I have searched all the Land Rover forums for help and have come to the conclusion that we are extremely fortunate to have LCB. They are rubbish!

My everyday workhorse Discovery 2 TD5 developed an alarming banging and grinding noise when making right hand turns over about 25 mph. It feels as if it is coming from the rear near side.

When running straight and on left hand turns it runs a sweet as ever. My first thoughts were a wheel bearing breaking up, but I would have thought it would make some rumbling noises at all speeds and cornering loads? I have tested the wheels for any slack but all seems fine.

Any ideas before I start stripping the back end down?

This may sound stupid BUT - are the wheel studs tight?

I had a p38 range rover did that, wheel bearing gone but you will not feel it easily even jacked up as the shaft is supported by the diff.

It was a PITA to remove the bearing.... needed a 100 ton press

bust the bearing and get the welder on it will come out with ver little pressure just had to do it on a focus, wouldnt budge a mm with pressing it or smacking it with a BFH applied the arc weldet to it a couple of taps and it dropped out

Yep, sounds like wheel bearing to me.
I'd change it now before the inner race/s weld themselves to the stub axle.

Wheel bearing definitely.

Note: the rocking the wheel check is to detect a failing wheel bearing in case it doesn't show any symptoms whilst driving, it doesn't mean that if your car is making apocalyptic noises that your wheel will wobble when you jack it up.

Replace ASAP before it ruins the axle/hub

And yes, this forum is far superior

Another for wheel bearing here.Mine just collapsed and momentarily locked up with no warning,(fair do's the nobblies made quite a racket) which may have drowned it out.

Thanks for all your input - I have now discovered the problem and its nothing to do with the wheel bearing!

I stripped down the back axle and remove the hub assemblies. It was soon obvious that there was little or nothing wrong with them. At £200 per corner (on Disco2's the hub/bearing carrier is a sealed assembly) I wasn't going to buy new just to find out if that was the problem. So I put it all back together and checked out everything else in the suspension/drivetrain. Eventually after eliminating everything else I had a flash of inspiration and disabled the active suspension ECU.... Voila problem solved!

So now it drives just like a Disco1, i.e. a bit wandery and rolly, and I have a nice little light on the dash saying the ACE system isn't working. I'll sort it out one day, hopefully just a dodgy sensor.
