Steering wheel moving itself
 

Hello just after some advice,I have a classic impreza saloon and since changing the disc brake and pads the steering wheel moves to the left and right itself and most of the time pulls to the right and sometimes to the left, any help would be appreciated. Thanks

I assume you mean when being driven? But do you mean when you apply the brakes?

Yes when driven, just went through mot and advisery was cv joint gator, could it be this?

Anything that unbalnces the halfshaft could do it. Get it fixed, then see.

Yoy are sure the discs are seated properly? One of the most important things when fitting discs is to ensure the mating surfaces with the hubs is clean and flat.

Does it pull one way under throttle & off throttle pull the other way, or does it pull under breaking?

Just randomly pulls to each side when accelerating normaly

Checked your tyre pressures? Sounds like tramlining, but not so much under acceleration.

Just had new front tyres put on and the tyre pressure checked, had them balanced aswel. The problem was before I had the tyres changed
