Hi All,

So after a few days of driving around I am noticing a clunking sound coming from the left hand side of the car when I go over a speed bump or pothole. Seems to be coming from both the front and rear left hand side. The air suspension is working fine and there doesn't seem to have been any loss in ride comfort etc.

Any thoughts what it could be?

Thanks African Bush Junkie ... in London!

Had same on mine, but seemed to be only nearside front wheel.

Dealer I bought the car from sorted it.

Changed both front drop links - not fixed.

Changed complete front anti-roll bar (with bushes) - not fixed.

Changed passenger side front lower ball joint - fixed.

Good as new now.

Obviously yours may be different, but I had exactly the same noise.........

Awesome. Thanks Scarey.

I need to practice more on the search function methings ... will get the drop links checked out by the guys who sold me the car. African Bush Junkie ... in London!

Good luck sorting the knock out, had mine for months & spent a fortune. It's still knocking

replaced
front arb drop-links
front strut
ball joints
rear top & bottom bushes
control arms front & rear Range Rover 4.4 V8 Vogue

Mine was the near-side track-rod end. Very definite clunk, and now gone. £70'ish for the LR part and £40 labour at my local independant.

I presume these are the Drop Links and therefore First port of call to change. (highlighted yellow)

Ditto

Yes, they are the drop links........

The dealer said that they seem to have an issue with the Supercharged where they have to replace the drop links and anti roll bars alot, so that was their first port of call. Not sure of their thinking, as mine is a Td6....

You can't get anti roll br bushes without a new anti roll bar. That was about £100 if I remember right, plus fitting.

As I said, turned out to be the lower ball joint. They had to get the welding gear out to free the old one.........

My car clunks all the time, changed everything bar struts.

I've had cars fail MOT's for worn suspension joints that have shown no sign of being worn, i.e. no clunking.
Yet here I have a car that clunks, and the joints pass MOT's!

I suppose it's to much to ask for a quick fix, but something is behind several vehicles having the same fault.

ARB bushes, bottom balljoints, castor arms, track rod ends can all cause noises in the suspension

Just found this on another forum, looks like a DSC issue..

Does this mean we just have to live with this?

Dynamic Response / Ride and Handling Optimization System Noise

AFFECTED VEHICLE RANGE:
Range Rover Sport (LS) All vehicles equipped with Dynamic Response system

CONDITION SUMMARY:
'THUD' FELT OR 'PULSE'/'CLICKING' NOISE HEARD FROM UNDER THE VEHICLE
Situation: A customer may report a concern of an under-car 'thud' from the front or rear suspension, or an under-car 'pulse'/'clicking' noise from the dynamic response valve block or hydraulic tubing. In some cases, the noise may be described as similar to 'water hammer', the noise experienced in a domestic water system when a faucet is turned off quickly.

NOTE: Changing any of the dynamic response system components will not eliminate the noise. Visual inspection for problems and torque checks must be completed.
The described noise is a characteristic of the dynamic response system and is generated when there is a sudden change in oil flow in the hydraulic circuit. This is a result of a direction control valve switching in response to driving inputs. The change in flow will be accompanied by a pressure pulse, which will be transmitted through the hydraulic and mechanical
components associated with the system. The duration and amplitude of the pulse make it audible.
There are components in the Dynamic Response and associated systems that can influence the level of the noise.
Action: Should a customer express concern regarding the above, refer to the Repair Procedure detailed in this bulletin to check the associated systems.

PARTS:
No parts are required for this bulletin. Information purposes only.

WARRANTY:
No warranty provided for this bulletin. Information purposes only.

REPAIR PROCEDURE
CHECKING FOR PROBLEMS CAUSING DYNAMIC RESPONSE SYSTEM NOISE
NOTE: The noise will not be eliminated by replacing Dynamic Response system components. The visual inspection and torque checks detailed below must be completed.
NOTE: It may not be possible to achieve the same noise level on all vehicles. The amplitude of the noise will vary from vehicle to vehicle due to natural variability, ambient and system temperature, component tolerances and dynamic response system hydraulic characteristics.
NOTE: Following inspections below, if no problems are found, it is likely that there is no fault with the system and the noise generated is simply the characteristic of the system. The customer may be informed of the noise characteristics generated by a hydraulic system pressure pulse.
1. Ensure that all Dynamic Response system connections are secure and problem free.
2. Check other vehicle components for any of the following conditions that could exaggerate the noise:
• Steering linkage integrity and securing torque.
• Stabilizer bar linkage integrity and securing torque.
• Stabilizer bar linkage damage or contact to other components.
• Stabilizer bar bushing and bushing clamp integrity and securing torque.
3. Check the Dynamic Response system components for any of the following conditions:
• Pipe work damage or potential contact with the body or chassis.
• Pipe work mounting clamp integrity and isolation.
• Hydraulic valve block damage or potential contact with the chassis.

Someone somewhere is making a fortune from L322 owners stripping out parts that are not worn...

Mine started the day I changed the front passenger strut for a Dunlop one! Range Rover 4.4 V8 Vogue

Its interesting that everyone seems to have had the sound from the nearside only ... Overweight passengers clearly  African Bush Junkie ... in London!

So ... an update.

Garage can't seem to work out what's causing the sound or rather, identifying the rogue part. All the usual culprits been tried and tested ... hmm ... African Bush Junkie ... in London!
