Default 2015+ WRX Steering Rack Clunk

It seems that several users have report having a clunk coming from the front end when they are either driving slow (less then 5mph) or stopped, and move their steering wheel back and fourth quickly.

Here is a video of me reproducing this noise for reference:

It seems to be a problem with the electronic steering rack itself. There are other common sources of clunking in the front end, that further complicates the matter. Sources of these other clunks are commonly from bad Strut Top Hats and Strut related issues.

It seems that this noise isn't apparent when brand new, but occurs within a few thousand miles after use. For some users it gets worse after time, others it stays the same. A few members have had their steering racks replaced by warranty, which initially solved the clunk, but it returned shortly after.

I have had this issue since about 2k miles, and I am now at 16k miles. The noise hasn't gotten any worse.

I am creating this poll to see how common this issue is. Please only answer in regards to the clunk in the steering rack, which is reproduced when stopped, and turning the steering wheel back and fourth quickly, like in the video above. I don't want to skew the results with the other common front end clunks our cars have.

In addition to the poll, please reply with any information you can on your own experience with this issue. What have you tried to fix it? Have you had any success? How long has it been going one? Has it gotten any worse?

Also, the following thread has more details on this issue:

I've noticed the stationary clunk get progressively worse from ~20k miles to 40k miles.

During this time I've had RCE yellows with stock struts, and now I currently have BC coilovers. 2017 base model WRX.

Tried to listen for this this morning, I don't really hear it like in the video. I do have marshmallow spec winter tires on at the moment though.

Tangentially related, on other Subarus people change out the rack bushings, but that's not something anyone does on the EPAS models. Has anyone ever looked at the bushings on these?

In all likelihood this would make this phenomenon more noticeable not less, but I'm still curious

I feel like mine has always done this. I am at 18k miles now... Perhaps it is just a characteristic of the racks used.

Id like to hear if anyone's rack has actually failed or developed play.

they are very soft. you can see them and squish them easily under the car. i asked Perrin if they are planning on making firmer ones and they said not right now.

STI rack is hydraulic, WRX rack is electric. It is not an easy swap, you'd need to add a power steering pump.

I am glad this thread is getting more responses, I figured it was dead. It is good info to have!

Killadawg, are you saying you are going to replace your Electric Steering Rack with a hydraulic one from a STI?

2017 wrx premium model here, it's the wife's car, but I noticed the steering clunk shortly after purchase, had less then 1K mile when I noticed it. Have not spent any time trouble shooting, most likely will just take it back to dealer since it is under warranty period.

I have a 2017 WRX that does the exact same thing. It clunks when I turn the wheel at low speeds and also if I move the wheel back and forth when I am parked. I brought the car to the dealership and they said it is "characteristic".

Yup I know STI and WRX have different type of steering racks (I also have the full set of STI parts (W\O the engine and interior.. half which is already swapped out ;-) yet not sure I want to wrench with this.. all working fine, and I can live with a small clunk at low speeds. I know mooresport makes a subframe for the VA chassis that might eliminate the clunk and if I do go the hydraulic way I will add that subframe as well. This summer I'm switching to MCS 2 or 3 way suspension, so I shall see if it is the top hats that does this noise, as with that setup stock will be replaced.

BTW for me the Dealer has been just trouble, every recall they forget to plug something in, or my hose clamps are on loose and blow out on they way home with no tools..etc.. good luck with that.

Default Definitely have this.

I copied my response on another, similar thread, here it is:

I have a 2015 WRX, bare bones model. I bought it around January 10th of 2015, give or take a few days. It has, to my knowledge, had the clunking since I bought it, though I didn't notice it being very pronounced until it reached the 10,000 mile area.

I just took it to get it looked at a week and a half ago, from the time of this forum post. They apparently *were* able to duplicate the issue, and referred to a particular TSB about the front strut mounts (Subaru supposedly altered the manufacturing process specifically in terms of the front struts, which must have lessened this issue? I have no idea).

Nevertheless, they apparently ordered a "kit" (service rep's own words), and fixed it, along with a free alignment. And the sound is still there, and seems even worse and more "harsh" now. It's really aggravating.

Since I'm a new member, I can't vote in your poll. I *do* have the clunking noise, and I *did* take it in for service, however, the steering rack has not been replaced.

Same issue here comes from the front right at low speeds, haven't bothered to trouble shoot at all. 40k BC coils, whiteline sways and links

I have a 2017 WRX with 40k miles. The noise has gotten worse over time. It's really loud under 10 MPH. Whats the fix to get rid of this noise? If not replaced, will it cause any damage?

Did that fix the issue and now there is no clunk?

I came across this post on another forum that lists the wrx as well but there is a dealer procedure to adjust the steering rack and replace a spring that is supposed to relieve some noise. If it doesn't then a new rack replacement is warranted. I took mine to the dealer for the noise and they told me it's normal and turned me away. Im considering trying this adjustment myself instead of wasting another day at the dealer. The spring it about $15 and the lash adjustment is free but in the diagram is looks like there is a speciality tool needed. Not sure if u can do the procedure without it but it looks like you have to remove the rack from the car to get to it. See the post below and there is an attachment on one of the posts that shows the lash adjustment
