Default STi question - knocking sound from steering wheel when going over bumps

I've searched and couldn't find anything.

I've had my '04 STi for 6 weeks, 1500 miles, totally stock.

I've noticed a noise lately as I drive the car harder (out of break-in period ).

Here's a scenario: making a turn, maybe a freeway onramp or a turn at a light or something, doing a pretty decent speed, accelerating and the surface isnt perfectly smooth (nothing too rough).

Each time I hit a small bump and/or a front wheel loses a little traction or hops, I get a pretty distinct knocking sound somewhere in the steering column. Its a metal on metal type sound.

Anyone else with an STi heard this before?

Thanks,

-Mark

Even if you have to drive a hundred miles to go to a 'good' dealer near you it is worth it.....look in the Deler reviews forum and see if one is better or, maybe more important, worse than others around you......and ask in your local area forum for who to go to or who to avoid in your area.

From what I've read and experienced, the steering rack bushings are crap for the WRX and they are the same crap for the STi and loading the steering by driving the car hard and by increasing the cornering capability of the vehicle brings out the crappieness even further.
I don't know if there is a mechanical fault that may be causing these issues, but it bears inspection at least and

I would get and install the Whiteline steering rack bushings in a quick heartbeat....anyway.

I think this is "normal" on these cars. Mine does the same thing... as does another friend of mine's. Pretty annoying.

Imprezas do this. I have found a bunch of threads about this. Wrx's, RS's, TS's. Sti's too, I guess. No one has ever come up with a satisfactory explaination. People have gone to dealerships and gotten the "it's supposed to sound like that". I don't think it is the steering rack bushings, I think it is in the suspesion somewhere. Kinda sucks.

Mine is driving me nuts. I know the car is a good deal - but why does my brand new STI sound like my 1970 Karmann Ghia over bumps? New steering rack bushings did NOT fix this. Nor did the stupid dealer.

So, I'm not the only one with this issue...

Its very much related to wheel hop. I can't actually tell if its a strut top, rack bushing, CV joint, or something maybe to do with the actual steering column. The sound is very close to me when it happens. It just sounds like the steering wheel or column is knocking.

I have my doubts that there is actually anything wrong with the car, but its annoying. My WRX wagon never made this noise (prodrive springs with tein camber plates).

Please post if you have been able to isolate this noise or find a solution.

Thanks for all the replies,

-Mark

When I bought the car the first thing I did was set the steering column "tilt" as low as it would go.

After that I noticed that I had a clunking noise in my steering column while going over moderate bumps. I was able to alleviate the problem by raising the steering column up slightly from the lowest possible setting.

I do have a new clunking noise but I think that is either strut tops or steering rack.

Hope this helps.

i hear clunking noises also (knocking), when turning into my parking garage, steep incline, sharp turn. the rear wheel hops off the ground a little and the car makes a "clunking" noise. the noise (in my case) is most definately one of the differentials complaining. it's the same noise the car makes when the dccd is set to open making a sharp slow turn.

maybe you're hearing the same thing? if this is true the noise sounds close to you because it is, it's the DIF trying to quickly redistribute the torque to the 3 wheels that are still on the ground and it's binding a little.

That's a great observation Doug. I've heard that before too, but the noise I'm describing is definitely not coming from the driveline, its coming from the suspension.

The more I become comfortable with the car (post-breakin period), the more I've started pushing the car and driving in a more spirited fashion . Consequently, I'm hearing it more and more now... Its coming from the front and it gets transferred through the steering column. I don't think its related to the steering column or rack, but the knocking gets transmitted up to the steering wheel, if that makes any sense.

I have the same issue with my 04 sti. I think it may be coming from the drivers air bag shaking in its mounts over bumps. To rule this out as a cause i am going to drive it without the air bag installed. If it fixes the issue i will let you guys know. Not sure what i can do to secure the air bag if this is the problem, but atleast i know what area to look into further.
