Mine did that, it was the lower control arms.

I would like to add to this hilariously long running thread...I have been trying to get this "thud" sound fixed since 2008 on my 2007 RRS S/C but to no avail. I now have 58,500 miles on her and that "vibration"/"thud" noise is getting progressively worse. I've taken it to LR Dealerships in MN, FL and now in NJ -[one indy (Rover Specialists mentioned in this forum as good) and one dealership]. Indy replaced my front strut assemblies thinking that was the problem, NOPE! Dealer replaced rear sway bar bushings saying that was the problem, NOPE! Took back to dealership yesterday. Did a ride with tech, he heard/felt it too. Then SA calls me and tells me bushings are fine and they can't find anything and that Service Mgr will drive in morning. Just got off phone and now SA, the other tech from yesterday, and manager can hear noise but "want to be sure we're all hearing the same thing" so they asked me to describe it again. I told him they've had 3 ***** experts drive the vehicle AND AGREE there is something but "we need to know what you're hearing to make sure we fix the right thing." WTF? I then told SA that if there are more than one issue going on, let's get those addressed too, shall we. I even have an extended warranty which would probably cover some or most of this issue (at least bushings would be). I don't think I'll ever own another RR again. Can't trust anybody.

Here's something you could try. I use this to find noises on my truck.
1. Buy a gopro.
2. Set it up under the car pointing at different areas.
3. ride along and make the noise then examine the video.

If it's a popping when you stab at the brakes while rolling, it could be the LCAs. Thuds from going over bumpy terrain at low speeds, maybe sway bar bushings. It's kinda hard to tell which of the ~8 possible parts it is, but the cam helps.

Not sure if you were replying to me C4attheDoor or to the thread, but thank you anyway. Now the dealer says they can't find the noise in question although they all heard it. They also came back and told me after performing a road force balance, there may be a Steering Rack issue. I have no idea why they would balance the tires when they're claiming they are all worn (but that's another thread). Based on this, I should be able to write a book in "tires" thread, "dealership experiences" thread. ha ha

I haven't read all the posts in this thread, but I get the clunking noise on the passenger front side of my 2004 RR when going over rough surfaces, braking at speed and turning right. If I go under the car I can move the passenger tie rod end (aka upper control arm) from side to side by hand. The drivers side is solid. So I am replacing the bushing. RAVE says I need to replace both sides. I have also had to replace the wheel bearing on the passenger side twice, and it looks like the bearing has gone again after only 1000 miles. I hope that fixing the bushing will stop the bearings from going.

<<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.>>

And--
<<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.>>

After changing out my LCA's a few days back I thought that the clunking sound had vanished. The temperature outside has now fallen back down to 5 to 10C from 20C, and the noise is back. , New sway bar bushings and new LCA's. Double checked the end links which are as tight as brand new.

I am getting the feeling that this is unfixable and may in fact be the Dynamic Response characteristic.

My next move is to hook up some chassis ears. Seems to only happen when there is a crack in the road where the wheel falls a bit. Also sounds like it is coming from the driver's front.
This sound is more annoying IMHO because of the fairly harsh ride one has to contend with and the fact that I expect better on an otherwise fine truck.

Further-- the LCA bushings, except for the seized rear bolts appeared fine in the arms I took out.
The new bolts, etc. seemed to help with a great alignment as far as handling on bumpy roads at speed.

Could the problem be motor mounts? Does almost sound like exhaust system bumping into something.

To put a end to this all this clanking noise is its the say bar bushing. I have a 06 rrs and my "clunking" was coming from the driver side and rear passenger side and today i just got my bushings replaces and bam the little rattling sounds are all gone and my range is all brand new again feels and sounds amazing. Bought bushings from Land Rover and had a buddy of mine to install for $100 bucks and good as new. My RRS has 72k on it by the way and they were really worn out.

Getting the same here. A dull THUD when pulling onto the low curb to enter my driveway. I have no clue but from my experience with other cars, if it's not the ball joints, which I don't think it is as I've heard that noise before, could it be the bushings?

I'd replace sway bar links (cheap) when doing bushings - those will be well worn by 70km ....

Thanks Alpaca. I looked into the price of sway bar links and you're right, at 50 bucks a pop they are pretty cheap. Also on roverparts.com there a vid that shows you how to check and see if the links need replacing but I'm wondering if there is a way to check this without raising the car.

Not OEM. I'd rather take the hit and go OEM than risk it failing. Just Think about it. There's a reason why it's that cheap.it could be the type of metal used or it could be the type of material they are using for the bushings. Either way for me, the extra money is worth the peace of mind.
If that's the case, let the dealer repair it. (Think about it) ;-)

Why? The dealer part already failed.

A month back , I changed out my lower control arms. I went for the cheapest ones on ebay. They were 1/3rd the price of the next one.

So far, no problem, and I did notice that the welding on my new arms was much nicer than on the arms that I took out.

To me I doubt that they would try to save some money putting cheaper rubber in a bushing that was already available or a ball joint that was out there by the gazillions.
BWDIK?

You guys have a point but Arby yours are 1 month old... It would be nice to hear from some people who have had these on for a year or more.

Arby, when you swapped yours out did you use a lift or did you just raise the truck one side at a time?

Actually, that site is from this thread Canrover, being most that got the parts, from this thread, which is very old, got it from that site. I understand what you're saying, but I think you may be over thinking that a bit (@least for these particular parts)

Some, I agree, you want to be sure about, but these,,,,,,, I think you're fine; again, I say, "Think about it, the OEM part is ONLY $50...

I guess you have a point. I could buy these, install them and if they fail who cares, I'm out 50 bucks cdn (shipping, taxes and all) for two of them and I can just go get the OEM ones if I really feel it's necessary. Definitely worth considering.

So how hard are these things to change when you're lifting one wheel at a time?

I have undone mine a couple of times. A bit tight for space, and you need to hold the stud part with an allen key to stop the ball from turning. So far I have had three undone at seperate times and they always feel very tight and not worn at all so I have just done them back up.

PS: In my post above I was talking about control arrms not end links.

One wheel at a time would be extra challenging. You will have the sway bar under high tension with the vehicle uneven.

What are you using to lift and support the vehicle? Can you not get a second set?

Are you sure about the high tension. Seems to me that I undid one end of the end links when checking the bushings and never noticed any special tension. IIRC, I was expecting that possibility, but it never happened.
