same thing on my 2010, started leaking around 40k miles and apparently its a very common issue with RX family. My are leaking very little so i have yet to replace them, no discomfort or anything during the ride, whether its a bumpy road or high speed maneuvering through traffic.

Thanks Yurka. I've merged the threads.

pasica, sorry to hear you're having this problem. Are you still under warranty?

 

Lexus doesn't build them per se. They get parts from OEM suppliers built to their specifications.
They do put certain conditions in their contract, such as x number of failures per set number of units.
So, if their supplier does not deliver, they will switch to the one that will. In order to stay competitive, they also put a cost reduction in place with each iteration. That may end up being counter-productive.
Considering this is a $35 part, this might explain it.

Good news, these are actual shocks, not struts, so no messing with spring compressors and strut disassembly.

The condition itself is not critical and can be taken care of at any time. The car will simply ride bouncier in the back.

I did notice there being 2 sets of part numbers. So, the newer version might have resolved this problem.

Looks like KYB has a set of shocks available:

However, they may be the OEM suppler to begin with. And I believe Toyota does requests their suppliers to provide non-EOM shocks with 10% more stiffness.

 

Monroe also makes replacement shocks and struts for the RX under their OE Spectrum line. I think Monroe and KYB may be the only 2 brand name suppliers. I do think KYB is the OEM supplier. I did see some no name really cheap replacement shocks & struts on eBay, but would not put them on my car.

The Monroe struts look like they may be a good alternative if they last as they have had good reviews on some BMW forums. http://www.monroe.com/en-US/products/OESpectrum/Struts

My rear passenger shock needed to be replaced at the 83k km (51,000 miles) mark (warranty ended at 80k and dealer didn't do anything, even though it was that close!)

 

 

That photo does not look like the rear shock for an RX350. Maybe if it was the European model with air suspension. What make-model vehicle did you buy?

Here is a link of a typical rear shock that is leaking. https://www.clublexus.com/forums/rx-...ement-diy.html scroll down for the rear shocks pics


I would get professional help, if you just bought it, take it back and make them fix it as they obviously sold it to you defective and should have caught and fixed it before sale. Replace both rear shocks.

You can clean your driveway up with any of the many oil removing driveway cleaner chemicals available at any auto parts store.

 

I had mine replaced with KYB.

They cost more than the Lexus shocks and my guess is that they are stiffer than the original.

I can't really say that with facts to back it up though.

If I could do it again I would just get the Lexus brand shocks.

 

Other folks have had the opinion that the KYB shocks had a better ride than OEM.

I note that DB11 never responded to say what vehicle that photo is from.

 

What i was told is that this is common faulty thing with RX and i had it done on my previous RX even without the warranty it was replaced at the dealer for free since it is something that is wrong on Lexus' end
