Rear Suspension Rattles / Bushing Replacement
#31
Don't know if it's possible, but it might be worth while to check the tightness of the bolts as well (if you havn't done so already). If the shocks themselves aren't directly the culprit, it could be that the adjustment of the suspension (stiffness) just changes the way in which the jarring responds -harsh versus mild that causes you to think that its lesser - once again, just throwing out thoughts.

Okay! We have a diagnosis, I guess it took the techs some time to find it. The local Lexus dealership sent me packing with the explanation that it was my spare tire. Thankfully the Toyota dealership put a bit more effort in. Parts and labor will be about $430, it could have been much worse! Picture of the dealership's diagnosis in the link below.

What you can do yourself (if you have time and are willing to bother) is get under the GX and ask somebody else to rock the car from side to side by pushing it and see if you can pin point the noise yourself.

There are rubber bushings on the stabilizer bars which are known to produce the clunk on the GX460 (can happen in both front and rear) which is solved by replacing the bushings. It seems like they want to replace the whole stabilizer link and I guess the bushings will be replaced at the same time. It's hard to say what exactly they did based on the descriptions but I would ask them to explain why do they think the whole link needs to be replaced. Thought it very well may be that that is how the part has to be replaced by the dealer -- many replacement parts come as larger assemblies.

Can you tell me which piece goes bad on the diagram below?

For GX470 I believe you would be looking for these but the part numbers might be different depending on the model:
48815-60200 (BUSH, STABILIZER, FRONT)
48849-60040 (BUSH, STABILIZER LINK, FRONT)
48818-60010 (BUSH, STABILIZER, REAR)
the best way is to contact your Lexus dealer and find out part numbers for the bushings based on your VIN#
GX460 all come with KDSS standard.

Well, I got the car back yesterday and the clunking still exists. The dealership called me and said that they the sound was much better (it is) but there is still a very notable clunking noise. It no longer rattles but it clunks. This makes sense to me because the sound becomes less noticeable when I switch it to sport mode from comfort.
Further investigation by the dealership showed that the shocks in the rear are cooked, and I'm sure the ones up front aren't far from cooked. So it looks like I am going to have to replace them. Mine are the adjustable ones, are there aftermarket options for this?
So much for certified pre-owned

This site may be an option for you. I had them quote a complete GX air suspension kit for a little over $2000

Lolrax, are you still having this issue? It is weird tgergen's new GX would have the same noise. Do you guys think it is possible this is just a normal noise/feeling of the KDSS working? Have you test driven a new one to see if it does the same thing? The similar noise I am having on my GX470 also isn't as bad when you put the suspension in Sport.

At any rate, I am not sure what the noise is at this point, or if it could be related to the ride height, but something is amiss.
edit: The noise only happens when taking a hard left turn over pavement with a bump (when making the suspension work hard)....putting a good amount of stress on the RR. Maybe because the RR is lower than the LR it is putting a high load on the RR causing the noise, I dunno.
