Here is the thing when i am driving everything works fine but when i hit 50mph and turn the when slightly like change lanes to the left the shakes real bad but when i turn normal nothing happens and it only does this when i go left. I checked the the tire pressure i remounted the tires i think it has something to do with the alignment. help greatly appriciated!!!

 

Jack up the front end and see if you can wiggle the wheels by grabbing them at the 3 and 9 oclock positions. It might be something worn in the steering. If you can wiggle them, check your steering arms for any slop in the ball joint. This will cause alignment changes as you drive.

 

if you can wiggle them check wheel bearings too

 

if you're not car savvy, take it to an alignment shop, and have it aligned and checked.

 

Is it just the steering wheel? When my balljoints were bad only the wheel shook really, passangers didn't even notice it (except for the noise). Also might want to check into tie rod ends.

 

yea its mostly in the steering wheel but you hear the tire shake but you dont feel the whole car shake

 

i have the same prob i think, when i switch lanes to the left on highway speed i hear like some thing rubs but first i need to replace the front tires and balnced them before i look into other things cause my steering wheel shakes like a **** at 120km/h

 

could be ball joints or a Tie - rod both cheap to fix on an s4, ball joints not so cheap on an s5

 

found the problem both of the ball joints are bad i get my car back on monday
