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?
I could use jack stands to lift both sides of the front end but I heard that this screws up the air lift system and that lifting one wheel at a time is best to avoid this. I agree this makes no sense otherwise how would technicians be able to work on the cars in a timely manner. I read it here but I can't remember which thread.

If you disconnect the battery, the only issue that I have read about is that the sensors don't like being in an extended position for a long time. But that doesn't really make sense to me unless the sensors are old and on their way out already. And a "long time" is probably a lot longer than the time it would take to do this job.

Thanks RRS_TX, I'll do that for the install. Tonight I'm just gonna put the car in off road height, cranky the wheels to the sides and check the links for play in the bushings and go from there. Hopefully this will tell me if the bushings are shot.

I have not noticed any difference jacking up one side compared to any car.

Front end clunking solved.
Hi guys, here is my 2 cents... I bought 2009 RRS SC with 96k miles out of Alabama and while I drove it back everything was normal, only in NY (we have roads below 3rd world countries level) I felt violent slam bang over bumps. LR tech quickly pointed to significant play in sway bar bushings. After replacement there was huge improvement but still noisy.. I fugured, lets go further and had both LCMs replaced along with sway bar links and toerod ends which improved the ride/handling significantly but did not take care of clunking completely.. I had ordered pair of Airstruts from Arnott and OEM upper control arms but wound up changing airstruts only as upper control arms were absolutely fine. Now everything is nice and smooth. While airbags were OK, shocks absorbants built in to assembly had failed. Another observation regarding LCA - I think what happens is, bolt that holds LCA to the frame gets fused to metal cartridge inside the bushings and LCA can no longer pivot on it which leaves the bushings to take everythings on itself causing rubber to rip eventually. Perhaps removing that bolt, cleaning and assembly back with plenty of antiseeze compound would make LCA last for a very long time.. Sadly wheel alignment will be nesessary after that.

Roman,

Do these struts have bushings on top and bottom?
Seems to me that shocks themselves would not make noise, but where the struts are fastened could.
I have changed my bushings, and LCA's. I have checked the end links and they are tight, but like you, I still seem to hear knocking and bopping under there.
Thanks

Airstrut mounts with 3 nuts on top, I would imagine there is a some kind mount/bearing built in on the top and yes, there is a bushing on lower part/mount which did not look terrible to the naked eye. In any case, it is my understanding that when shocks absorbant does not do its job, hitting the bump or poth hole would send a suspension in to violent stress and produce noices, reduce stability/control etc. so for 100k vehichle I knew it will bring resaults and it did.

I find it absolutely HILARIOUS that almost NINE years after me creating this thread about getting the noise on my (then) brand new RRS S/C, it seems like many owners are still struggling with this issue and dealerships still seem to be totally clueless about it.

I can tell you with utmost certainty that in my case it was sway bar (a.k.a. anti-roll bar) bushings. Every time the dealer replaced them, the noise was gone for about 6 months, only to come back like clockwork. I must have forced the dealer to replace the bushings about 4 times during my 3-year lease on my '07 RRS S/C. It was always an annoyance more than anything else and never affected driveability of the otherwise awesome car.

I am now driving a '13 RRS S/C (just broke 30,000 miles). No clunking! So I guess there is at least one proven way to permanently stop the noise :)

Man, I had them replaced as well and *poof* clunking ceased. However, the clunking has returned. :(

I had the elusive front end clunk as well in the right front. Replaced sway bar end links and no change. Removed sway bar links and clunk noise was cut in half but not gone and still real annoying. Finally the right front strut bag blew. Changed entire strut and clunk was gone. Re-installed sway bar and clunk is still gone. It turns out all the noise was coming from the strut. (I had checked all suspension parts and strut bolts were tight previously)

I have the same exact clunking sound that kind of sounds like a nonstop drum being beaten while going over any bump and turning the wheel. I have brought my RRS everywhere for diagnosis and it's done no good. Bushings and every other imaginal small remedy done and still the noise.

Did the sound go away after replacing this stabilizing bar?

I have a clunking issue as well and my lower control arm bushings are bad and I'm being told to replace both arms I'm curious have you guys used non OEM arms and have they held up the same as OEM cause I see arms on eBay for like $200 costing me $400 for both but non OEM. The OEM ones are $1000 what do you guys recommend anyone used non OEM ones ?

Hi, I installed OEM front lower control arms. They were about $300 a piece from Atlantic British. They, also should be available from FCP Euro. Aftermarkets are about 200/pc. If you go aftermarket, I'd suggest buy from FCP Euro, that will come with lifetime warranty so you don't have to worry about longevity etc. At any point, you can file a warranty claim and receive the new ones. Which ever path you take - please order a hardware kit - new bolts and nuts that hold Control arms to the Body/Frame. Odds are they're terribly rusted and worned out inside and it is highly likely your mechanic would have to destroy them in order to remove old arms - this is very very important. also, make sure the mechanic will be very generous with anti-cease compound when installing new bolts.

I used the cheapest after market ones and 2 years and 30,000 kms later they are still fine. To me the welding looked better on the after market ones than the ones I removed.
I paid $425 Cdn for the pair. Then you need an alignment for which the stealer charged me $260.

The clunk is a built in feature of all RRS. Just get used to it.
