i have a 05 sti with 15k miles on it and i notice a shudder type feeling on slow left hand turns has any one experienced this and should i be concerned?

[wacerx]

mine does it and i have an 07 with almost 15k. i have wondered the same thing but it seems alot of people experience it. i would also like to know if steering bushings can solve this problem since it is quite annoying at time.

Checked your brakes lately?

Midas?

Check this out first: is your DCCD set to auto, or was it put in full lock? Full lock will cause the car to turn poorly at low speeds.

i have the dccd set to auto and my brakes look fine it feels more like maybe a tire skidding across pavement front end is tight and the alignment is in spec i set it myself but not sure where it is comming from

Chances are it's the differentials grabbing. Shouldn't happen ALL the time, you might want to have the diff fluid checked to see if it's burnt (sometimes causes binding). Lastly, if you notice this at autox, then yes this is completely normal. If it's happening continuously on the street, I would have it checked.

have you had your diff fluid changed?

did they use the jdm spec 90wt?

my '05 has never had the diff binding/clunk issue. i have always made sure to use the subaru 90wt. it seems no other fluid is gl-5 and has the right additives to make this part function properly.

if you do have the right fluid in the diffs...you are experiencing a very typical situation. don't be too alarmed.

i've only had the car for 2 months and i have not changed the diff fluid but with 15k why would some one change it?

[shadowbaby]

what situation are you refering to?

[rallysti'05]

Shadow, the situation i am ref to is the diff bind/clunk.

Many owners with our car get a clunk or binding in the diff especially when turning slowly and sharply. I have heard of this happening even on brand new STi's.

Now, without the proper diff fluid in the rear, it will also cause a binding sensation.

Story for all those who use dealerships. I called up five of my local dealerships to see if they had the 90wt GL-5 subaru diff oil for my car. MY FIVE LOCAL DEALERSHIPS DID NOT HAVE IT IN STOCK. when i asked these dealerships what they used for changing the rear diff fluid, THEY ALL TOLD ME THEY USE THE 75-90 STUFF THAT GOES IN THE WRX. these techs are totally misinformed. i spoke with several techs and parts guys and they all gave me the same WRONG answer.

now, if you are not using the proper diff fluid (the subaru 90 wt is gl-5 and has the proper additives) your diff will clunk and bind!!! makes you wonder how subaru train their tech for our "specialty" car..

so...for all those with any questions. buy the subaru spec 90 wt diff fluid. drain whatever fluid is in there and put it in. it is even easier to do than an oil change.

my 2 cents

for all who have

[SmoothSTi]

My dealership will not even warranty the part if that fluid is not used!

i live in westchester ny. if anyone knows any dealership around me that CORRECTLY services our cars, I WOULD LOVE TO KNOW.

thanks
