Same here. It started off only making noises over uneven terrain but now even under braking, its slight audible. I think changing any suspension component only either dampens it or aggravates it. I had my tire rods changed by some garage just after owning it, it kind of made it a little worse.


Keep us posted on your progress. Here in UAE, the dealer has indirectly admitted to the problem and its a potential hazard as one can lose power steering (as per them). The only solution they are currently providing is to replace the EPS (~$1,500).

Electric Power Steering (EPS) noisy

There's no chance of you losing power steering because of this noise. Dealer service counter people usually don't know very much.

The system is functioning as intended. Large input forces from the road are normally transferred to the steering wheel. The EPS soaks up those inputs. A side effect is the rattling. Ideally when the EPS is tight with very little gear slop, it's inaudible. On some cars, mine included, it's quite loud. There's probably a way to fix it other than to replace the EPS or straight up delete it. Either way, it's an annoyance, not a safety issue.

While we wait for a fix, I recorded a few videos of my rattling EPS and just curious to know if you guys are experiencing the same rattling or less or worse:

(you can here it from 3 secs onwards)

I see one guy simply tightened the bolts on the linkage. Some shimmed up the bearing. Mine seems to be coming from inside the EPS motor though. I've seen people take the EPS housing off and pump it full of grease. I'm really shocked there isn't more talk about this problem on this forum, especially from people who track their cars. I suspect because there have only been a dozen Twins sold and they are all low mileage compared to the gazillion Corollas that are on the road with 200K+ on them.

Tonight if I get a chance I am going to loosen and retighten the bolts on the linkage and see if that helps. If not I may take the whole thing apart this weekend and see if I can figure something out. Mine is getting worse by the day. If I do any hard braking it makes all kinds of racket.
But this steering is very different from a Corolla or Lexus. Not sure any fixes just transfer over and are meaningless although the basic ideas may work.
There hasn't been much talk because it is very rare so isn't much of a problem.

What is different about it? The assist motor looks identical. It's the gear lash that makes the noise.

Here is some video of the system on the Corolla. As you can see it looks identical. The C200h is also the same setup.

I suspect it's more common it's just people create threads like, "Clunk in suspension" because that is what it sounds like. There is a lot more talk about it on the Corolla because they sell way more and people can get more than 80K on those before they blow up. Hahaha

If you mean that both are an electric motor and a set of gears then yes they are similar but so are just about every other make. If there is a problem with the EPS on some other make it does not automatically cross all makes. Search Subaru EPS issues to find out more accurate info.

No I am not saying that because they both have gears and a motor that they must be the same. They have the exact same motor and gears. Like identical. Look for yourself rather than make assumptions. Looks like Subaru uses Hitachi with the acception of the BRZ which uses JTEKT which is what Toyota uses in all their cars. Yes I know JTEKT has several units but the unit in the 2009 Corolla XRS and Lexus CT200h looks identical. You did a lightning response to my post so clearly you didn't bother looking at that video.

Let's not derail another thread with arguments about how rare shit is. People in this thread all have the same problem and we should keep it productive.

Looks the same and are the same are not the same.
I was attempting to assist by pointing out that they are not the same but if you see everything as an attack then that is fine.

I asked you how they are different and you didn't answer. The fact is you have no clue what is inside. They have identical housings but yes the internals could be different. But you saying to research Subaru issues really discredits your argument as they aren't even made by the same company. I don't see this as an attack, I see it as you derailing another thread. Bring constructive info only.
