Default Excessive Tire Noise

car: 2005 Sti- completely stock

ever since i got my car back from service my tires screech and chirp during normal driving at normal speeds. turning is ridiculous and i dont understand why it keeps happening. even when going straight if there is uneven road the tires can chirp while going over it. the dealer supposedly replaced a part in my rack & pinion that was leaking (or replaced the whole thing, im not sure) but besides that i have no other leads. i am planning to take it back to the dealer, but i dont have a specific part to blame. could it be my differential?

thanks to anyone who can help

It could be your alignment. How are your tyres wearing? If they changed out the rack, or disassembled it for the component replacement, they would have to set the toe.

Don't settle for a "Green" alignment. You want. 0*00" toe.

School me. What's a green alignment? Will 0 toe reduce tire wear? RP

Zero toe will help with tyre wear.

Like any specification there is a tolerance range. On an alignment rack the tech can move things around until the needle is in the green. (Now it's a GUI, but you get the idea.) For the street Dead Nuts 0 toe is a good compromise. It is also in the middle of the spec.

For camber, even if you only take freeway ramps hard you want max negative camber up front. If you can get into the red negative, out of spec, so much the better.

No question that the dealer screwed the pooch. The question is where? An alignment check is an easy place to start.

Yes, a locked differential will make the tyres protest. The tyres chirp and the car will shudder as they fight each other. I'm just not sure how they buggered up a diff, or diffs.

Way back I had a welded rear end and know exactly what those symptoms are. Massive understeer too.

OP: Have you played with the DCCD switch and dial?

Edit: Just remembered the Steering Angle Sensor. If they R&R the rack and didn't get this right it could be confusing the heck out of the DCCD:

Could they have miss stabbed the rack and rather than do it right just re centered the wheel on the shaft? The DCCD would think you are in a constant corner going straight...

web foot, thank you very much for you input and im going to use your ideas when i get mad at the dealer for WTF they did to my car and how fast they are going to fix it lol

i have never changed my DCCD(ive left it on auto since i got the car) settings but i would agree that that is probably the best lead. i really think whoever was working on it at the dealer probably did what you said and adjusted the rack in a way that was ignorant of the dccd

Might want to put the DCCD in manual and try full forwards and full back on the dial and see if that changes the feel of things.

Another way to disable the DCCD is to pull up on the parking brake. Do not engage the brake shoes, but leave it up just short of that point and drive around the block and see if things are better.

Good luck.
