Hoping someone could help! My STi V5 judders quite serverely when turning left and right mat slow speeds (usually when parking or turning out of junctions). The noise and vibrations only occur after the car is warmed/heated up, usually after a 25min blast. Originally thought it was worn CV joints but still juddering after they were changed. Appreciate if someone could point me in the right direction. Thanks.

 

Does it have dccd?
If so roll the wheel to fully open and see if that changes, but i think it is deeper than that.

THE expert is David at Welcome to the API website who can advise with no rip off in sight. It will be a good idea to give him the gearbox code off the box, the paper sticker just above the starter motor starting possibly:

TY 754VBAAA

Tell him '911' sent you.

 

It does not have DCCD as its not type r version but a 4 door saloon.

Thanks for your suggestions.

 

How long have you owned the car? I had a very similar problem with my first scoob that was imported with a mismatched rear diff. It was only noticeable after the drivetrain had warmed up and was so bad that the car would barely move at all when trying to do tight/low speed turns. From memory it was like trying to move with the handbrake up and the juddering. The longer the journey and the more heat that built up, the worse it was.

 

I have owned the car for just 4 months, bought as a fresh import. I did not experience any juddering whilst turning when I first got the car. After about a month the juddering became apparent. The sounds and vibrations seems like it coming from the front of the car. However the symtoms do sound very similar as when the car is still cold and you perfom a turn, there are no unusual noises or vibrations, only seems to occur when the car is warmed up.

Thanks for sharing your experiences.

 

You just might have a box with a limited slip FRONT diff, (rare) which was available on your car. It could be the LSD that is in trouble, or the centre viscous diff.
David will tell you.

 

Power steering? Sounds similar to the juddering I get form my MY99 JDM WRX. For the first couple of years it was just a whiney noise and occasional judder. Now it's juddering more often than not when any lock applied. Powerstation confirmed I need a new power steering pump. Was putting it off, but I think it'll have to be an autumn project.

 

Could the juddering be related to power steering? having said that I have also noticed a slight whining noise from my car, also at times the steering feels slightly heavier.

Thanks

 

Good, well that's 2 possibles right there. I wasn't saying that it would be the rear diff if that was the cause, I was just saying that a diff was the culprit in my case .

 

I've just had the car checked out by two garages and they both say that the front diff is playing up.

Thanks for all your suggestions.
