Clunking noise from NSR

Got a 57 plate L322 TDV8 with 70k on the click.

Hello I have an issue regarding a rumble for the NSR on my Vogue TDV8 (2006). I noticed that on an intermittent basis, when maneuvering on a left or right turn, that a rumble appears to come from the NSR.

I have managed to get the fault to occur on super smooth roads and at speeds from 1mph upwards. The new thing I have noticed is that if the rumble occurs, I can stop it by simply bring the vehicle to a halt, turning off the engine and as soon as i turn the ignition to position one, there is a "release" (the back end loosens / lifts up as if a brake has come off but I dont put the electronic hand brake on excepy when parkin up) and the rumble stops. The LR dealer witnessed the fault and said something about a "solenoid" acting on the NSR diff / drive shaft could be at fault, but is its intermittent, would you have an opinion or explanation of what they could mean before I book it in for investigation. Any thoughts would be greatly appreciated. Thanks. Paul

sounds like the handbrake shoes may be sticking, or breaking up and catching every now and again, had same problem with a bmw 760 recently. where abouts are you?

Based in Leeds.

Thanks for the information.

Holy necropost batman!! What happened to the year inbetween?

UPDATE.....Finally got to the bottom of the problem (NSR juddering on cornering). It seems the problem is with the Haldex motor (electronic torque management system) on the rear diff. Apparently this motor thru a clutch type assembly is used to lock the diff up, or stem power flow to one of both rear wheels. In my case it keeps locking up the rear diff for no apparent reason, so when cornering the wheel on the outside of the curve is being dragged along....LR dealer repairing as we speak.
