steering wheel shaking

[AND1]

when im going higher than 120km my steering wheel shake alot
i thought it was my alignment because my steering wheel was not straight from the beginning. so i went to the garage to do it but it still shaking ,the guy who done my alignment told me that it could be my rims that are not balance.
and after the alignment my steering wheel still not straight so he check it again, and the alignment was perfect,

anyone know why my steering wheel is not straight ? and why it shake after 120km

Well, that's 75 miles an hour....not exactly a slow speed to be consistently traveling.

At that speed, I'd say a tire rod perhaps...or just possibly a rock or bolt in the tred? Just guessing here...

Shaking steering wheel at high speed usually means the wheels need to be balanced. Did he rebalance them?

As for why the steering wheel isn't straight, I have no idea.

as for the steering wheel is there a way to ajust it ? like unbolt the steering and make it straight and rebolt it?

Yes. This is usually done by request during an alignment. Unless something is bent you should be able to get the steering wheel itself facing straight ahead or at the very least quite close to straight.

Lift the car off the ground safely on jack stands -- repeat: safely -- and grasp the front wheels from the top and the bottom. Pull on them and check for clicking or play.

If no play, switch the front wheels for the back wheels and see if the shaking goes away.

hum not sure what you mean by "Pull on them and check for clicking or play. "

With the steering straight and the car safely lifted, grasp the top and bottom of each front wheel and alternatively pull the top toward you while pushing the bottom away and vice-versa. There should be no movement or clicking when doing this.

oh ive done that already no clic or play

Yeah your tires need to be re-balanced. Probably one of the wheel weights flew off when you hit a bump. Or, like me, were driving like a bat out of hell off road .

If you care about what your rims looks like, try to have the guy scrape off the old adhesive because its a real PITA to get off when the wheel is put back on the car. You could be nice and bring Goo Gone or some other adhesive remover in case they "claim" they don't have any. I spent about 25 min per wheel last weekend when I had my new tires put on

Maybe you have warped disc's mate or even a lip on the edge of ya disc's? i've had that once before. if that be the prob all ya do is get them skimmed off on a lathe.
