice)

To be honest I certainly wouldn't expect a recon diff to fail within such a short period, even with the known weak pinion bearing (unless of course the rebuilder fitted cheap chinese bearings)!

I would be taking it back to the garage that fitted the recon diff & tell them that you're concerned about the noise & see what they have to say.

Good stuff, that was my thought also, they're recognized as a LR specialist over here so you would expect a decent job

With the diff having ‘known issues ‘ has anyone replaced with one from another vehicle say Range Rover evokeee

It’s the same diff in the evoque up to 2015! (Now Sold). 2008 Freelander 2 (Nazca Sand) SE TD4 Auto. Statutory write off & on WOVR for hail damage but still road legal.
